Not quite the same, but I've a USB drive that I plugged in after
removing "noauto" from the fstab entry.

$ grep 4 /etc/fstab
LABEL=BkUp_4_5  /media/sdc1  ext2defaults,noatime 0 0

Got a nice little message telling me (in Gnome desktop) that I wasn't
priveleged to mount it. That's as I would expect since I was already
logged in at my desktop. Mount showed it mounted.

$ mount
/dev/sdc1 on /media/sdc1 type ext2 (rw,noatime)

Now I'll reboot and see what happens.

Rebooted. Prior to entering "telinit 5", did a "mount" and it was
mounted. After logging onto graphical desktop, one icon on the desktop.
As expected.

I'm led back to the conclusion that there is some oddity about the
device definitions on Mark's problematic unit.

Not as far as I can tell. From dmesg:

BTW. Determination of device type/class is contained within the HAL/udev
data bases (script, configs, hardware lists, ...). If your device is not
there, or is there erroneously identified, ISTM that it could cause the
system to believe it was removable media.

Repeating is not an issue. Long threads promote forgetfulness. But I
didn't forget. I'm just hazarding a guess that whatever the root cause
is, changing those settings might get rid of the extra icon. That, in
turn, gives a hint that might be useful. If it doesn't fix it, it also
provides some help by eliminating some things... I hope.

I'm still hoping that the scan of the dmesg or messages log, in
conjunction with a look a udev stuff might reveal the cause.

The settings suggestion was just a stab at getting rid of the icon,
which was your stated goal.

You mean regardless of if desktop is started up? In that case, it sounds
like System->Preferences->Removable Drives and Media settings need
changing to *not* mount when hot-plugged.

If the "misc" is getting automounted, that would be a problem. But
wasn't the "noauto" option tried (I can't remember)?

I popped a CentOS DVD in, got one image on the desktop and one mount

I removed that and inserted a Mark Knopfler DVD and totem automatically
popped up to do it's usual bitch about plugins.

Mount showed one on /media/SHANGRILA and desktop had one ICON for it.

If it is truly a fixed drive, then I would suggest a look at the logs
(dmesg and/or messages) to get it "identity" and then look at udev
configuration scripts. IIUC, udev is assigned the task of identifying
and classifying stuff correctly. Everything else at "higher" levels of
abstraction would depend on those results.

I did a locate on udev and some promising things popped up.

/etc/udev
/etc/sysconfig/modules/udev-stw.modules
/etc/udev/devices
/etc/udev/makedev.d
/etc/udev/rules.d
/etc/udev/udev.conf

Plus there's a bunch of docs about it up in /usr/share/doc/udev-095,
including overview and writing-udev-rules. "man -k udev" offers some
potential help too.

I hope there's an answer hidden in there somewhere.

The entry in fstab will mount automatically unless noauto is specified.
With HAL, UDEV et al active on your system, it is safe to assume that
one of them is "mounting" the device. At the time X starts, devices that
are handled via this facility will be made available to the user of the
desktop (and "ownership" is assigned to that user too IIUC). I don't
recall seeing noauto in your fstab entry.

Before logging on via X, switch to a vt and type mount. You'll probably
see the device already mounted. Then after you log in via X, do "mount"
again. I expect you'll see two mounts on the device.

AFAIK, that is not a problem except to the "wetware". The system is
perfectly happy with it. See "man mount" and look for "bind" to see
evidence of this.

I'm not that knowledgeable about the desktop, but I think Gnome has some
stuff it starts up that comminucates with HAL or udev to locate
removable devices and make them available on the desktop. This goes
beyond mount, IIUC. Witness a CD or DVD that is a video or music media.
It has no file system, as we understand it, and can't be formally
mounted. I *think* that's correct. Those devices should get accessed
through the raw device interfaces.

Maybe Gnome has some preferences about this?

I see that you have solved. If for some reason you wish to keep both
definitions (there may be reasons), just add "noauto" (no quotes) to one
or both of the entries. This might be useful when you want to mount a
different volume, e.g. as a "temp" mount for backup or copy purposes.
This is handy when you have, e.g., a couple identical looking external
usb drives that are used for different purposes on multiple machines.

With "label" and "noauto", it keeps me from accidentally mounting the
wrong one. No, external labels won't do - purposes change frequently.

As long as the files system does not map beyond the end of a partition
on the target drive, you'll be OK. If the drive geometry *appears* the
same and your target partition(s) are at leaset as large as the source
partitions, you should be OK.

Given the above, the only ill-effects I've seen are intangible. As when
sfdisk gives you a warning about the geometry appears to have been
created for one C/H/Spt but this drive seems different.

Since we all do LBA now (don't we?), no harm.

If you want to be absolutely sure, "man sfdisk". This will let you have
complete control, even allocating by sector count. It will let you save
a "map" of the current drive and apply it to a new drive.

If you are fairly new to this level of stuff (... hmm, even if not),
please have good backup/recovery plans and data if you are affecting
production drives.

Re: [CentOS] fdisk partition table plus sign

IIRC, it means that the partition did not start/end on a cylinder
boundary. I get these all the time when I manually configure partitions
to get every last block used (not since "large" drives were about
500MB).

As to loss, maybe yes. When you allocate using multipliers, (10GB,
100MB, etc.) the bytes per cylinder is used as a divisor. This *may*
leave some part of a cylinder unused at the end. With todays drive
sizes, even anal me doesn't worry about it anymore.

Keeping in mind what the other responders have said, you need to do at
least an informal risk analysis to determine whether it is worth the
effort. Without going into all the formalities of assessment, reduction,
acceptance, assignment, ...

How sensitive is the data and how critical are the functions that that
could be disrupted? What is the scope of exposure to intrusion from
outside the organization (LAN, firewalls, in place, etc.).

How effectively will the enhanced procedures be used? Will users
frequently try to bypass them because it is inconvenient etc.?

OT: does the political environment (e.g. management) support increased
security or does it view increased security as an inconvenient thing
they view as really unnecessary in their situation?

I suspect a difference in ... age, background, personality causes our
different POV on this.

As soon as reading the OP, I deduced that little or no research was done
and no attempt to RTFM had occured. This could be wrong, but it's
irrelevant to me.

That is the OP's problem. I make it a rule to (*try*) not let other's
problems become mine. Especially of an emotional nature.

I realize that is easier said than done. Especially if one has invested
dedicated work and effort. It does take a fair amount of effort to just
to maintain this attitude. When I was youg and full of piss and vinegar,
I 1) didn't know the rule and 2) would have failed miserably regardless.

Now I am able to figure that the strategy of a lot of folks (based on
observation) is to lay as much effort onto others as possible,
minimizing their own effort. This no longer bothers me *as much* as it
used to. It's like getting pissed off because it is raining.

However, having said all that, my response was not intended to be a
criticism. It was only meant to encourage a less ... *reactive* response
to things such as this, which really only ends up wasting your own time.
If the OP is not inclined to do the research it is doubtful that
anything we post here would have much influence.

I *do* sometimes try to ... "educate" folks, but only selectively as I
*think* I see something indicating the poster may be amenable to such
"education".

> 
> But apparently it works to mention switching distributions :)

Only if the OP *thinks* it is a successful "bullying* tactic. Then some
satisfaction might be derived. But if such a tactic fails to provoke any
response at all, chance of satisfaction is reduced, IMO.

But it's really just a style difference ('twixt you and me, e.g.). I
really don't have any animosity toward anyone who "defends" themselves
or their project.

At the risk of looking foolish now, I'll discourse a little from
*memory*. Then y'all can take KB's advice if desired.

IIRC, the snapshot volume holds changes to the base volume that occur
while it is mounted, leaving the base unchanged so that a (e.g.) backup
process sees a fixed state on the base file system. Only changes are on
the snapshot volume and I don't know at what level (changed blocks,
i-nodes, whole files or what). Regardless, when the snapshot volume is
unmounted, the changes are then commited to the base volume. But the
record of those things are still on the volume and it is mountable and
usable independently, implying that there might be complete files on
there. I don't know for sure.

Regardless, the snapshot volume is not a "mirror" of the base and is not
suitable for an unfiltered restore to the base and is not useful as a
full replacement for the base FS.

Someone please correct me if I'm wrong - it'll save me reading again!

Right. I started to say something about that earlier (I have an
automated b/u script I wrote way-back-when that takes advantage of the
snapshot facility) but decided that mentioning that to the OP might lead
to some unexpected hardships for him/her. I decided that just letting
h{im | er } know that it didn't have the full FS was a better choice of
information to pass on.

And in all honesty, it's been so long since I read up on it (vers 1,
IIRC) and looked at the script, I really didn't feel qualified to
suggest anything useful with any certainty.

IIRC, you don't have a real snapshot on the LV ATM. The snapshot LV only
contains files that were chang(ed/ing) while the snapshot volume was
"attached" during the backup.

Don't trust me though - read the docs to be sure. Last time I looked it
might have been vers 1.

I can't help, but if you post your hardware configuration, grub kernel
boot lines, OS status, etc., I bet there is someone that has your config
running that may have something useful to say. Maybe need something on
the kernel line like "lapic" or whatnot.

"Man chmod".

The pertinent part:

 A  numeric  mode is from one to four octal digits (0-7), derived by
 adding up the bits with values 4, 2, and 1.  Any omitted digits are
 assumed  to be leading zeros.  The first digit selects the set user
 ID (4) and set group ID (2) and sticky (1) attributes.  The  second
 digit selects permissions for the user who owns the file: read (4),
 write (2), and execute (1); the third selects permissions for other
 users in the file’s group, with the same values; and the fourth for
 other users not in the file’s group, with the same values

That was it. I wish yum had a "--disablepriorities=" flag. nevertheless,
I disabled all repos, enabled the c5-testing and the update went just
fine.

However...

I know nothing about Java. The real Java worked fine for a java console
and application I use. The application worked (mostly) for Firefox 3.0.
It works very relaiably for the Firefox delivered (and updated to CentOS
current version) on both 4.x and 5.x. The Java Console looks like it
works, but doesn't give the prompts I saw in the real Java (clear
cache, ...) and on Windows XP.

The java-1.6.0-openjdk doesn't. I suspect I'm missing some sort of style
sheet processing. Again, I know nothing. Or maybe it's some
configuration I've overlooked. I looked at all that I could think of
that might be related.

Anyone got a clue bat to get me headed down the right road?

Here's a snippet that represents the errors I see in the Java console.

Another possibility is a hardware related issue. In another thread in
the past, Johnny suggested adding 300K of pad to the ISO image. I use
cd-record. I did some testing. I just yesterday found the floppy that
contains my notes on the results. I will be posting a [SOLVED] to that
thread (I'll find it later) that discusses this.

In a nutshell: some drives have trouble reading the tail end of the
recording on the media. I tested older ones (sounds like you might have
one) and a newer Lite-on. Some worked fine, others failed.

Using dd to append 300K of zeros (from /dev/zero) may fix you issue if
the problem is this one. Symptoms are erratic because the install
continues until it receives notification of the read error, which is
deferred by some indeterminate time.

I've dropped back to the previous kernel to see if that makes a
difference, based on what I saw in the google results I mentioned in my
second post. IIRC, with the previous kernel *and* prev FF, I'd had some
issues, but never a panic. I'd been looking forward to a new FF,
thinking that would fix things. Symptoms were a "slow freeze" when I had
lots of things running on a Gnome desktop (two sets of mail, FF, gnome
terminal for two users - 1 native via login, the other "su -" invoked,
multiple tabs in FF and terminal, and several OO spreadsheets). Doing a
C&P operation would sometimes result in severe lack of responsiveness
from that point on. Might take a half hour until I could even kill
things and start anew.

Various diags would show no swap use, nothing odd about memory usage,
etc. But repainting the workspaces would take a *long* time.

Maybe all this was a sign of that bug in a larval stage.

NB: Maybe this is related?

[CentOS] New firefox causing anyone else problems - CentOS 4.X?

[William L. Maltby]

Looks like Firefox may be getting another update soon, if my problem is
not atypical. Prior to the latest, had NP for *months*. Anyone else
seeing any problems?

BTW, running the recent Java console from sun that was detailed in
another thread a week or two back with Firefox. Had NP prior to the
latest update, if that offers any useful info. Would like to test the
openjdk for us if it's applicable to 4.x. If not, I can still test it on
the 5.x machine.

I am on CentOS 4.x, and a 32 bit system. But I have the same sound
setup. I don't have a clue yet, but I thought if I posted my stuff, it
might help.

First, I think BIOS settings can affect the success/failure/stability of
things. It might be worth experimenting there although you don't mention
having changed anything.

On my system, there seems to be a little "flakiness" re the sound.
Sometimes just clicking the "Open Volume Control" and muting/unmuting a
few things fixes it. This seems to be needed less with recent updates to
the 4.x stuff (again, 32 bit).

There is a kernel parameter that may have affect - see the end of this
post.

I wish that I could be more helpful, but I just use the stuff. :-(

I still use it just because I can mount it ro, if I want to keep it
mounted and that reduces chance of FS corruption if we should an
unexpected disastrous event. Although I don't anymore, I also used to
have separate ro partitions for the infrequently changing "critical"
parts of the root file system. With the robustness of things these days,
I've found that less useful.

But because I still do a lot of dinking with stuff, the separate root is
worthwhile (see below).

Only through the grace of high metabolism, I'm still just a belt guy,
even at my advanced physical age. Mentally, I'm suspenders sometimes
though.

I do the same with one minor change, ignoring naming conventions. All
systems have two bootable drives and my backup boot and base root are
duplicated, with minor mods, to the second drive. That gives me a
fallback not only for my screw ups, but also for HD failures.

This looks like a normal shutdown command was issued from somewhere,
IMO. I would check the other log files under /var/log and its sub-
directories for entries around this time. Especially secure.log*. Also,
I don't know your configuration, but is there a cron or at entry that
has a scheduled reboot?

Ditto. Although I should mention that unless you "man bash" and find the
magic incantation I can't remember that gets return codes from a
pipeline (if that's what "~>" is supposed to be), the return from the
last command in the pipeline is what's returned. If echo is from bash,
as I expected, it should not fail and should return a 0 code regardless
of what happened ahead of it.

Your best tack is simplicity: one command, no pipes, just redirect
output with "&>" like so

   cat  &>/tmp/test.out

Then you can see if the output file has greater than zero length, use
vim on in (if that works), etc.

Ssh via e'net or serial? On the console, is the failure as reliable or

I would surmise that means that basic kernel operations are good and
there is some common library routine involved.

Well, I'd "man rpm" (no, I don't hate you, but I don't do rpm stuff
enough to remember it all and *I* am not going to "man rpm" unless I
suddenly become quite masochistic :-), select some promising looking
options and run it again, redirecting output to a file you can examine
(possibly have to get it to a machine that works reliably - "man nc"
someone mentioned in another thread looks like a useful tool).

You want to get the diagnostic output from rpm and see what files it
complains about. The ones tagged with a "c" are config files and will
often show up there. If your system hasn't been compromised, it's safe
to ignore these.

Examine all the ones that were unexpectedly tagged and see if there is a
pattern.

If your HDs are "smart", maybe a "smartctl -l " will
identify some sectors gone bad in a critical area of your HD.

I don't have a clue why right after prelink is run the rpm would claim
they had been changed, unless it's a matter of the rpm data base has not
yet been updated. I don't know how it all works together. Maybe the rpm
update runs at night or something?

WHERE'S THE KNOWLEDGEABLE FOLKS WHEN NEEDED? It's the blind leading the
blind ATM.  8-O

Hmmm... Sure it's failing? Maybe just the output is going somewhere
else? After the command runs, what does "echo $?" show? Does it even
work? Echo is a bash internal command, so I would expect it to never
fail.

What is your output device? A serial terminal? If so, could be simple
flow control issues. In fact, any serial connection (even a PC emulating
a terminal) could suffer from flow control problems. And they would tend
to be erratic in nature.

If you are on a normal console, try running the commands similart to
this (trying to determine if *something* else is receiving output or
not)

 &> /dev/tty

if this works reliably, maybe that's a starting point.

There's a couple kernel guys who frequent this list. Maybe one of them
will have a clue as to what could go wrong. Corrupted libraries and
whatnot.

You might try that rpm -V command earlier against all packages (add a
"a" IIRC). Maybe some library accessed by the coreutils, but which is
not itself part of coreutils, is corrupt.

Generally, there is no printer-specific support in CentOS/RHEL. Usually

DESCRIPTION
   vgimport allows you to make a  Volume  Group  that  was
   previously exported using vgexport(8) known to the system again,
   perhaps after moving its Physical Volumes from a different
   machine.

Essentially, IIUC, vgexport updates the LVM configuration to remove the
group from the system. I *guess* it might also put some status
information into the descriptors on the volume being removed so that
critical information is available when a vgimport is done.

I can tell you from first-hand experience that moving the volume without
doing this makes for extra work when re-installing, though I can say
that it can be done. Again, from first-hand experience.

One of the *few* advantages to not using LVM. Overall, I'd rather use it
in most cases.

It looks like Niki's also left things alone. It went into a 3.0 sub-

By the time I saw you post, I already had installed an updated Java and
Java Console plugin. I would have been glad to test that as well.

I'll try and catch it next time around.

As I mentioned, things sped up considerably. I got 3 installed, after
removing the 2 that was on there (Karan, the 1.* from original install
is still there so I s/b OK when the new release comes out), got the
plugins done (esp. Java and its console for an app that is fairly
importatnt to me - means I don't have to do Winblows) and looks pretty
good.

It picked up my old user config stuff OK and worked well.

Only observed problem seem to be with a screen layout on a certain
website. Some "tabs" it presents are partially hidden and no amount of

to browse in settings a bit and see if there is something there that
might cure that problem.

But it'll do what I can use it for.

I've got to say thanks.

Kiki,

It looks like it will take about 13 hours to download. I'm afraid I
would soak up your outgoing bandwidth. If I don't hear from you in an
hour or so, I'll kill it.

I guess this reinforces Johnny's earlier comments in a thread about
torrents giving full speed download regardless. I could host a torrent
if I do get it all down, but start up would be slow as my upload speed
is not great either (appx. 60KB/second). But once it got going, if there
were a lot of participants, it would do well.

OTOH, with an estimated early May 5 upgrade release, it may not be worth
it?

BTW, printer is a Canon BJC-4550 bubble jet photo quality, wide.
Supported in cups with a similar entry, bjc-800.ppd.

As stated, worked fine prior to the 8.1 acroread install, and after
removal or 8.1. Also worked with orhter normal applications, firefox,
thunderbird, evolution, CLI, etc.

When it first came out with 8.1, it would not print. I use CUPS. Version
7 worked fine for a long time. I tried modifying the print command in
various ways and never got it working. I googled and saw several
complaints about the same problem. Tried the (very) few solutions
suggested. None worked. I can't recall seeing any responses from the
posts that indicated anyone else got it working either. Again, that was
when it first came out.

I don't remember the details of the failure now. IIRC, it was failing to
connect the output from the PDF to the input for the printer, I *think*.
I tend to get disgusted when things like that happen - a new version
that has a failure in such a basic function that has been well defined
and working across many platforms and software packages for years being
broken when an "improved" is released indicates a QC problem in my view.

I uninstalled it, reinstalled 7, changed nothing else and print worked
again.

When 8.2 was released, I pulled it down and looked at the change log. No
mention of a fix. So I didn't even try it. Why waste my time when 7
works just great and does everything I need?

Anyway, it may be working now. I wouldn't know, based on my experience
and the change log.

 I use Adobe's acroread. Works very well. But don't get the 8.* series -
it's broken in printer interface and is a little bloated do to a not yet

Well, no luck. The only errors of note were the missing gaim dependency
for nautilus-sender (now replaced by pidgin and reported upstream by
Johnny) and a missing dev entry. The rest were size and configuration
files. I forgot to re-run with the md5sum checks turned on last night,
but I have no *other* indications that there might be a problem there.

I've started it up now. It's early enough that I should have some
results before the day ends.

Well, we can put this one to bed. Over the last two weeks, only 1 bad
sector showed up in the automatic short test and one more in the
extended offline self test. No signs of further deterioration.

As I mentioned earlier, the two sectors are in unused portions of the
disk *and* the HD is not my root, something I overlooked earlier. So it
contains only backup, my LFS boot/work areas, and a part used for /home
for my migration to 5.x. Further, each HD is on a separate SATA port
(DUH!), so there's not a single failure point in the cables or port.

My feeling is this isn't related to my evolution update problem.

I've left the rest of the previous post, the rest of this message, JIC
anyone who's interested missed the earlier parts of the thread. If you

By the time you read this in the A.M. I should have a new smartctl
extended selftest completed. Then I'll get the diags if it seems things
have deteriorated from my comfort level.

Looks just like mine looked. I did go a-googling and found some
possibilities.

None are related to evolution, but I'm hoping that clues lie there for
discovery by some skilled viewers of this thread.

Here, they claim that the oasis site is broken. But since I did a wget
successfully, I still suspect my installation has something wrong. But
rpm --verify doesn't give a clue, more later.

# Wrapped line
http://www.archivum.info/debian-bugs-
dist.lists.debian.org/2004-12/msg07181.html

And in the follow-up to this, they mention the need to have a version of
docbook installed and using --disable-gtk-doc. But this has to do with
building pacakages.

http://www.cygwin.com/ml/cygwin-apps/2005-08/msg00315.html

In the next, broken rpm macros are suggested. It starts here, but I'd
skip to the second URL as it seems to get closer to the germ of truth..

 Site seem to take great glee in presenting lots of "cutesy"
animated little ads that slow things noticeably.


The stuff beginning here doesn't *seem* related to my ignorant eyes, but

Thanks Lanny. I just finished an rpm verify and see lots of size
changes. I think these are from prelink, IIRC. The usual T and c flags
(mtime differs and c means it's a configuration file). I'm still plowing
through the output. I suppressed md5sum checking for this pass because I
recall that when things are prelinked, rpm will "unprelink" to a
temporary file and then check. A slowdown may be noticable.  :-{

I'm hoping I can locate the trouble without having to do that now. I'll
run a more thorough one tonight while I snuggle comfy in my haystack.

Did find a missing dependancy for nautilus-sendto, libgain.so.0. Trying
to see "whatprovides" that now. All indications are I'll have to go a-
googling for that one. Yum and rpm both seem to indicate it's a bastard
child.

I remember locating it before in the dim dark past. Can't remember now
though.

<*sigh*>  They say your memory is the *second* thing to go.

I just tried again and got the same errors as in my original post. I'll
run a verify on my system and see if something got corrupted. I have
seen two unreadable sectors from smartctl selftest output in a currently
unused portion of one of my HDs. The rpm verify and another smartctl
selftest may provide a clue or two.

I hope no more bad sectors show up. If I see more than just a few I
believe things tend over successive self tests, I tend to have a
pessimistic outlook for the drive.

[CentOS] CentOS 5 Evolution Update errors.

[William L. Maltby]

Folks,

Evo update on my 4.x worked just fine. 5.0 generated a bunch of parsing
errors preceded and followed by a couple of I/O errors that appear
related to an unavailable URL.

I first figured corruption on my node, so I yum erased evo, its -
connector and -webcal units. The data-server removal looked as if it
might remove half my Gnome desktop, so I left it in place.

Then I did a selective reinstall. The edited results follow. I believe
the very first error is the cause. I erased and installed multiple
times, even trying the connector plugin figuring maybe it was needed to
download files from a website. No-go.

I was able to wget the docbook w/NP.

Any suggestions? Not critical, I only run evo on my 4.X. But I've begun
a slow and careful migration to my 5.0, letting it serve as back up for
now.

TIA

I think Ross is right. At my last contract with IBM some years back, we
were doing some raw socket stuff. ISTR that we had no problems because
we were real root applications. IIRC, docs specified root privileges.

Suggestion for future faster "finds":

After installing/removing components, run updatedb. Then instead of
find, you can "locate swriter". You'll probably need to filter the
output as locate's match seems to be very regex-generalized.

Also, if updating components that have control files, locate rpmsave and
rpmnew so you can see if any of your configuration files need to be
examined.

for the lazy way or "man gawk" to see how to select and print and skip

Do you remember if you used the --link or -l parameter? That's the one
that says hard link when possible rather than copying. That should
prevent multiple copies of the same file when multiple hard links
reference them. That should be faster than not doing so if there are
lots of hard links.

If you use cpio, it can handle the hard links intelligently, IIRC. That
may make this more feasible. Plus you can specify such things as depth
to the find command feeding cpio so that even directories end up with
good dates.

You can also suppress atime updates, making it both faster and non-
intrusive.

General strategy: 1) maximize local operations to minimize intrusion
into the time-constrained resource window by using out-of-band available
resources and 2) minimize in-band demands.

> But I can't take it for granted that this will always be the case.
> Any ideas would be appreciated. What do you mean by local staging?
> 

1) E.g. if local HD space is available, do a local rsync from live ->
backup copy. This can be done even during normal hours while users are
making files (at low priority - see "man nice"), *prior* to the
communications window, *if* something like LVM snapshot is available
(that way you can be assured that activities starting in the live
environment after local copy begins don't get included, although
partials started prior to the copy can still get in there. But they will
be "corrected" on the next cycle).

In this scenario, it may be easier to use one of the "canned" utilities
like amanda or backuppc that have been extensively discussed on this
list. I've never used these things, so I don't really know if they are
appropriate in this scheme. However, nothing wrong with hand-crafted
stuff if you've the inclination and need.

Keep in mind that over time the local rsync will tend to take longer as
directory numbers and sizes grow unless there is also a significant
amount of file deletion by the users going on. So you may want to
schedule several low-priority snapshot/rsync runs throughout the
workday.

Don't be afraid to seek/request some kind of raid/NAS/SAN resource if
the data is mission-critical, growing constantly and volatile. It may
not be needed now, but look down the road so you don't get into a
constant cycle of scrambling to keep up with needs.

Ditto for additional band-width to the remote. It should be cheaper in
the long run if resource demand is certain to grow significantly.

> I'd like the backup to run from 7pm to 7am and then if it didn't finish to
> resume again the next night.

2) You mention images, so I'm not sure much can be gained by compression
because many types of image files are already compressed to a great
degree. But if there are a large number that can be (further) compressed
for significant gain, compress them *prior* to the start of the
communication window. You may need to do some testing to tell which file
types are suited for further compression.

The downside to this is that you no longer have an rsync-amenable image
on the backup local side. Additional scripting would be needed and
instead of rsync, hand-crafted copy operations would be needed. However
this is easily overcome using a time-stamp file in conjunction with
find's "time" parameters to select only things which have been modified
since the previous local copy started.

Another downside is that to restore from either the local or remote
copies, decompression would be needed. This is quite fast though. But,
again, some additional hand-crafting would be needed. Thorough testing
too.

> That way when nothing was added/edited on the weekends the backup can catch 
> up.

In conjunction with "lock" files mentioned in another reply, you may be
able to gain something by segmenting the local and remote rsync. This
allows 1) concurrent *local* compression and rsync (if CPU/memory
resources are sufficient to avoid unduly slowing the user's activities -
again "man nice" to reduce the effects on users) and 2) easier
management of the remote rsync start/stop on directory boundaries as the
window is entered/exited. This may not be needed at all or may be of
limited benefit.

Lastly, see if it's possible to run the rsync during normal hours. If
your site has upload of 750KB/sec and during 90% of the normal workday
only a small percentage is consumed, take advantage by doing some of the
rsync (maybe in small chunks) during these hours at low priority and
throttled appropriately. Presuming that most of your activity is
download, not upload during the normal workday, and knowing that most of
the rsync activity will be upload, not download, there is an opportunity
there.

Testing this scheme before opting for it would be advised.

Finally ...

In that case, it sounds like you need a local staging that can be
quickly done before starting upload sync. Then the upload can run 24/7.
How you might want to deal with new updates that happen before the
previous upload finishes is going to be an interesting problem.

I agree. I just calc'd it out at roughly *maximum* 12.5MB, assuming
standard packet sizes. Plus, IIRC, OP said link was 750KB. I don't
recall if OP was trying to resync over that or over and internal 10 or
100 LAN. If over a LAN, I can't figure what the ISP 750KB link had to do
with anything.

Priority *and* protect? Supposed to be a no-no.

Worse, it's on the updates too. I would carefully examine all your repo
defs and have *either* protect or priority, but not both. Also make sure
the settings are appropriate sionce you've add some other repos.

I've been using Rpmforge for a long time, NP. But at the time I
established priorities, I disabled all protect settings.

And there are a couple exclude and include setups for a few special
instances.

[CentOS] Centos Guys: Any estimate of recent torrent savings?

[William L. Maltby]

Just wondering if the community has any stats available from the tracker
showing savings from torrent (up|down)loads. I'm seeing *lots* of
activity on the live CD. Between that and the two CentOS releases I'm
sharing (4 DVD & 1-4, 5 DVD & 1-6) my current session has sent out about
20.3GB.

Since I started using it regularly, I think I've sent >= 0.4TB.

If some really good numbers were available, it might encourage others
when they realize that all this translates to faster syncing of mirrors,
faster initial release downloads, reduced costs to the project, etc.

I recently increased my cable modem speeds (U.S. $10/mo seemed worth it
to me even though I don't get the benefits of the added download speed
often - nature of what I do and all that) so I could upload appx. 60KB/s
instead of the previous appx. 45KB/s. And the new {lib, r}torrent from
rpmforge has DHT capability included, which I activated, and I think is
increasing the number of peers/clients with which I see exchanges. I
don't know how badly this might cause under-reporting of your stats.

Just curious, no big need.

For the Q posed by the OP, "man mount" gives this hint.

===
The proc file system is not associated with a special device, and
when mounting it, an arbitrary keyword, such as proc can be used instead
of a device specification.  (The customary choice none is less
fortunate: the error message 'none busy' from umount can be confusing.)
===

Note also the default mounts my CentOS 4.x shows

$ mount
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

On proc, sys, pts and shm, the "none" comes from /etc/fstab, modified by
fstab-sync (see the man page for it). But IIRC from long ago, anything
that doesn't have a real device associated with it, like these, can take
any value for the fs type. Back then, sentiment was sidling towards
avoiding "none" due to the potential confusion it could cause in casual
users and the fact that hum0n eyes could more quickly scan and identify
desired items when a "rational" value appeared in place of "none".

Note that the sunrpc is different - it seems to be a result of the
loaded module sunrpc.

$ /sbin/modinfo sunrpc
filename:   /lib/modules/2.6.9-67.0.4.EL/kernel/net/sunrpc/sunrpc.ko
license:GPL
vermagic:   2.6.9-67.0.4.EL 686 REGPARM 4KSTACKS gcc-3.4
depends:

Lsmod shows a use count of one, but I don't see any module using it.

However, the modinfo output in conjunction with output of this command
(I won't include the output, there's more than a line or two) makes me
think that's it's a foundation piece for RPC stuff.

I've not tried 8.1.2, but IIRC I did download and check the changelog. I
was trying to address a general problem mentione here:

http://lists.centos.org/pipermail/centos/2008-February/094078.html

Normal. Default operations for things like fdisk is to operate in units
of "cylinders". The first cylinder often goes completely unused except
for the MBR. The last is often only partially used. In the past when
drives were physically large, small in capacity, expensive, unreliable,
noisy, ... I would manually partition in advance to use every last
sector on the drive. I had no worries about other idiots trying to
follow up on my work then. Or MS Winbloze OS's - I only did *IX as a
rule.

The downside is putting up with stupid messages from utilities
complaining the things don't start/end on boundaries.

Ahh! Those were the good ol' days when we were actually smarter than the
tools we used!  :-[  And our services were not a commodity.

I presume you mean switching between a virtual console and an X session,
or between multiple X sessions. AFAIK, it can't be prevented because the
video output to the display changes and the monitor takes a brief time
to re-sync.

When I have run multiple X sessions, even when the resoultion is the
same, the black screen stills appears for a second or two.

Do yourself a favor, as you'll probably have several more comparisons to
do.

When making the lists, sort the output, either piped to sort or make a
sorted version afterward, and use comm (man comm). You can see a nice
consolidated output, or select any combination of "only on file1", "only
on file2", ... both, etc. Makes detecting differences much faster.

Beyond my ken on the checkpoint frequency. Never had to use them. I'm in
a situation where I can start 'em up and walk away. My best thought is
to read the description of it in the man page and make a best-guess
about letting it run or not.

Sorry I can't offer more, but I'd being spewing FUD if I tried!

I suggest that with an estimated 1 week completion, you can't lose much
by killing it and restarting. Other checkpoints I've used in the past
have *very* low overhead and easily justify their use.

I would anticipate this to be the same. IIRC from the man page
description, it is essentially just marking completed portions and
updating metadata to reflect the new status. With such a straightforward
process, restart should be almost instantaneous with very low loss of
time.

Again, this is all supposition as I don't know the code.

If you run pvmove from the command line, "nice -20 pvmove" for example.
If you start lvm and run pvmove inside that, then "nice -20 lvm" e.g.

But based on the  1% CPU usage, probably won't help much.

My guess then is that the writes to the HD are just large and slow. If
the two HDs on the same channel that would make it even slower. If the
drives are older/slower models, ditto. If they have small on-board
cache, same thing.

But I really have a hunch that it is just a lot of I/O wait time due to
either metadata maintenance and checkpointing and/or I/O failures, which
have very long timeouts before failure is recognized and *then*
alternate block assignment and mapping is done.

I finally thought about that last line. Makes since because meta-data
tracking must be done as various pieces are moved and a checkpoint is
written (note in the man page about being able to restart without
providing any parameters). And that is the drive that is failing too!
May be a lot of write failures followed by alternate block assignments
going on at the hardware level. Just a SWAG (Scientific Wild-Assed
Guess).

Not that I am aware of. Keep in mind that a *lot* of work is being done.

You could "nice" it. "man nice". Since there is likely to be a lot of
I/O happening, it may not help much.

If the drives are on the same channel, or other devices on the channel
are also flooding the channel, that would be expected. Does "swapon -s"
show a lot of swap being used? Does top give a clue? I suspect a lot of
CPU may also be involved.

Check BIOS settings? For memory, CAS etc. the same? Disk hardware the
same and specified identically?

Presumming that nothing is found there, install system accounting
packages and run some SAR reports. You may see a clue in them.

Any "tweaks" on the old system you forgot to apply on the new? Elevator,
buffer flush interval changes, etc?

Any other noticeable things on there that may cause it? Presume the
slowdown is caused by a process that you are not looking at. "Hangs"
while some other process is waiting or tying up the CPU. Try running
top.

I notice an execve shows on the new one that is not in the old. One says
"hmmm".

What does swapon -s show?

Is the system "seeing" the same amount of memory "available" or have
BIOS settings in one reduced available?

If all new equipment on the new one, open her up and reseat all
connections, PCI cards and mem sticks. Make sure all power connectors
are well seated to MB and drives.

Front side bus and memory speeds set the same in BIOS?

That's all I can think of that may be even remotely related ATM

Well, the 8* version doesn't seem to want to print using standard
established CUPS etc. Info obtained via Google seems to indicate that
many have this problem and it is internal to the 8* version. Presented
solutions seem cumbersome and not worthwhile, IMO. And many didn't work
anyway!

I've regressed to the "standard issue" 7* version and printing works
again as expected.

Other partitions on the (apparent) device in use? If so, you need to
umount them and then (I use) sfdisk -R . If the fdisk
changes were written to the device, this should reload the kernel's view
of that device.

BTW, *before* shrinking the partition, be sure the (live?) file system
has been shrunk (if shrinking). If enlarging, do the resize2fs *after*
the kernel knows about the new size.

Other: if LVM is active on that partition or device, it also needs to be
inactive ATT the fdisk/sfdisk is done. This means that LVM meta-data for
the partition may be incorrect after changes have bee done.

It threw me for a loop first time I ever saw it. Especially when (for a

I guess that means the OP should check the logs for the DISCOVER...

If you control the DHCP server, you should be able to set the reserved
range. Also, you should be able to extend the lease/renewal times to a
*very* long interval. If you don't ... I'm lucky, IPCop is my friend.

Regardless, if it's losing the IP and not getting re-assigned another
(or same) one, something else must be wrong somewhere.

Keeping in mind that I'm really ignorant about this stuff, if it were my
unit I would be looking to see if I had conflicting setups somewhere.
Like maybe booting into a static private IP address default
configuration and yet having a DHCP client active. I don't know if
that's possible or rational, but like I said, I don't know much.

Did you use system-config-network for initial setup? If so, I would
think subsequent diddling would be the screw-up. If not, initial
diddling probably the culprit.
