There's really not much you need to install.  Minimal install + xauth + gedit
and I'd have thought you were there.  xauth is the important bit that you can
accidentally miss off.  You just need to check for ssh X forwarding working.
ssh -Y to your server and "echo $DISPLAY".  If it's not defined, you've got a
problem.

We are shifting the debuginfo stuff around, its taken a few days since
there is quite a lot of content to move around. Give it till this
weekend and you should start seeing content in the /6/debuginfo repo's.

people with the idea of a 'production' setup usually also understand the
idea of 'devel' and 'testing'. People who dont have an idea of
'production' dont need to care about or are already isolated from
needing to care about 'devel' and 'testing', isnt it ?

Re: [CentOS] yum update

For whatever reason, once a year or so, what you describe happens to
me. Fastermirror plugin always seems to add time to my yum commands,
so I disable it permanently and use a local server.

So if I understand you correctly:

If you build and rpm from the current stable release of a package provided to 
you by the people
whom know this package best (its makers), utilizing their automated method that 
they would need
to know for certain works, then install this rpm in a packaged managed system, 
your system
becomes a ginipig for these devels?

Now if someone else takes this same source and builds it, and you install it, 
you're better off?

Uhm, whatever floats your boat:)

I do not have to read it (although I understood you the first time). My 
production server is not going to be a ginipig for developers. And I, so 
far, rebuilt over 100 packages including newer Qt for C6.

There is a repo (ELRepo) run by knowledgeable kernel 
developers/packagers, with 10 times more knowledge about kernels then 
me. And their package was build from most stable version, taking RHEL 
kernel oddities into account, and already tested. Why would I (or anyone 
else) "invent hot water"??

Getting out from the slippery bath tub is one "command" to my brain, but 
I managed to almost cut my palm in two when porcelain sink I was leaning 
onto (I almost never did that before, and never again) broke to peaces. 
If I had passed out (and I almost did), I would not be here now. Crude 
analogy, but very real for me, my thumb lost normal sensitivity for 
ever, as a reminder.

So for me, there is no more easy getting out of the tub, and no easy 
kernel module builds for production use. Not to mention the need to 
follow module development for patches and rebuilding newer versions, etc...

[CentOS] c6 xen guest install, golf, and geany

[Mark Pryor]

List,

Is it possible to do a text install (<512RAM) of C6 server, with support for 
X11 forwarding over ssh, and get geany (editor) to work over ssh?

I got X11 forwarding to work when I have a full Xfce desktop, but not with a 
server setup.

I would like to golf this... IOW find the minimum number of packages.

Any hints or kickstart configs for the needy?

typically, a server will have a SAS backplane which sas/sata drives hot 
plug into, and 1 or more 4 channel SAS ports that plug into the host bus 
adapter or raid controller.  this SAS backplane usually has a 'SES' 
controller[*] embedded on it, which appears to the host as another SAS 
device, and manages the LEDs.   If its a brand name server (hp, dell, 
ibm, etc) using the vendor's raid cards, the LEDs all just work.if 
its whitebox stuff, with JBOD, getting the right failure LEDs to come on 
may require some custom configuration.


[*] SES supercedes the earlier SAF-TE design for the same functionality.

|

Did you install just @core?  I have done @core as described earlier with rsh 
and rsh-server and it just hangs so I'm missing something.  On the workstation 
install it works using the exact same setup so I think I'm missing a package 
somewhere, I'm just not sure which one.

Oh, another requirement: PCI DSS (it's been two and a half years since I
worked for a co that does managed security and was also a root CA). Look
at , and the docs. For any
credit card information, ALL DATA between two systems *must* be encrypted,
and positively, if you need to pull a drive to replace it, you're going to
have to sanitize it, since someone could take it apart and rebuild it, and
get data off it.

So, if credit card transactions might be on it - any kind of PII (personal
identifying information) or HIPAA (for those in the US, medical data) -
you need encryption.

Or if you don't want anyone seeing your pr0n collection

As I understand it, RAID is lower lever then partition, and encryption 
is partition based, so RAID will not care what you have above, it will 
do it's job regardless.

They have sleds. You screw a std. drive into one, and shove it in -

Everything understands hot swap bays these days, and certainly Linux, like
every other version of Unix, does. Let's see, I have well over a hundred
rackmounts in our server rooms and the data center, all have hot swap, and
90% are running CentOS (and a very few RHEL, and a couple of odd things,
and there are the few WinDoze servers (they have hot swap, also).

You absolutely do *NOT* want anything but hot swap. Take a look at the
Dell R[468]10's.

Very interesting, Your response just gave me another question :) If I have
system encrytion on a server with RAID (dont think the type matters, but
lets say RAID 5) and hot-swappable drives and one drive fails. What happens
when you replace the drive, how do you handle rebuilding the data on the new
drive with system encryption? are there online resources/links for handling
rebuilding the data on new drives when the server/PC already had system
encryption. Or are my questions/thoughts on this way of course.

Agree but it requires me to be in physical proximity of the system.
My objective is to make the "HDD failure recovery" process as
deterministic as possible.  As stated in another response, this will
be an appliance running 24x7 at sites where Linux admin knowledge is
likely to be sparse and some sites may not give me connectivity over
the 'Net.

OK, I have understood the value of hot swap bays for disk failure scenario.

Does these bays have a connector (+ cable) that is connected to the

(sorry if this appears basic but I have no experience with such hardware)

Are the hot swap bays compatible with Linux mdadm RAID?  i.e. Upon
detection of disk failure, the respective HDD LED on the bay can be
turned ON?

The 2U system is for an appliance that I am building and it will be a
commercial product.  I plan to order the "integrated" system from
"value add" SIs of Supremicro/Tyan (whover is able to satisfy the h/w
spec.).  My storage requirement is 2TB (4X1TB disks), a 6 disk bay
should be sufficient (or whatever is the lowest denominator).

I am trying to reduce the cost if I can get by
with mdadm RAID10 with additional tools to detect failed drive and
then rebuild the s/w RAID10 when a new disk is inserted.  In some
cases, it will not be possible to service the unit by me and for that
reason I am looking for a visual clue (LED ON) so that I can guide the
local sysadmin.  I may have to go with H/W RAID if it is not possible
to do the same with mdadm RAID.

Thanks for your help.

I've got a BCM5761, running w/ no trouble. Don't know differences, but I

The US gov't, and federal contractors, require encryption on all laptops.
Many companies are starting to go that way. Do *you* really want to read
in the papers, or have your manager call you in (if it's a work laptop),
and tell you what happened to all the information on your laptop? Or how
someone broke into it, and used it to get to *their* network?

Thank you very much for your help. I tested again and you are right.
If I have chance the 'watch' utility can capture the required event as
well. At the other hand, you introduced me with the 'ls -lurt' new

The OpenSUSE source rpm of usbip-* build fine on centos6, but the
modules usbip* is missing

usbip is a staging driver, how to build a staging driver without rebuild
all kernel on Centos6?

intofywait should be event-driven where watch would run the specified
command at intervals so it would be a matter of chance to catch a
momentary event.  You might also be able to see what files had been
accessed most recently with 'ls -lurt' in the directory which will
sort the most recently accessed file to the end of the list.

then installable via yum or apt-get

Okay, look at me being a fool!
While I was shure I added priority=1 to the CR.repo I didn't doublecheck that 
file (I did check my other .repo's). Until now.

Thanks Nicolas and Ljubomir for your time and help!

You can do that as a short term measure, but you really need to solve this.

Try changing link for cr repo to specific mirror from 
http://www.centos.org/modules/tinycontent/index.php?id=30

Also, maybe "yum reinstall centos-release centos-release-cr" might help 
(taking care that it is consistant with your other repo files).

If neither of those things helps, then you should post your content of 
your .repo files.

Excuse me, you are right. I tried again with your "inotifywait"

you should find the el6_1.3.i686 rpm in cr/rpms, it does show up for me:
http://mirror.centos.org/centos/6.0/cr/x86_64/RPMS/glibc-2.12-1.25.el6_1.3.i686.rpm

No luck with that either.
Well, I've found the file when browsing to mirrors.centos.org:

in 6.0/cr/rpms I find glibc-2.12-1.25.el6.i686.rpm 

in 6.0/cr/drpms I find glibc-2.12-1.7.el6_2.12-1.25.el6_1.3.i686.drpm

Your previous explanation of the problem was very clear...
Here is an example when I do:
# inotifywait -m -e access --format "%T %f" --timefmt "%D %T" -r /home/jd/tmp
Setting up watches.  Beware: since -r was given, this may take a while!
Watches established.
$ less toto.php
...
10/10/11 12:33:21 toto.php
It detected my read access to the file 'toto.php' in '/home/jd/tmp'

Maybe this can help:
http://www.cyberciti.biz/faq/howto-linux-get-list-of-open-files/

Basically, monitor that application to see what files it opens. Maybe 
grep to filter only files from specific directory.

Yes there is, I have it on x86_64 system. Try deleting 
/var/cache/yum/ manually, maybe that helps.

Hi Marko,

you can use drbd from elrepo.repo (http://elrepo.org/tiki/drbd83-utils), 
so you can manage this rpms from your package-manager like yum

I am using priorities and base = updates = cr = 1. Normally epel and rpmforge = 
50; but for testing I disabled them.
While I forgot to "clean all" (and started to feel silly); it doesn't help.
Is there a glibc 2.12-1.25  in CR? I get a "No package 
glibc-2.12-1.25.el6_1.3.i686 available." message. For i686 only the 1.7 release 
shows.

Thanks for helping

works here, you should be getting glibc-2.12-1.25.el6_1.3.i686 from CR.

are you using yum priorities? base, updates and CR need the same priority.

otherwise do "yum clean all" then try again, as usual when yum breaks.

[CentOS] Centos 6.0 , DRBD

[Marko Weber]

Hello List,

i am new to Centos and did my first install on a server.
I got it working that also looks inzo the epel repositorie.

Now i want to install DRBD. But yum search drbd returns me only a 
package i dont need.

Do i have to enable the epel-test repo to get itß
But test sounds not stable for me and we switched to centos for 
stability.

anyone here can help me or give me any hints on drbd on centos 6?

Do i have to compile by hand?

I am exactly in the same situation. Our IT department allows access to
their tape archiver only by way of '/usr/bin/rsh server command'. For
well >15 years now.

In my case, what I needed to get it to work was :

(1) install /usr/bin/rsh by 'yum install rsh'

(2) Add the following to iptables :

-A INPUT -p tcp -m state --state NEW -m tcp -s [server IP] --dport
1011:1023 -j ACCEPT

You may want to adjust the port range by examining the ports used for
inbound connections from the server.

Hope this helps,

Akemi

If they are in hotswap bays, yes.  if they aren't, no.

they have 2U servers with as many as 25 2.5" SAS bays now.

[CentOS] [HW] Do the HDD cages in rack mount chassis indicate visual/audio HDD failure?

[Arun Khan]

I have no personal experience with rack mount chassis.

>From the past postings, I reckon there are  members, in this list, who
have experience in rack mount setups and would like get their advice.

To reduce the H/W cost, I am considering Linux mdadm RAID10 on a 2U chassis.

I would appreciate clarification on the following:

In rack mount chassis, do the cages that house the
hard disks have the following feature?

(a) Indicate disk failure. LED lights up and/or audio alarm?
(b) The failed HDD can be swapped.

TIA.
