Now the problem I have with your approach under the OP's

or hosing it in the process.




I've never had any problems with linux losing track of md based raid 
mirrors or LVM configurations, and they import quite nicely into new 
systems.



I'd consider using a SAS card on the host (LSI Logic makes some nice 
ones), and each SAS port can drive 16 SATA drives on SATA/SAS backplane 
multiplexors. 
http://www.lsi.com/storage_home/products_home/host_bus_adapters/sas_hbas/lsisas3801e/index.html


I'd start with a 3U 16 bay /server/ using a SAS/SATA backplane, too, 
then when that fills up, add 16 drive expansion bays as needed...
something like http://www.aicipc.com/ProductImage.aspx?ref=RSC-3ED2-2 
(but, by all means, pick your favorite chassis or system vendor)

Re: [CentOS] Postfix+MySQL - how to create DB

2008-05-06 Thread Liam Kirsher

I used postfixadmin and it has been fine.  (CentOS 5)
I suggest redirecting (in the http server) all postfixadmin access to 
https for security.

I found the db schema satisfactory for my needs.
The point with postfixadmin is the PHP interface to the database.
You /could/ just create whatever tables you needed and edit them with 
phpMyAdmin,
but postfixadmin gives you a simple interface that users and domain 
admins can use.

The one thing that puzzles me is the table structure for the postfix

some people create more tables than others.  But, this looks like it's
just based on which bits of postfix people want to put into the

I can just copy the SQL people have posted to create the tables I want.
I'd much rather know if there is an official source for this, though. So

Re: [CentOS] I need storage server advice

2008-05-06 Thread Ross S. W. Walker

Take these benchmarks with a grain of salt.

We don't know how these hardware controllers were setup and by the numbers 
posted, not very well, or they are not very good.

A SATA and a SAS drive will have roughly the same sequential io performance. 
Where SAS shines is in random io. So if it's archive, buy SATA.

65MB/s is roughly what you will see with a single SAS or SATA drive on reads, 
around 30MB/s for writes.

Sequential io is measured in MB/s and random io in IOPS or ios per second.

Each spindle in a stripe set will roughly add 50% perf to sequential io and add 
to the IOPS by the IOPS of the spindle (IOPS+IOPS...). A mirror counts as 1 
spindle for reads and 1/2 a spindle for writes (unless RAID is capable of doing 
parallel reads then it counts as 1 1/2 of reads). A RAID 5 is always one less 
spindle due to parity and each spindle on writes counts as 1/#spindles 
(write-back cache helps lessen that hurt).

For 4k sequential ios (larger block sizes will post larger numbers).

1 spindle = 65MB/s and 175 IOPS
2 spindles = 97.5MB/s and 350 IOPS
3 spindles = 146.25MB/s and 525 IOPS
4 spindles = 219.375MB/s and 700 IOPS

(175 IOPS is from 15K SAS with 3.5ms read seek and 2ms avg latency, figure 80 
IOPS for good SATA drive)

Now any performance below those numbers is a failure of the RAID system and any 
performance above those numbers is due to caching and read-ahead.

I hope that helps.

The solution I found best was to buy a 2U server that has 8*750GB disks,
though they'd probably be 1TB today.  Put the disks into a RAID 5 or 6.
Using hardware RAID, divvy them up into one 50GB drive, and one really large
drive.  Put the OS on the 50GB drive, mount the really big drive.

Now you have a 50GB drive and a 7*750-50 drive.  When you fill that up, just
buy another 2U server.  When you do fill it up, the next one will be cheaper
and or bigger.

The keys to this type of setup are:
1) Don't buy storage you'll need next year today.  The best time to buy this
kind of hardware is right before you need it.
2) Look at the overall cost per gigabyte.  That's the metric that drives
things.
3) Understand your tolerance for downtime and data protection.  If you have
another copy, or a backup, and its not mission critical data, its much
cheaper not to waste disks on redundancy.

We have tape backups of our systems, and factoring in the cost of tape and
other costs, its still possible to get storage with a marginal cost below $1
/ GB.  That includes a 3 year warranty, quad core processor, 4GB of RAM
which you can probably put to use elsewhere.

Well that's a hell of a lot of storage for a cheap project. Instead of
a Dell MD3000 appliance try a Dell 860 1u server (Quad Xeon) with the
LSI PERC 5e 256/512MB RAID controller there you can chain up to 3
MD1000 JBOD SATA enclosures to it. It can handle mixed SAS/SATA drives
and can hold 45 spindles across 3 enclosures per 1u server.

The 1u device will be a SPOF but you wanted cheap...

With the 1u server you can always upgrade the OS as the data is stored
externally. Hell you can even swap out the 1u 860 for say a 2u 2950
as needs grow which gives better redundancy as well as internal storage
for snapshots or some other use. Just get the 860 with 2x250GB drives,
and create a software mirror out of them. You can always break the mirror,
upgrade the OS and if it works re-mirror, otherwise boot the old half
and re-mirror.

ext3 can go up to 8TB, xfs and jfs can go up to 1EB which should hold
you.

You can also check out OpenFiler which has NAS and iSCSI included.

Re: [CentOS] I need storage server advice

I just purchased an equallogic SAN with 16 1TB drives for 52k at work.
Love it, scheduled snapshots, thin provisioning, iscsi only but fairly
swift at 16 spindles in a RAID 50.

1TB drives are available now.  5 years from now, who knows?

since your data is archival in nature, it really shouldn't be that hard

you fill 2TB, take 8 x 500GB more SATA drives, raid10 them, and mount

If it's really rarely used and you have a sensible scheme to find it you 
could just have a drawer full of inexpensive external 1TB drives that 
you can plug in on demand, using USB, firewire, or sata connections.

First consider whether you can organize this into 1 TB or smaller 
partitions that are mounted separately.  If you can do that, growing the 
space is trivial - and you get the advantage that you can do raid1 
mirrors of individual drives which gives you the ability to recover data 
from any single disk.

Don't put the permanent storage on your system drive(s) at all. Add one 
or more directories after installation and mount the additional 
partitions or raid arrays there.  Then if you do a new install, just 
uncheck the devices as disks that can be used for the system and add the 
mount points back when it is done.   But, there are lots of other ways 
to lose data.  If you'd need it after a building fire/flood or operator 
error you should build two of these and rsync to somewhere offsite.


Storage limitation.  It is my understanding that there is a 2 TB storage 
limitation with Linux (and windows) in general particularly for 
stability. 


I think that's 8TB if you don't boot from it.  But that's per mounted 
filesystem - if you can have smaller separate partitions, it won't matter.

[CentOS] Slightly OT: Extra icons on desktop - SOLVED

2008-05-06 Thread MHR
I can't think of a better word for this than "weird."

I went back and reread most of the emails on the original thread, and
both Ross and Bill suggested that something about "misc" might be off.

So, I created a new mount point called "other," pointed fstab at it,
modified my scripts and symlinks that used to reference /misc, and
rebooted.

Voila!

/other was automounted, as I wanted, and there's only one icon on the
desktop for it.

I did notice along the way that /etc/rc.d/rc.sysinit had a mount -a
with a -t list of types of FSs to mount, which did not include ext2 or
ext3.  I added those, and that did not help the /misc situation.

Apparently, there is something funny about /misc in FC8 (is that true
in CentOS?).

Anyway, problem solved, thanks to all, enjoy your day, etc., etc.

You have to be careful, but it's quite easy to leave partitions (and thus

You cannot boot from a device larger than 2TiB, but that's the only 
limitation at that size.  I run several multi-TB servers (including over 
8TB) on CentOS-5 with no issues (using ext3).


You do not want to use ReiserFS.  It's not supported under CentOS, and 
it's future is far less than certain (and I do not want to restart *that* 
OT conversation).  ext3 is the default FS under CentOS and works pretty 
well.

[CentOS] SELinux, postfix and milters

2008-05-06 Thread Michael Saavedra

Hi all,

I'm trying to add some milters (particularly spamass-milter and 
clamav-milter, which I acquired through rpmforge) to my postfix 
configuration on Centos5 with the targeted SELinux policy..


I'm running into difficulty getting postfix to communicate through the 
unix domain sockets created by the milters, because selinux keeps 
blocking them. I've attempted to use audit2allow to fix this, and made 
some progress in allowing postfix to write to the socket. I'm getting 
stuck on the following audit.log error, though.



type=AVC msg=audit(1210016235.033:6265): avc:  denied  { use } for 
pid=17995 comm="cleanup" path="socket:[372498]" dev=sockfs ino=372498 
scontext=root:system_r:postfix_cleanup_t:s0 
tcontext=root:system_r:postfix_smtpd_t:s0 tclass=fd
type=SYSCALL msg=audit(1210016235.033:6265): arch=c03e syscall=47 
success=yes exit=1 a0=9 a1=7fff0ec2f220 a2=0 a3=0 items=0 ppid=17983

fsgid=89 tty=(none) comm="cleanup" exe="/usr/libexec/postfix/cleanup" 
subj=root:system_r:postfix_cleanup_t:s0 key=(null)



I use audit2allow to try to fix this, but the resulting rule:

allow postfix_cleanup_t postfix_smtpd_t:fd use;

does nothing to help. Has anyone succesfully added unix domain socket 
based milters to postfix without disabling selinux? If anyone has any 
suggestions, I'd be grateful.


Thanks,

Kai: This is a follow on to my prior reply to this. I removed the
plugins=1 line in /etc/yum.conf and I removed 6 repositories. Then, I
did "yum clean all" and got "Cleaning up Everything". Then, I did "yum
update" and got, "No packages marked for update/obsoletion". Then, "yum
update kernel" and got "No Packages marked for Update/Obsoletion". Then
the yum.conf file type is shown as Cisco VPN Settings, so I couldn't
open/view it with a text editor. 

The last thing I did was to copy these files on my box and replace the
files on my wife's box with my files: (a) etc/yum/folder (b)
etc/yum.repos.d (c) /etc/yum.conf file

Same problem.

It is as if there is a YUM or RPM database, somewhere, that believes the
Kernel has been updated, and it has not been updated?

I find it very hard to believe that the Kernel was in fact updated, but
that it is still shown as the original Kernel that was on the CentOS5
Install DVD.

So, this continues to be a an unsolved mystery, but not like the
ReiserFS guy.  :-)

I changed the setting for my subscription to the CentOS Mailing list,
from the Daily Digest to Individual messages.  This reply is to your
message that was in the Digest I received Sunday morning. In the future,
I will be replying to individual messages (using Gmail on the web or
with Evolution), so, hopefully, the threading will be better, if not
perfect. Gmail doesn't use Folders, they use Labels, and I don't have
that working on the web yet, but I can move the CentOS messages into the
CentOS Label in Evolution and because it's IMAP, they get moved into the
CentOS Label on the web too. Something else for me to check out, but
that's on the Gmail web site somewhere and will be much easier to cure
than this mystery about the kernel update on one box.

All of your ideas about the problem updating the Kernel in my wife's box
are very much appreciated! I believe now that when I updated the Kernel
(and 2 other packages) on my box and on my daughter's box, it was with
PUP and then later, I did a "yum update" to update everything else on
those boxes. 

If there is some place I can check in a yum database or RPM database on
her box, to verify the kernel version that's really installed (probably
the original one), please let me know where that is. Thanks much! Lanny

Well, firefox got updated, so perhaps your flash plugin is not present
in the "new" firefox directory.

[CentOS] images gone after yum update

2008-05-06 Thread Geert Batsleer
Hi,

yesterday I upgraded a centos 4.6 box via yum and now it seems that certain
pages, especially swf files stopped working.

Does anyone know if ImageMagick got broken  on x64? I don't see any other
package wich could have caused this problem.

kind regards,

Geert

[CentOS] Tunning EAP-TTLS with PAP

2008-05-06 Thread Sergio Belkin
Hi,
I have a freeradius server that is working well in  university. We use
EAP-TTLS and PAP protocols. Users from Windows can use Securew2. Users
from Linux and Mac OS X luckily have native support for EAP-TTLS and
PAP. (if you think is Off Topic, keep reading on). On Ubuntu I can use
the nm-applet for setting the connection up. But I'd want to find a
way to automatize it, that it finds the TTLS certificate and verifies
the server name (I didn't see this feature in Linux). Could you help
me to do this? (What tools/apps and file config should I look?)

Thanks in advance!

What's the status of this now?  I don't see it in the centosplus repo

there are a few things stuck in the testing repo, and were working on 
changing the way in which we do testing of packages so as to have them 
unstuck and either deleted or moved into stable ( and mirror.centos.org 
). So till that process is not done, I am not pushing anything new into 
testing.

Not yet, but we are working on it - there should be something there in
the next few days.


Will this be as part of the centosplus repository, or elsewhere?

If you have centosplus enabled, you will see it for sure!

If you proxy it, not with a Redirect, yes. It seemed he wanted just a
