Hadi,

Forget it. I suspect you would have to upgrade a whole load of libraries 
and if it were you doing it, you will break your system beyond recognition.

Hi Theo,
thank you for the reply. I have four disk in one LV. so yesterday I already
done pvmove the 2TB disk and it took time about 20 hours. I think the disk
is just start to fail and most part of the disk is still good, that's why
the pvmove process didn't take time that long.

Which intel chipset have you got?  Does OpenGL work, and if so, what's you

you have to install the following from SL 6.1:
  - latest kernel (kernel-2.6.32-131.12.1.el6)
  - kernel-firmware-2.6.32-131.12.1.el6
  - latest xorg-x11-drv-intel (xorg-x11-drv-intel-2.14.0-1) with 
dependencies (xorg-x11-drivers)
  - latest mesa packages: mesa-dri-drivers, mesa-libGL, mesa-libGLU 
(version 7.10-1 at the moment)
  - latest libdrm (libdrm-2.4.23-1)

Thank you very much for your help. Excuse me, do we have other sip
clients rather than ekiga that I can give them a try? The ekiga 2.0.2
is too old to work with my new Asterisk version on my centos 5.0  . I
will upgrade my other clients to centos 6.0 (as you told me) but for
unknown reasons this version of Asterisk does not work on my centos
6.0 but just my centos 5.0 so I need to keep my Asterisk server still
running centos 5.0 but I will upgrade all of my other clients to
centos 6.0  to make use of this new version of ekiga 3.2.6  .
Thank you again

Thanks a lot for this info, it's much appreciated.  When I get a chance (when
there's not someone logged in) I'll update mesa to match the versions you

[CentOS] CentOS and Scientific Linux Cern installations with FAI

2011-09-19 Thread lange
I'm very happy to announce, that FAI (Fully automatic Installation)
now can install and configure CentOS and Scientific Linux Cern
(SLC). You can use a Debian FAI server for installing CentOS version 5
and 6 or SLC 5 and 6.

As an example I've also built a FAI multi-distribution CD which
installs those three different Linux distributions with different
configurations. Get this ISO image from

http://fai-project.org/fai-cd/

This installation is very quick. I've done a CentOS 6.0 installation
(with graphical desktop) in 199 seconds (in a kvm instance on a
quad-core 3.2GHz, hard disk in RAM) and it only needs 490 seconds on
the real hardware when installing from CD.

A short description how to install CentOS or SLC via network
from your FAI server is described in this mail:
  https://lists.uni-koeln.de/pipermail/linux-fai/2011-September/009243.html

Feedback is always welcome. Please send your feedback to the linux-fai 
mailing list
 https://lists.uni-koeln.de/mailman/listinfo/linux-fai/

Best regards,
   Thomas, in behalf of the FAI team



About FAI:

FAI is a non-interactive system to install, customize and manage Linux
systems and software configurations on computers as well as virtual
machines and chroot environments, from small networks to large
infrastructures and clusters. 

Compared to kickstart, FAI is more flexible and includes a powerfull
class mechanism to build a configuration from multiple building
blocks. It also includes the features of cobbler.

The project was started in 1999 for the Debian distribution. Later
Ubuntu support was added and some time ago we start adding RPM
support.

[CentOS] questions about upgrading

2011-09-19 Thread Jon Detert
I'm pretty new to the task of upgrading CentOS or RedHat o.s.'s.  I'm more 
familiar with upgrading Debian based o.s.'s.  Here are my questions:

1) will yum ever upgrade the major version?  I understand that there is no 
upgrade path from v5.x to v6.x, but is that always the case?  e.g. was there an 
upgrade path from v4.x -> v5.x?  If yum is capable of doing so, what are the 
command-line arguments necessary?

2) can I upgrade a minor version to any other greater minor number, or only to 
the greatest?  E.g. if i have a v5.4 box, can i upgrade to v5.5 or v5.6, or 
only to v5.7 (currently the latest)?

3) if an upgrade delivers a new kernel, am I obligated to run it (i.e. will the 
old kernel remain installed, or will the upgrade remove the old kernel)?  If 
not, does the upgrade automatically update grub such that the new kernel 
becomes the default?  Will the upgraded box function properly without running 
the new kernel?

4) aside from when an upgrade includes a new kernel, how can I tell when a 
reboot is necessary?  I gather that a new glibc may require services to be 
restarted, but is a reboot strictly necessary?

5) is there a way to apply only the updates that were made for the given minor 
version you're currently at?  E.g. if I'm at v5.5, how can I only apply updates 
that were made prior to v5.6's availability?

Thanks,

Jon

[CentOS] eth enumeration order

2011-09-19 Thread Volker Poplawski
I have installed Centos 6 on a server with two NICs. It so happens that 
the NIC with the lower ARP adr is assigned 'eth1' and the NIC with the 
higher ARP 'eth0'. (Not sure if this a bug but it is at least inconvenient)

I have modified the udev rules in
/etc/udev/rules.d/70-persistent-net.rules
by swapping eth0 with eth1 in the NIC's rules.

However: the file gets changed on reboot. A third rule is automaticaly 
added for some reason, for one of the NICs which already has a rule. See 
below.
The system ends up with no network interface set up at all, because the 
init-script gets confused.

So
How do you specifiy the order in which NICs are enumerated?
or at least how to tell centos to stop messing with the 
70-persistent-net.rules?


Regards
.Volker



Contents of /etc/udev/rules.d/70-persistent-net.rules (arps anonymized):

(These are the two rules modified by me, assigning eth0/eth1 in 
ascending arp order)

# PCI device 0x8086:0x10d3 (e1000e) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="xx:xx:xx:xx:8f:ea", ATTR{type}=="1", KERNEL=="eth*", 
NAME="eth0"

# PCI device 0x8086:0x1502 (e1000e) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="xx:xx:xx:xx:8f:eb", ATTR{type}=="1", KERNEL=="eth*", 
NAME="eth1"

(This is the rule which gets automaticaly added on reboot)

# PCI device 0x8086:0x1502 (e1000e) (custom name provided by external tool)

Never has been a full release upgrade path - that's a bad idea, too much

Yum update *will* do that without a problem.

No, you're not. It will update /etc/grub.conf (a link to
/boot/grub/grub.conf), and the next time you reboot, it will default to
the new kernel. It does remove the oldest kernel, but leave (I believe) at
least three (current, and the last two).

Tune /etc/yum.repos.d to point to explicity subreleases is, I think, the
answer.

Yes if you configure the repositories in /etc/yum.repos.d accordingly
(i.e. use the vault).

Kernels are installed side by side. For the second question, see
/etc/sysconfig/kernel.

In theory you should be able to mix and match any components from the
same CentOS major release without problems, unless any of the release
notes say otherwise. Whether it's a good idea is a different matter.

New glibc requires a reboot. Upgrading other system libraries does
too, but I can't give a definite answer on the how to tell. ldd
/sbin/init indicates the libselinux and libsepol packages are other
candidates, but that's just one example.

See the answer to 2).

Other people will give you some flak for these questions as it's
generally recommended to run the latest version.

Sorry, I seem to have missed the start of this thread, and certainly don't
understand it. Certainly, all the systems I've upgraded to CentOS 6,
including the one I'm writing this on, are all booting off ext3 /boot
partitions.

Did the installer try to install /boot in the same partition as / ?

CentOS6/SL6 does support ext4 as a root device (My webserver is
currently doing so) but I still keep /boot as ext3.

OIC. So it needs an extra (ext3) /boot partition, as well as /.

It is there. I don't recall exactly how I got to it... I think I 
selected 'Customize' at the point where you can choose your packages and 
then I selected that I wanted to set the partitions myself. I got the 
same partition interface I've always gotten with CentOS installs... but 
it wasn't as obvious during the install process. It seems like some of

[CentOS] mdadm and drive identification?

2011-09-19 Thread David C. Miller
I have a server that has 16 drives in it. They are connected to a 3ware 
9650SE-16ML SATA RAID card. I have the card set to export all the drives as 
JBOD because I prefer Linux to do the reporting of drive and RAID health . I'm 
using mdadm to create a RAID6 with a hot spare. Doing this I can take the disks 
and put them on a completely different SATA controller/computer and still have 
the RAID intact. My problem is that I have no "for sure" way of matching a 
drive assigned to one of the /dev/sd[a-z]. Normally I could use a number of 
methods to match up what /dev/sd[a-z] is to a drives serial number. smartctl, 
hdparm, udevinfo, /dev/disk/by-uuid, or /dev/disk/by-id. However, the 3ware 
card obfuscates the drives from the OS and those methods don't work. The only 
way I know how to get a drives serial number is via the smartctl command like 
"smartctl -d 3ware,[0-15] -i /dev/twa0", but that does not tell me which 
sd[a-z] the drive is assigned to. Here is what I have tried.

Creating a single large partition with fdisk on each drive as linux autoraid to 
get a uuid. for some reason the OS assigns the same uuid and only one uuid to 
the last drive I partition from the 3ware card. Basically all drives on the 
3ware card have the same uuid..

Using the /dev/disk/by-id/.  For some reason the 3ware card does not always 
assign the same id to a drive after a reboot. 

Is there another easy way I can positively ID a drive by serial number and the 
/dev/sd[a-z] that mdadm sees? 

Thanks.
David.

Mail delivery can still work with sendmail turned off. The daemon is
just there to receive mail.

This guy explains it better than I can:

http://www.deer-run.com/~hal/sysadmin/sendmail.html

There's no reason to turn the MTA on unless you're running a mail
server. Non-mail servers should just have a cron job flushing the
submission queue just in case, but the MTA itself doesn't need to run.

I'm sorry I don't follow you here?

I'm fairly certain that 6.1 will include both 6.1 security/bug updates AND 
security/bug updates that have been released up to the beginning of the 6.1 
release cycle, minus several that where released during the C6.1 release cycle. 
Security updates and bug fixes are intermingled without being able to

It's not the security updates that prevent me from moving to 6.0 right now, but

those pesky .0 blues as you call them were clearly there - see other
threads about video issues, etc.

I guess the point I was trying to make without being excessively blunt
is that the track record of timely releases for CentOS 6.x (any release)
and the track record of timely security updates (none) should really
cause any one to pause before installing any version of CentOS 6 - even
if 6.1 and all of the current security updates were released tomorrow.

[CentOS] LVM lvresize/lvextend requires some space in /etc to grow a logical volume?

2011-09-19 Thread Johnny Tan
Side note:

In CentOS-6, I noticed a new option in lvresize / lvextend:

   -r, --resizefs
  Resize underlying filesystem together with the logical
volume using
  fsadm(8).

Nice. Two steps (lvresize and resize2fs) can now be combined into one!
Works great.

But that has nothing to do with my question, just thought I'd share
the discovery.

==

Anyway, here's the real issue with LVM, at least in CentOS-6:

[root@jttest ~]# df
Filesystem   1K-blocks  Used Available Use% Mounted on
/dev/mapper/vg_main-lv_root
   1548144   1548144 0 100% /

[root@jttest ~]# lvextend -L 2G /dev/vg_main/lv_root
  /etc/lvm/archive/.lvm_jttest.pp.local_5523_51321310: write error
failed: No space left on device
  Volume group "vg_main" metadata archive failed.
  /etc/lvm/cache/.cache.tmp: write error failed: No space left on device

So I can't extend a logical volume if there's no space in /etc?

Granted, I only need to delete like 2k worth of files in the same
logical volume as /etc to make the above work, but I don't recall
lvresize or lvextend requiring space in /etc to do a resize. Has this
always been the case? I don't have any 5.x servers handy to test this
with. Can anyone verify?

If this is new, this seems less-than-ideal. /etc itself rarely fills
up, so, in theory, I could make it its own LV, but that's even less
ideal. For now, I'll stick to deleting just enough to do the
extend/resize.

[CentOS] reading vdump files?

2011-09-19 Thread Smithies, Russell
I have a lot of data in some vdump files backed up from a Tru64 system that I 
now need to recover to a Centos server.
We no longer have any servers running Tru64, is there any way to 
extract/convert them on a "standard" linux system?
Ideally converting in bulk to a tar would do.

Any ideas?

Do i read that correctly and 1548144 1K Blocks are about 1,5G of Root

If not, for production use, install a tool which gives you a warning

lvm tries to be helpfull if you ran into a power failure and can then
recover due his tmp files in /etc.

You will have the same problem, i think this procedure is the same in

This is why the older unix guys always seperate stuff from / which could
fill up the root file system. ;)

Many LVM modifications make a backup of the lvm metadata, which
typically resides in /etc/lvm.  You might try the -A n switch to
disable the automatic backups (after strongly heeding the advice
in man lvm; but as you said, on a test system, it's fine to play
with).  On a production system, if your / fills to 0 available blocks
you've probably got bigger problems.  :)  So I imagine it's probably not
a problem the LVM developers are too worried about (i.e., they may feel
that the -A switch is sufficient to handle it).

That did the trick:

[root@jttest~]# lvresize -L 2G /dev/vg_main/lv_root
  /etc/lvm/archive/.lvm_jttest.pp.local_1416_1029753972: write error

  Extending logical volume lv_root to 2.00 GiB
  WARNING: This metadata update is NOT backed up
  Logical volume lv_root successfully resized
  /etc/lvm/cache/.cache.tmp: write error failed: No space left on device

(And the subsequent resize worked too.)

Thank you for pointing out the -A flag (missed the fine print of
common options being in man lvm).

As you noted, I would probably never run into this situation in a
non-testing environment and, if I did, would have much bigger
problems. This probably explains why I never saw it previously. Good
to know.

Thanks
