SOS: Production VM not starting!
by Nikolaos Milas 12 Dec '12

12 Dec '12

I am using a VM with CentOS 5.8 x86_64 under KVM. I only have console access to the VM through a virtual console (web based). Tonight, after a routine "yum update", I did a "shutdown -r now" due to kernel update and the VM won't start. See console screenshot vm1.png: https://vmail.noa.gr/files/vm1.png There is an error (which I haven't seen before): type=1404 audit (...): selinux=0 auid=... ses= ... (see vm1.png above) (The system cannot load even with the old kernel; the same error occurs.) Note that SElinux is disabled on this system. I booted in rescue mode, and auto mount was unsuccessful (see https://vmail.noa.gr/files/vm2.png) The log of the rescue process shows some error (see https://vmail.noa.gr/files/vm4.png) However, later I successfully mounted it using: mount -t ext3 /dev/vda3 /mnt/sysimage I then did a umount and: fsck.ext3 /dev/vda3 which found it clean (see https://vmail.noa.gr/files/vm3.png) What is wrong there? Can you please guide me on how to make it work again? This is a production ftp machine. Please help to revive. Thanks, Nick

I apparently missed it when doing the config files for CentOS 6.3. So, all 6.3 cplus kernels have that option disabled. :( I reopened the bug 5709. Could you add a note there so we can track this issue? I will try to get this corrected on the next kernel update. Akemi

KDE login screen configuration problems

Sorry to be so slow in responding. I've done what you suggested. I created /etc/sysconfig/desktop and entered "$DISPLAYMANAGER=KDM". I rebooted but there was no change. GDM is still being used. Any other suggestions? mw ======================== Just create the file /etc/sysconfig/desktop and put in it: DESKTOP=KDM I believe it's DESKTOP - you can dbl check /etc/X11/prefdm Sent from my phoneMike Watson <mikew at crucis.net <http://lists.centos.org/mailman/listinfo/centos>> wrote:The last reply to this subject said to modify /etc/sysconfig/desktop to change GDM to KDM. This would then enable the KDE login screen instead of the default Gnome. However, when I checked my CentOS 6.3 system, there was no such file, no /etc/sysconfig/desktop. I've not been able to find any method to enable KDE login in 6.3. The method mentioned in the earlier reply was for CentOS 5, not 6.

Wacom hotplug Xorg crash
by James Pearson 10 Dec '12

10 Dec '12

We're seeing a number of Xorg crashes with CentOS 6.2 when using a Wacom tablet shared between two machines (the other machine is running Windows) via a KVM Xorg crashes after switching the KVM back to the CentOS box I've tried googling for this issue - and have found: https://access.redhat.com/knowledge/solutions/148183 Which has a similar backtrace (although not identical) to ones we are seeing (see below) - but no further info is given on that webpage - but appears to indicated that more info might (?) be available if I have a Red Hat Subscription login - which I don't ... Would it be possible for someone that does have access to let me know if there is any more Red Hat Knowledge Base information about this issue?

what might cause iSCSI connection 1:0 error ISCSI_ERR_CONN_FAILED
by Götz Reinicke - IT Koordinator 10 Dec '12

10 Dec '12

Hi, I do have a centos 6.x server which accessed two different iscsistorages for a long time without any trouble. The storage-connection is done by a separate NIC and VLAN. The LAN access is on an other NIC. This weekend something broke and I don't have any clue what might be the problem or what caused it. The storages where mounted RO. In /var/loge/messages there are lot of messages; so from dmesg: Dec 10 17:13:21 richter kernel: connection3:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4324582419, last ping 4324587419, now 4324592419 Dec 10 17:13:21 richter kernel: connection3:0: detected conn error (1011) Dec 10 17:13:22 richter iscsid: Kernel reported iSCSI connection 3:0 error (1011 - ISCSI_ERR_CONN_FAILED: iSCSI connection failed) state (3) From dmesg: connection1:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4324597423, last ping 4324602423, now 4324607423 connection1:0: detected conn error (1011) I restarted the server and the filesystems are back online RW, but there are still that messages.

ionice...
by John Doe 10 Dec '12

10 Dec '12

Hey, anyone has some successful experience with ionice? I tried it with 'idle' (-c 3) parameter. When I did a quick test (find /), it seemed to work with frequent pauses (I guess waiting for idle). But when I used it on my big tar, it made it worse than without... which seems counter-intuitive. Thx, JD
