Unsold Atari videogames dumped in a desert? iirc you have two choices here, either you'd need to stop running instance first and then run it in the console with -f -d1, or run clvmd -C -d2 to ask Need to restore entries in /dev for the file systems. Could this be related to clvmd doing a check when cman is up and running but clvmd has not started yet (As I understand from Vladislav's previous email). https://access.redhat.com/solutions/712563

I cannot start clvmd and I am frustrated because I cannot find a reason for it.

For example, if you extend a volume with lvresize and gfs_grow, the other nodes in the cluster will not be informed of the resize, and will likely crash when they try If the attr column shows something like "wz--n-" the clustering flag is off for the volume group. clvmd locked up and I keep getting 'kernel: dlm: volumegroup: reply from 2 no lock' - how do I fix it? Anyways, there is a big chance that stop will fail too, > and that leads again to fencing.

Why aren't changes to my logical volume being picked up by the rest of the cluster? However, I was testing dlm/clvmd outside of pacemaker control yesterday and my issue still persists, so I am wondering if there is something else amiss that I have not uncovered yet.

I was running it under pacemaker because it is a neat way of seeing dependant services.

To set the clustering flag on, use this command: vgchange -cy Download in other formats: Plain Text Powered by Trac 0.12.5 By Edgewall Software.Libravatar support by Tracvatar 1.9

When I remove dlm/clvmd from pacemaker control, then, I cannot immediatly see that the shared file system has a dependancy on clvmd and dlm.

Thanks for the explanation, this is interresting for me as I need a volume manager in the cluster to manager the shared file systems in case I need to resize for http://www.centos.org/forums/viewtopic.php?t=3117&start=10 Although it is not perfect, it should work much better for > you I will have a look around for this clvmd ocf agent, and see what is involverd in getting regards Lukas #1 grl, Dec 26, 2011 Last edited: Dec 27, 2011 grl New Member Joined: Oct 20, 2011 Messages: 15 Likes Received: 0 Re: [solved] Problems after updating cluster You may need to tell gdb that it shouldn't stop on some signals sent to the binary being debugged if it stops immediately after you type 'run' or 'cont' (f.e 'handle
