Yeah they work fine . This started when we had a network problem.

I see this:

dlm_tool lockdebug rgmanager 

can't open /sys/kernel/debug/dlm/rgmanager_locks: No such file or directory

"dlm_tools ls lockdebug" you mean?

"dlm_tool ls" returns

Well I have a qdisk with vote 3 . Thats why it is 6.

Here is the log. I see some GFS hung but no issue with GFS mounts at this time.


I am seeing this at clumond.log not sure if this is related and what is it.

where is your log?

I don't think this is the problem, but anyway from your config i saw <cman expected_votes="6"......

from man cman

Expected votes
       The  expected  votes  value  is used by cman to determine quorum.  The cluster is quorate if the sum of votes of existing members is
       over half of the expected votes value.  By default, cman sets the expected votes value to be the sum of votes of all nodes listed in
       cluster.conf.  This can be overriden by setting an explicit expected_votes value as follows:

If you remove this expected_votes="6", the cluster will set this parameter to 3

from your previous outpout of cman_tool services

Oh. How did you see that?

Here is the cluster.conf http://pastebin.com/DveLMGXT

Hi,
We had some network problem the other day and today I noticed the clusvcadm commands are not working. For example: it does not want to stop the service, migrate a vm etc etc. On one of the nodes clustat does not show any running services. I should restart the rgmanager?

This is RHEL 5.

Thanks
Paras.
