Hi All,
First of all, thanks for the brilliant documentation at clusterlabs and
the alteeva.ca tutorials! They helped me out a lot.
I am relatively new to pacemaker but come from a Solaris background with
cluster experience, I am now trying to get on board with pacemaker
I have setup a 2 node cluster with a shared lun using pacemaker, cman,
dlm, clvmd and gfs. I have configured 2 stonith devices each to fence
either node.
The issue I have is that when i test an unclean shutdown of the 2nd
node, pacemaker goes ahead and fences the second node, but clvmd then
goes in to a failed state on node 1 and then it fences itself (shuts
down node 1).
I suspect it has something to do with me setting the on-fail=fence for
the dlm/clvmd services/RA's. DLM appears to be fine, but clvmd is the
one that goes in to a failed state. I suspect I have an issue with
timeouts here, but, being new to pacemaker I cannot see where, I am
hoping a new pair of eyes can see where I am going wrong here.
I am running, CentOS 6.5 in vmware, using the fence_vmware_soap stonith
agents. Pacemaker is at version 1.1.10-14, CMAN is at version 3.0.12.1-59.
I used the following tutorial to assist me in setting up dlm/clmvd/gfs2
on CentOS 6.5 (if it helps in the debugging)
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/7-Beta/html/Global_File_System_2/ch-clustsetup-GFS2.html
Any assistance, tips, tricks, comments, criticisms are all welcome
I have attached my cluster.conf if required, some node name obfuscation
has been done. If you need any additional info, please dont hesitate to
ask.
Thanks
