Re: [Ocfs2-users] ocfs2 processes that need to be up

[Madhu Velukur]

Srinivas - To validate ocfs2 process and setup on any given set of cluster nodes, we do following validation to make sure ocfs2 is working as expected before doing clusterware install: ------------------------------------------------------------------------ # /sbin/lsmod | grep ocfs ocfs2                 351172  2 debugfs                14216  2 ocfs2 ocfs2_dlmfs            27144  1 ocfs2_dlm             199176  2 ocfs2,ocfs2_dlmfs ocfs2_nodemanager     159360  26 ocfs2,ocfs2_dlmfs,ocfs2_dlm configfs               28044  2 ocfs2_nodemanager jbd                    59609  2 ocfs2,ext3 # ps -efw | grep ocfs root      4232    12  0  2007 ?        00:00:00 [ocfs2_wq] root      4233    12  0  2007 ?        00:00:51 [ocfs2vote-0] root      4238    12  0  2007 ?        00:00:00 [ocfs2cmt-0] root      4243    11  0  2007 ?        00:00:00 [ocfs2vote-1] root      4248    11  0  2007 ?        00:00:00 [ocfs2cmt-1] -------------------------------------------------------------------------- >From past few weeks, we are observing a waived  behavior on ocfs process out, it shows multi-digit for each daemon process and this count is getting increased for each node reboot. We do node reboot [as and when required] as WA to overcome bug #5960630 that we had discussed in past. Can you let know whether below o/p is expected behavior? # ps -ef | grep ocfs2 root      4309    12  0 Apr15 ?        00:00:00 [ocfs2_wq] root     19441    13  0 05:59 ?        00:00:00 [ocfs2vote-52] root     19446    12  0 05:59 ?        00:00:00 [ocfs2cmt-52] root     19454    11  0 05:59 ?        00:00:00 [ocfs2vote-53] root     19459    11  0 05:59 ?        00:00:00 [ocfs2cmt-53] Above problem is observed on following farm nodes - stbcf01, stbcf03, stbcf05, stbcf07, stbcf11, stbcf13, stbcf15, stbce09, stbce13 Thanks, Madhu Krishna Krishnapriyan wrote: Hi, Any information on the following situation will be appreciated. I am not on the ocfg2-users mailing list. So, please reply to me directly. We run our install rests on the farm rac clusters and we have been checking whether ocfs2 is up by looking for processes [ocfs2vote-x], [ocfs2cmt-x], [ocfs2vote-x], [ocfs2cmt-x],[ocfs2_wq] where x is a digit. Our observation was that x was usually 0 but sometimes a larger digit. Of late we have been noticing that x appears to be a larger multi-digit number. Questions: What is the significance of the specific digit/number x? Is it supposed to be within some range for ocfs2 to be working correctly? Rather than doing a check of the processes to verify that ocfs2 is up, is there a command that can be run, that verifies the health of ocfs2? Thanks, --Krishna
