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:<br>
<br>
------------------------------------------------------------------------<br>
# /sbin/lsmod | grep ocfs<br>
ocfs2 351172 2 <br>
debugfs 14216 2 ocfs2<br>
ocfs2_dlmfs 27144 1 <br>
ocfs2_dlm 199176 2 ocfs2,ocfs2_dlmfs<br>
ocfs2_nodemanager 159360 26 ocfs2,ocfs2_dlmfs,ocfs2_dlm<br>
configfs 28044 2 ocfs2_nodemanager<br>
jbd 59609 2 ocfs2,ext3<br>
<br>
# <b>ps -efw | grep ocfs</b><br>
root 4232 12 0 2007 ? 00:00:00 [ocfs2_wq]<br>
root 4233 12 0 2007 ? 00:00:51 [ocfs2vote<b>-0</b>]<br>
root 4238 12 0 2007 ? 00:00:00 [ocfs2cmt<b>-0</b>]<br>
root 4243 11 0 2007 ? 00:00:00 [ocfs2vote<b>-1</b>]<br>
root 4248 11 0 2007 ? 00:00:00 [ocfs2cmt<b>-1</b>]<br>
--------------------------------------------------------------------------<br>
<br>
>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?<br>
<br>
# ps -ef | grep ocfs2<br>
root 4309 12 0 Apr15 ? 00:00:00 [ocfs2_wq]<br>
root 19441 13 0 05:59 ? 00:00:00 [ocfs2vote-<b>52</b>]<br>

Above problem is observed on following farm nodes - stbcf01, stbcf03,
stbcf05, stbcf07,
stbcf11, stbcf13, stbcf15, stbce09, stbce13<br>
<br>
Thanks,<br>

<br>
Any information on the following situation will be appreciated. I am
not on the ocfg2-users mailing list. So, please reply to me directly.
<br>
<br>
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.
<br>
<br>
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?
<br>
<br>
<br>
Thanks,
<br>
