<p class=MsoNormal>Hi all. I have a 2 server configuration using drbd and
openais. This is a test/dev environment prior to proposing a production
rollout. My drbd config is below. The problem is that in an “uncontrolled”
poweroff of one of the servers, it will not come back online without user
intervention. I have narrowed this down to drbd apparently failing to repair
the corrupted filesystem (EXT2 which it needs to be for issues with our proprietary
software). When the node is powered back up, I can do a ps and grep for fsck,
and I can see that an fsck has been initialised for /dev/drbd0. However, there
are two issues here. Issue (1) By the time drbd has finished the fsck process,
the openais controlled services have timed out trying to start, and sit there
doing nothing until I reset the failcounts, and cleanup the resources. Issue
(2) is that the drbd triggered fsck does not actually seem to work as when I
carry out the cleanup process and try to start the services, it still fails. If
I do a manual fsck, it finds filesystem errors and repairs them, then all is
well. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, in summary, in my scenario, the drbd initiated fsck goes
through the motions but does not actually fix the filesystem, and secondly, by
the time the filesystem has been (supposedly) repaired, the openais services
have given up trying to start and sit there in a dead state.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
