[Pacemaker] How to tell pacemaker to start exportfs after filesystem resource

Thu Jun 23 23:06:00 UTC 2011

I fixed it.
Reason was in exportfs resource monitor. On startup it check was it already
started:
        # "grep -z" matches across newlines, which is necessary as
        # exportfs output wraps lines for long export directory names
        exportfs | grep -zqs
"${OCF_RESKEY_directory}[[:space:]]*${OCF_RESKEY_clientspec}"
But after node reboot nfs-state files are not in clean state for a reason
and it caused the monitor action to return 0 state that was a reason of
failed cluster.

I fixed it by moving /var/lib/nfs to share, and i placed pipefs in /var/lib
- so now exportfs, if /var/lib/nfs/etab isn't accessible, returns no exports
on startup.

Filesystem resource is working as designed.

Thanks all for help!
