[Ocfs-users] Problems with OCFSTOOL after LUN Maintenance

[Sunil Mushran]

Pre 1.0.11, ocfs had issues with crs. 1.0.11 was released in march.
Since then, we have not heard of any issues.

ocfstool just scans the devices in /proc/partitions, and then looks for
the appropriate signature to identify ocfs volumes. So, if it is not
listing the devices, check /proc/partitions. Are all the devices there?
You can also use mounted.ocfs to see if the volume is ocfs or not.

strace -o outfile octstool
should give us some clues as to what the issue is.
