[Ocfs-users] Problems with OCFSTOOL after LUN Maintenance
In installing 10g\RAC we hit an issue that has been indentified as a bug with CRS where the cluster locking files cannot be implemented under OCFS. Supposedly they work fine when implemented as Raw Devices. We needed to reclaim some space from existing LUN's to create the raw devices as we had expected to able to put all Oracle related files under OCFS (Yes, we belived the hype). This required us to drop and recreate the LUNs that are to be used under OCFS. As a result OCFSTOOL does not recognize the new LUNs that were created. Also, any new LUNs that have been created are not being seen by OCFSTOOL. Oracle support on this issue has been expectedly poor. Has anyone else seen and issue like this ? Thanks in advance. ------------------------------------------------------------------------ ----------------------------------------------- Tony Johnson Email : tony_johnson@trimble.com Database Administrator Voice : ( 480 ) 682 - 0849 Trimble Navigation Cell : ( 480 ) 570 - 0215 7408 W.

I have expanded the LUN's, rebooted the hosts, now want the hosts to mount up the larger LUN, but they still see the original size. How risky is it to use tuneocfs to grow the filesystem after the expanded LUN is presented to the host? I was unable to find anything outside the man page for it.

those things are fixed in 1.0.11, so if you run previous ocfs then upgrade that bug is fixed.

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.
