[Ocfs-users] Problems with OCFSTOOL after LUN Maintenance

[Tony Johnson]

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.

Subject: [Ocfs-users] Expanding (growing) Filesystemss


We want to expand the LUN's on our SAN. 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.
