[Ocfs2-users] Issue with OCFS2 mount

[Rory Kilkenny]

We have an HP P2000 G3 Storage array, fiber connected.  The storage array
has a RAID5 array broken into 2 physical OCFS2 volumes (A & B).

A & B are both mounted and formatted as NTFS.

One of the volumes is NFS mounted.

Every couple of months or so we start getting tons of errors on the NFS
mounted volume:

If we pull all the data off, destroy the volume, rebuilt it, and copy our
data back, all works fine; for a while.

This issue does not happen on the non NFS mounted volume. I am currently
assuming the issue is with NFS and how we have it configured (which to the
best of my knowledge is default).

Has anyone had a similar experience and be able to share some insight and
knowledge on any tricks with NFS and OCFS2 volumes?

Thanks in advance.
