<BODY>
<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>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). <BR>
<BR>
A & B are both mounted and formatted as NTFS.<BR>
<BR>
One of the volumes is NFS mounted. <BR>
<BR>
Every couple of months or so we start getting tons of errors on the NFS mounted volume:<BR>

If we pull all the data off, destroy the volume, rebuilt it, and copy our data back, all works fine; for a while.<BR>
<BR>
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). <BR>
<BR>
Has anyone had a similar experience and be able to share some insight and knowledge on any tricks with NFS and OCFS2 volumes?<BR>
<BR>
Thanks in advance.<BR>
