It mounts the video directory of the master backend through NFS so that the recordings are written directly to the main video storage directory (which is an XFS file system on a 64-bit Fedora 8 box). Here is the line from fstab mounting the master backend directory:

Output from /proc/mounts:
192.168.1.50:/data/video /video nfs
I see a "vers=2" in there along with a "mountvers=1", does that mean
that it's mounting as version 2 NFS? I'm not sure how to check the
version of NFS running on the server and client, but the client is a
Fedora 10 machine and the server is Fedora 8, my assumption is that
both of these OSs were put out well after NFS v3 was out. How can I
enforce a v.3 mounting if not through the "nfsvers=3" command?
On the issue of the nfs log, I didn't create the export with logging
enabled. I can go back and do that now, but I won't have logs for a
Thanks for the help.
