stat() permission denied

[mike]

What would you suggest then for a central storage mechanism?

NFS and CIFS are the only I know of (that are free) - and CIFS is even
worse AFAIK.

I'm actually going to try to migrate my clients to use MogileFS for
their data, and then have the website code be done using rsync - so I
will hopefully be reducing NFS reliance as much as possible.

If you've got any ideas though I am all for it!
