Thanks Rainer,

I think the issue was that during system "updates" we switched over to =
SLC
from SL (since the system is at CERN), not customizing to prevent =
switching
to the CERN OpenAFS RPMS when we did that.  The OS has been upgraded a =
few
times while we just keep the /vicepb partition and I believe the =
original
AFS was the SL based one.=20

After getting a few emails offline I realized that this might be similar =
to
an issue we had in the past mixing SL and SLC OpenAFS server software =
(as
you note the CERN server has customizations for CERN use).  =20

I reverted the OpenAFS to the SL versions on atums2 and things seem to =
be OK
again:

That's a bad idea, we've used the volume "magic" for staging purposes in =
the
past!

Don't mix, and certainly don't switch with existing data.
