[OpenAFS] Weird Quorum Issues

[Aaron Stanley]

I was away from my cluster for two days and when I got back I noticed some
very odd behavior with volumes locking for replication and not getting
unlocked like normal.  When I would issue a vos unlock for the volumes that
were locked I got strange errors like:

u: No Quorum Elected
Error in vos unlock command

If I continued to re-run the command, eventually the volume would unlock.  I
noticed this behavior with vos create, vos release, and vos backup as well.

I ran a udebug on all three of my vl servers for both ports 7002 and 7004.
On the primary (largest) fileserver, the output would waffle between the
normal "I am sync site" and the not normal "I am not sync site".  I thought
at first that it might be a network issue, but pings between servers was
great and bandwith was not an issue.

At this point, I don't know what could be causing the primary server to,
sort of, lose its quorum every second or so, so I'm hoping someone on the
list might be able to point in a direction.  I didn't notice anything
strange in the logs, but perhaps I'm looking in the wrong place so any hints
there would be appreciated.

I tried culling the list archives for a similar problem report, but I
couldn't find anybody describing a situation where sometimes the quorum was
present, but then a second or two later it was gone.

I truly appreciate any ideas and/or help.  Thanks!
