[OpenAFS] Corrupted Volume

[Matthew N. Andrews]

Hello,
one of my user volumes died last week(needed salvage, with lots of
orphaned files) and I got the following from the Filelog about that
time:

Thu Feb 28 02:28:03 2002 CopyOnWrite failed: volume 536870939 in
partition /vice
pb  (tried reading 8192, read 0, wrote 0, errno 4) volume needs salvage
Thu Feb 28 03:08:52 2002 VAttachVolume: volume salvage flag is ON for
/vicepb//V
0536870939.vol; volume needs salvage

Thu Feb 28 04:06:34 2002 VAttachVolume: Error attaching volume
/vicepb//V0536871
029.vol; volume needs salvage; error=101


536870939 is the volume id for the volume with the corruption.

this is a redhat 7.2 afs server running openafs 1.2.2. kernel version
2.4.9-13 this is a uniprocessor i686 box

this has happened several other times with this same user, and at least
once for a couple of others.

any suggestions what might be causing this?
