Ah, found the problem. It appears that OpenAFS 1.4.1 does not properly
handle the -servers argument to buserver. Our configuration was
specifying all three servers as part of the bos configuration, i.e.,
buserver -servers server1 server2 server3. If you specify things this way
with 1.4.1, it not only ignores the specification, but it causes the
server to run as a standalone. The 'corruption' we were seeing was
because each of our servers was considering itself the only master.
Removing the '-servers' argument seems to have solved the problem.
I will open a bug report about the apparently mis-handled argument.
Thanks,
Kevin
