[OpenAFS] Backup DB issues, OpenAFS 1.4.1, Solaris 8,9

[Kevin Hildebrand]

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
