Trying to use 7 DB servers we experienced some strange problems with AFS NT
clients (token loss and service failure). These problems disappeared when we
reduced the number of DB servers to 5...

Subject: Re: What is a quorum vote based on?
Jeff,
I believe it is the lowest working database server IP address.
Practical experience with upgrading/rebooting
database servers seems to verify this.
Caution: I once tried shutting down one db server
in a cell with two db servers. The result: mayhem.
With only one of two db servers running
instead of a quorum there was a quandry.
No sync site could be elected.
This leads me to believe that it is better to
configure an odd number of AFS database servers
to improve the availability of your cell.
Apart from the single db server case, this means
(with 3, 5, 7 or more) you are likely to have
enough working db servers for a quorum in
the event of database server outage.
