[OpenAFS] Re: heartbeat and OpenAFS

[Brent A Nelson]

Cool.  I shutdown the bosserver on one machine, hexedited the sysid file
to match the UUID of the other server, did "vos changeaddr -remove" on the
addresses listed under the old UUID (from "vos listaddr -printuuid"),
restarted bos, failed-over the file server, and it worked!

The server-side fails over very quickly (a few seconds, depending on how
long salvage takes), but active clients do experience some sort of timeout
of a couple of minutes or so, even with the failover IP address... Any
suggestions on how I might further minimize this delay?

Thanks,

Brent

making the uuid the same on both machines would solve the problem you're
having.
