you can run multiple glusterfsd instances on the same machine. the PID file
is only a mechanism which helps you write init.d scripts neatly. things you
need to take care -

1. if you are specifying pidfile, do not specify the same path for multiple
daemons
2. do not export the same backend directory with different glusterfsd
daemons.
3. take care to see to that both do not try to bind to the same tcp port
etc.

apart from that, the two daemons are oblivious to each other and they can
have same volume names defined as well.

Lastly, while I was able to make things work withing a

are they both using the exact same version? (to the patchset level)
