[Gluster-users] gluster brings down freebsd network interface

[Wei Dong]

Yes, only the ethernet interface connected to the gluster machines is 
down and everything else works.  There's a "em0 watchdog timeout" line 
on the screen and log, and even if I restart the network subsystem the 
interface remains down.  This is not a bug of glusterfs though, but 
glusterfs must have done something special at startup to trigger the bug.

Also I'm wondering if it's possible to run only one instance of 
glusterfsd to serve both as a server and as a client.

Thanks,

- Wei
