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.
