Last night, we got some troubles with a GlusterFS mount. It's a replicate volume, and the 10.1.1.2 host was already down. The volume files weren't readable until I manually restarted the GlusterFS instance.
We'd like to understand what happened on this volume. Especially the "Server 10.1.1.1:6996 has not responded in the last 42 seconds, disconnecting." message. I can't figure out why the GlusterFS instance couldn't talk to itself.
Please help us.
This log is from 10.1.1.1 itself :
