[Gluster-users] GlusterFS 3.1.1 - local volume mount

[Jacob Shucart]

Joshua,

That is correct.  If at the time you try to mount the volume the server is
down, then you won't be able to mount the volume in the first place.  If
this is a concern, you can set up something like ucarp to handle IP
failover so your mount command will work, but usually mounting is
something that is not done frequently, right?  Or you could have a round
robin DNS entry that points to all of your storage nodes so that your
mount command is essentially hitting a different server each time.

But if the server listed in the mount command is down *when the client 
attempts to establish the connection* (i.e. at mount time), then the 
client won't be able to discover the rest of the cluster and the mount 
will fail.  Right?
