hi all,
glusterfsversion 3.0.0
replication: server-side-replication
we have 2 glusterfs server with glusterfs v 3.0.0 and one
clienthost with glusterfs v3.0.0. Now we have one partition which
contains office-files and short videos.
We simulate a serverfailture on gfs-01-01 (rcnetwork stop; sleep
300; rcnetwork start). After rcnetwork stop on gfs-01-01 we see at
the client host at mountpoints
/GFS/office-data02': Transport endpoint is not connected => we
cant do anything on this partition. If gfs-01-01 comes back online
the partition is accessable. same situation at gfs-01-02
but here if we make a df the clienthost does nothing. if gfs-01-02
is back online the partition is again accessable.

Did we do anything wrong? Are the volfile wrong? This couldnt be a
normal behavior?

Note that the first entry here is posix, not posix-remote. This order
should be maintained as replicate uses the children as lock-servers in
the same order as they are given for subvolumes option. Changing the
order results in different replicates (server1 and server2) using
different lock-servers thereby causing race conditions.
