gfs1 would not have all the peers configuration until and unless it
becomes a node in the cluster. Here the peer handshaking between gfs1 &
gfs3 did not happen completely, some how gfs3 didn't receive a response
which it was expecting from gfs1. Can you check whether glusterd
instance of gfs1 some how went down at the point when peer probe was
executed?> Last lines of the debug log on gfs1 looks like this:
