So, the first mount (on "piglet1") succeeds.  The second (on "piglet2")
returns immediately without mounting, and leaves this in the logs:

	gfs_controld[3035]: segfault at 0 ip 08051361 sp bfd88ae0 error 4 in gfs_controld[8048000+1d000]
	GFS2: fsid=: Trying to join cluster "lock_dlm", "piglet:test"
	lock_dlm: no mount options, (u)mount helpers not installed
	GFS2: fsid=: can't mount proto=lock_dlm, table=piglet:test, hostdata=

At this point, cman_tool nodes, status, and group_tool -v output from
piglet 1 are:
