+.SH "SERVICES" OUTPUT
+
+Lists the gfs, dlm, fence and rgmanager (user) groups registered locally
+with cman.  Cman manages the membership of each group, and coordinates
+their recovery.  The group name, global ID, local ID, State and Code are
+shown for each group.  The nodeid's of the current group members are shown
+on the second line within "[ ... ]".
+
+The following details relate to the internal cman group states and can be
+useful for debugging.
+
+\fBGroup states\fP include:
+.TP 8
+.I run
+normal operation, no transition in progress
+.TP
+.I join
+local node is joining the group
+.TP
+.I update
+local node is adding/removing another node to/from the group
+.TP
+.I recover
+group is being recovered from the failure of a member
+
+
+.TP 0
+\fBRecovery codes\fP indicating the local state of recovery:
+
+.TP 2
+1
+STOP the group has been told to stop in preparation for a recovery
+.TP
+2
+START the group has been told to do recovery
+.TP
+3
+STARTDONE the group has finished recovery locally
+.TP
+4
+BARRIERWAIT the group has finished recovery locally and is waiting for
+remote nodes to finish their recovery, too
+.TP
+5
+BARRIERDONE recovery for the group has completed on all nodes, and all
+nodes have joined the completion barrier
+
+.TP 0
+\fBEvent codes\fP related to nodes joining and leaving the group.  There
+are two forms these codes can take:
+
+.TP 0
+S-se_state,se_flags,se_reply_count
+.TP 4
+"S" indicates that the local node is joining or leaving the group.
+.br
+se_state is the state of the sevent, see SEST_* in sm_internal.h.
+.br
+se_flags are flags in the sevent, see SEFL_* in sm_internal.h.
+.br
+se_reply_count is the number of ack's received for the sevent.
+
+.TP 0
+U-ue_state,ue_flags,ue_nodeid
+.TP 4
+"U" indicates that the local node is processing the join or leave of
+another node.
+.br
+ue_state is the state of the uevent, see UEST_* in sm_internal.h.
+.br
+ue_flags are flags in the uevent, see UEFL_* in sm_internal.h.
+.br
+ue_nodeid is the node whose join or leave the uevent relates to.
