The state of the group should be none. The numbers in the brackets are the node ID numbers of
the cluster nodes in the group. The clustat shows which node IDs are associated with which
nodes. If you do not see a node number in the group, it is not a member of that group. For example,
if a node ID is not in dlm/rgmanager group, it is not using the rgmanager dlm lock space (and
probably is not running rgmanager).
The level of a group indicates the recovery ordering. 0 is recovered first, 1 is recovered second, and
so forth.
• Connect to one of the nodes in the cluster and execute the cman_tool nodes -f command This
command provides information about the cluster nodes that you may want to look at. The following
example shows the output of the cman_tool nodes -f command.
[root@clusternode1 ~]# cman_tool nodes -f
Node Sts Inc
1 M 752
2 M 752
3 M 760
4 M 756
5 M 744
The Sts heading indicates the status of a node. A status of M indicates the node is a member of
the cluster. A status of X indicates that the node is dead. The Inc heading indicating the incarnation
number of a node, which is for debugging purposes only.
• Check whether the cluster.conf is identical in each node of the cluster. If you configure your
system with Conga, as in the example provided in this document, these files should be identical, but
one of the files may have accidentally been deleted or altered.
