Please note the following points when you start the node.
In RHEL7.1 or later version and RHEL8 environments, the following message may be output. However, it does not affect the starting operation.

Please note the following points when you stop the node.
Before stopping a node, please stop all the applications on a node accessing GFS Shared File System.
Use shutdown(8) to stop a node. If reboot(8), halt(8), or poweroff(8) is used to stop a node, GFS may not work correctly.
If you stop plural nodes including the node that operates the primary MDS, stop the node that operates the primary MDS at the end. Otherwise, it might take time to stop the nodes.
Information
If the GFS Shared File System is unmounted by sfcumntgl(8) on all nodes before the node is stopped when all shared nodes of the GFS Shared File System are stopped, the order of stopping the node need not be considered.
