The GFS Shared File System requires, in addition to the volumes that shares the file system, one GDS Shared volume that is exclusively for the management partition for each cluster system. Even when using two or more file systems, the number of required management partitions is one.
Specify a volume size of at least 40 megabytes for the management partition.
See
For details on how to set up the GDS Shared disk system, see "PRIMECLUSTER Global Disk Services Configuration and Administration Guide."
Note
A setup of the volume which creates the management partition should set to "shared" the type of a disk class with which volume belongs. Also, all the nodes that share the GFS Shared File System must be specified as the scope of the disk class to which the volume belongs. Moreover, the settings must be such that the volume is automatically activated when the node is started.
Set "no" to [ Exclusive use ] of the disk class use including the volume where the management partition exists in.
If a disk class that includes volumes with management partitions is set in a GDS resource of a cluster application by mistake, the volume will not enter ACTIVE automatically during node startup. Therefore, the GFS Shared File Systems does not work.
