In the GFS Shared File System, a setup for mounting and unmounting automatically at the time of system starting and ending differs from that of ext2, ext3, etc.
The mount options field of /etc/fstab must contain noauto in the GFS Shared File System. A setup of the automatic mount at system startup is determined by setting a parameter "mount options" to "noatrc" in /etc/fstab or not.
When noatrc is not described in the mount options field of /etc/fstab
The automatic mounting is performed by starting the fjsvgfsfsrm service on system startup.
When noatrc is described in the mount options field of /etc/fstab
The automatic mounting is not performed on system startup.
GFS Shared File Systems are automatically unmounted by stopping the fjsvgfsfsrm service when the system is shut down.
Note
It is necessary to set the management partition and the GDS volumes where partitions of the GFS Shared File System that will automatically be mounted are allocated to automatically become ACTIVE during system startup.
