PRIMECLUSTER Global File Services Configuration and Administration Guide 4.2 (Solaris(TM) Operating Environment)

15.1 Mount and unmount opportunity of the file system at the time of system starting and ending

For a GFS Shared File System, the setup for automatic mounting and unmounting during system startup and shutdown differs from ufs.

It is required to set no for the mount at boot parameter in /etc/vfstab for all GFS Shared File Systems. The option noauto controls the automatic mount during system startup.

When noauto option is not set in /etc/vfstab, the file system is automatically mounted during system startup. The automatic mount is performed by the script S81sfcfsrm which is executed during level 2 processing.

When noauto is set as a mount option in /etc/vfstab, the file system is not automatically mounted during system startup. If the file system is later mounted, it will be automatically unmounted during system shutdown. The script K09sfcfsrm unmounts file systems during system shutdown.

For the GFS Shared File system to mount file systems during system startup, the GDS volumes for the GFS management partition and the file systems must be automatically activated during system startup.
