File systems created on volumes in classes other than the root class (local classes and shared classes) cannot be mounted with the OS auto mount feature at OS startup.
This is because the OS auto mount process is executed before the GDS startup script is executed.
When including file systems created on volumes in classes other than the root class in the /etc/fstab file, be sure to describe the "noauto" option in the fourth field.
If the noauto option is not described, the following message is displayed at OS startup, and OS is started in emergency mode.
[ TIME ]Dependency failed for Local File Systems. |
Information
For Shared Classes
To mount or unmount file systems on volumes in shared classes when starting or exiting cluster applications, /etc/fstab.pcl file setting and Fsystem resource setting are necessary. When using GFS, see "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide." For details, see "PRIMECLUSTER Global File Services Configuration and Administration Guide."
Information
For Local Classes
To automatically mount or unmount file systems created on volumes in local classes on starting or exiting OS, create and set the script and unit files in order to satisfy the following conditions:
Execute the mounting process after all of the GDS service (fjsvsdx*.service) when starting OS.
Execute the unmounting process before all of the GDS service (fjsvsdx*.service) when stopping OS.
See
For details about GDS services, see "F.2 systemd Service Lists"
Similarly, to export file systems created on volumes in local classes to an NFS client, create and set the script and unit files in order to satisfy the following conditions:
Execute the mounting process before nfs-server.service when starting OS.
Execute the unmounting process after nfs-server.service when stopping OS.

For the startup script creation method, see "6.9 Volume's Block Special File Access Permission"
