Method for automatic cascading of file system mount points to an administrator
defined order during the import of a volume group
Disclosed is a method for enhancing a volume manager to propagate file system mount point information such that the file system mount points are added to the OS mount control files in a predetermined system administrator order during the import of volume group. Today, some volume managers establish mount information for physical file systems in the OS mount control files during the import of a volume group on a specific machine. However, system administrators must manually change the mount order on each machine if there is an implied mount order between file system in the same volume group or across different volume groups.
The proposed method would provide for the administrator to imbed cascading mount information within the file system meta data, the logical volume containing the file system, or the volume group containing the file system. The imbedded cascading mount information would indicate that one file system is mounted on a directory that is contained in a second file system. The proposed would allow file system commands to add information to the file system meta data, the underlying logical volume, or the containing volume group that would indicate the required mount ordering for mounting cascading file systems so that the proper mount order is established on import of the volume group(s) on any machine.
For example, the admin...
