Abstract

Disclosed is a method for enhancing a volume manager to propagate Network File System* (NFS) information during import of a volume group, which would allow NFS mount information for a file system to get established during a volume group import. Today, volume managers can establish mount information for physical file systems in /etc/filesystems on a UNIX** based machine as the file system commands are aware of the underlying volume manager. However, system administrators must manually propagate NFS mount information to all servers that would serve this file system.

Method for extended NFS file system attributes to a volume manager

Disclosed is a method for enhancing a volume manager to propagate Network File System* (NFS) information during import of a volume group, which would allow NFS mount information for a file system to get established during a volume group import. Today, volume managers can establish mount information for physical file systems in /etc/filesystems on a UNIX** based machine as the file system commands are aware of the underlying volume manager. However, system administrators must manually propagate NFS mount information to all servers that would serve this file system.

The proposed method would provide for the administrator to imbed NFS mount information within the physical file systems containing logical volume, or volume group. After the administrator changes the NFS mount information for a file system by adding information to /etc/exports, the administrator would run exportfs to push this information into the NFS kernel extension. The exportfs command would be enhanced, and it will determine both the underlying file system and logical volume for a specific mount point. Next, it would call a volume management command which will store this NFS mount information within some volume group meta data area. The volume manager now enhanced, and a volume group is imported on the machine. The NFS mount information that was saved in the volume group meta data area is now stored in the appropriate NFS export fil...
