Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Reconciling major/minor

numbers for NFS shared

disks

This appendix includes the following topics:

■ Reconciling major/minor numbers for NFS shared disks

Reconciling major/minor numbers for NFS shared

disks

Your configuration may include disks on the shared bus that support NFS. You

can configure the NFS file systems that you export on disk partitions or on Veritas

Volume Manager volumes. An example disk partition name is /dev/dsk/c1t1d0.

An example volume name is /dev/vx/dsk/shareddg/vol3. Each name represents

the block device on which the file system is to be mounted.

In a VCS cluster, block devices providing NFS service must have the same major

and minor numbers on each cluster node. Major numbers identify required device

drivers (such as a HP-UX 11i v3 partition or a VxVM volume). Minor numbers

identify the specific devices themselves. NFS also uses major and minor numbers

to identify the exported file system.

Major and minor numbers must be verified to ensure that the NFS identity for

the file system is the same when exported from each node.
