IBM General Parallel File System for AIX: Administration and Programming Reference

Mounting a file system

You must explicitly mount a GPFS file system if:

1. This is the first time the file system is being mounted after its creation.
2. You specified not to automatically mount (-A no) the file system when you created it.

If you allowed the default value for the automatic mount option (-A yes) when you created the file system, then you do not need to use this procedure after restarting GPFS on the nodes.

For information on mounting a file system with quotas enabled, see the IBM General Parallel File System for AIX: Concepts, Planning, and Installation Guide and search for quota system files.

To mount a GPFS file system, enter:

mount device

where device is the file system mount point. For example, to mount the file system fs1, enter:

mount /dev/fs1
 

Mounting a file system on multiple nodes

In an SP environment, to mount a GPFS file system on all nodes in a GPFS nodeset, you can issue a dsh command, if you have created a file listing all of the nodes as suggested in the IBM General Parallel File System for AIX: Concepts, Planning, and Installation Guide and search for files to ease the installation process in an SP environment. For example, if gpfs.nodes is the file listing all of the nodes and the file system fs1, enter:

WCOLL=/tmp/gpfs.nodes dsh mount /dev/fs1

In an HACMP environment, if you have created a file listing all of the nodes in your nodeset (see the IBM General Parallel File System for AIX: Concepts, Planning, and Installation Guide and search for files to ease the installation process), you can issue a remote shell command to mount your GPFS file system on all of the nodes. For example, if gpfs.allnodes is the file listing all of the nodes and the file system is fs1:

#!/usr/bin/ksh
for node in $(cat /tmp/gpfs.allnodes) 
do
rsh $node mount /dev/fs1
done
