Starting PFS I/O Daemons

PFS requires an I/O daemon to be running on each I/O server node. These daemons start automatically when node(s) on which they reside boot. However, if you want to start an I/O daemon on a newly created I/O server without rebooting, start the daemon manually on that node.

# /etc/init.d/sunhpc.pfs_server start

Once the daemons are running, execute the mkfs and mount commands in each parallel file system. For example, if cities is to be a 512-Mbyte file system.

# mkfs cities 512M# /opt/SUNhpc/bin/pfsmount cities

Alternatively, after executing the mkfs command, do the following on every node in the cluster.

# mount cities

The parallel file system cities is now ready to use.

Once mkfs has been run on a file system, You should not attempt to change its configuration attributes in the CRE database. Doing so could result in the loss of file system contents.
