Perl script: storage_cluster
Usage:
$ ./storage_cluster [number of server nodes]
Example:
$ ./storage_cluster 4 Starting Storage Cluster with 4 nodes.. Configuring node #0... up! (dir:/home/cfs0 - port:6996) Configuring node #1... up! (dir:/home/cfs1 - port:6997) Configuring node #2... up! (dir:/home/cfs2 - port:6998) Configuring node #3... up! (dir:/home/cfs3 - port:6999) Mounting partition... glusterfs:28026 on /home/toad/gfs/glusterfs type fuse (rw,allow_other,default_permissions)

#! /usr/bin/perl -w
