Comment 1 Lakshmipathi G 2010-09-03 06:34:55 EDT
created two volumes as -
gluster volume create DHT4 10.192.134.144:/mnt/d1 10.214.231.112:/mnt/d1 10.198.110.16:/mnt/d1 10.192.141.187:/mnt/d1
gluster volume create AFR4 10.192.134.144:/mnt/a1 10.214.231.112:/mnt/a1 10.198.110.16:/mnt/a1 10.192.141.187:/mnt/a1
