On a different note - this is not the best way to create a replica 3 volume.
All you replicas are on the same host so if any one host goes down you lose
access to all the data on that replica set.

A better way is:

gluster volume create volume1 replica 3 transport tcp
ubuntu1:/work/work1/test-storage1 ubuntu2:/work/work1/test-storage1 
ubuntu3:/work/work1/test-storage1 ubuntu1:/work/work2/test-storage2
ubuntu2:/work/work2/test-storage2 ubuntu3:/work/work2/test-storage2
ubuntu1:/work/work3/test-storage3 ubuntu2:/work/work3/test-storage3 
ubuntu3:/work/work3/test-storage3
