--- Comment #2 from Fang Huang <fanghuang.data at yahoo.com> ---
This is what I did:
-----------
$ command line;
# comments I added
bdfs-node1 is the hostname
Two bricks were used. One used the system storage mounted on "/". The other
used /dev/sdc1 mounted on "/data/br1".
-----------

$ gluster v create worm-test bdfs-node1:/data/br0 force
$ gluster v set worm-test worm on
$ gluster v start worm-test
$ mkdir client
$ mount -t glusterfs bdfs-node1:worm-test ./client/
$ export LANG=en_US
$ cd client/
$ for i in `seq 0 9`; do dd if=/dev/zero of=./dummy_$i bs=1M count=1; done
$ gluster v add-brick worm-test bdfs-node1:/data/br1/br1 force
$ gluster v rebalance worm-test fix-layout start
$ gluster v rebalance worm-test start force
$ gluster v rebalance worm-test status
# To make sure the progress completed.

$ for i in `seq 10 99`; do dd if=/dev/zero of=./dummy_$i bs=1M count=1; done
$ ls /data/br1/br1/
