Just now I got a hint on whats happening in the partition naming of
the Gluster.
In my server (n1), SATA disk is located in the IDE channel #1 as master whereas
the the same capacity SATA disk is located in IDE channel #0 as master in the
client node (n2). This difference in the location of hard disk is
letting the Gluster
to name the hard disk drive devices differently on the two nodes.
i.e. SATA disk is named as hdc in server and as hda in client.

Due to this difference the client is generating errors like
"Can' read from the /dev/hdc3: there is no devic ewith that name" and aborting.

If it is the actual reason behind the problem I have reported it is
really a bug in
Gluster.
