Hi Karthik,

Please provide the following info, I see there are errors unable to connect to
port and warning that transport point end connected. Please find the complete
logs below.
kindly suggest.

Task Status of Volume
glustervol------------------------------------------------------------------------------There
are no active volume tasks
4. client log from node4 when you saw unavailability-
Below are the logs when i reboot server node3, we can see in logs that
"0-glustervol-client-2: disconnected from glustervol-client-2".
Please find the complete logs below from the reboot to until the server
available. I am testing high availability by just rebooting server. In real case
scenario chances are there that server may not available for some hours so i
just dont want to have the long down time.

Hi There,
I have created 3 replica gluster volume with 3 bricks from 3 nodes.
"gluster volume create glustervol replica 3 transport tcp node1:/data
node2:/data node3:/data force"
mounted on client node using below command.
"mount -t glusterfs node4:/glustervol? ? /mnt/"
when any of the node (either node1,node2 or node3) goes down, gluster
mount/volume (/mnt) not accessible at client (node4).
purpose of replicated volume is high availability but not able to achieve it.
Is it a bug or i am missing anything.

Any suggestions will be great help!!!
kindly suggest.
Thanks,Ahemad???________
