[Gluster-users] Issues with replicated gluster volume

Sorry, It was a typo.
The command i exact command i have used is below.
The volume is mounted on node4.
""mount -t glusterfs node1:/glustervol /mnt/ ""


gluster Volume is created from node1,node2 and node3.?
""gluster volume create glustervol replica 3 transport tcp node1:/data
node2:/data node3:/data force""
I have tried rebooting node3 to test high availability.?
I hope it is clear now.
Please let me know if any questions.
Thanks,Ahemad?

 Hi Ahemad,
A quick question on the mount command that you have used"mount -t glusterfs
node4:/glustervol ? ?/mnt/"
Here you are specifying the hostname as node4 instead of node{1,2,3} which
actually host the volume that you intend to mount. Is this a typo or did you
paste the same command that you used for mounting?
If it is the actual command that you have used, then node4 seems to have some
old volume details which are not cleared properly and it is being used while
mounting. According to the peer info that you provided, only node1, 2 & 3
are part of the list, so node4 is unaware of the volume that you want to mount
and this command is mounting a volume which is only visible to node4.

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???________
