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?

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.

[Gluster-users] Issues with replicated gluster volume
Hi, Thanks for the clarification. In that case can you attach complete glusterd, bricks and mount logs from all the nodes when this happened. Also paste the output that you are seeing when you try to access or do operations on the mount point.
