Ok.

I am not sure deleting the file or re-peer probe would be the right way to go.

Gluster-users can help you here.

Hello!

I haven't change the IP, nor reinstall nodes. All nodes are updated via yum. All I can think of was that after having some issue with gluster,from WebGUI I deleted VM, deactivate and detach storage domains ( I have 2) , than, manually, from one of the nodes , remove bricks, then detach peers, probe them, add bricks again, bring the volume up, and readd storage domains from the webGUI.

What are the steps which led this situation?

Did you re-install one of the nodes after forming the cluster or reboot which could have changed the ip?

Hello!

I have an ovirt setup, 3.4.1, up-to date, with gluster package 3.5.0-3.fc19 on all 3 nodes. Glusterfs setup is replicated on 3 bricks. On 2 nodes 'gluster peeer status' raise 2 peer connected with it's UUID. On third node 'gluster peer status' raise 3 peers, out of which, two reffer to same node/IP but different UUID.

in every node you can find the peers in /var/lib/glusterd/peers/

you can get the uuid of the current node using the command "gluster system:: uuid get"

From this you can find which file is wrong in the above location.

[Adding gluster-users@xxxxxxxxx]

What I have tried:

- stopped gluster volumes, put 3rd node in maintenace, reboor -> no effect;

- stopped  volumes, removed bricks belonging to 3rd node, readded it, start volumes but still no effect.

Any ideas, hints?

TIA
