<br>
I am running replica 3 gluster with 3 bricks. One of my servers failed - all disks are showing errors and raid is in fault state.<br>
<br>
Type: Replicate<br>
Volume ID: 41d5c283-3a74-4af8-a55d-924447bfa59a<br>
Status: Started<br>
Number of Bricks: 1 x 3 = 3<br>
Transport-type: tcp<br>
Bricks:<br>
Brick1: node1.san:/tank/gluster/gv0imagestore/brick1<br>
Brick2: node2.san:/tank/gluster/gv0imagestore/brick1 <— this brick is down<br>
Brick3: node3.san:/tank/gluster/gv0imagestore/brick1<br>
<br>
So one of my bricks is totally failed (node2). It went down and all data are lost (failed raid on node2). Now I am running only two bricks on 2 servers out from 3.<br>
This is really critical problem for us, we can lost all data. I want to add new disks to node2, create new raid array on them and try to replace failed brick on this node. <br>
<br>
What is the procedure of replacing Brick2 on node2, can someone advice? I can’t find anything relevant in documentation.<br>
<br>
Thanks in advance,<br>
Martin<br>
