Hi folks,

I had a 2 node (1 brick each) replica, some network meltdown issues seemed to cause problems with second node (server02). glusterfsd process reaching 200-300% and errors relating to split brain possibilities and self heal errors.

Original volume info:

Volume Name: myvol
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: server01:/brick1
Brick2: server02:/brick1

I removed the second brick (that was showing server problems).

gluster volume remove-brick myvol replica 1 server02:/brick1

Now the volume status is:

Volume Name: tsfsvol0
Type: Distribute
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: server01:/brick1

All is fine and the data on working server is sound.

The xfs partition for server02:/brick1 has been formatted and therefore the data gone. All other gluster config data has remained untouched. Can I re-add the second server to the volume with an empty brick and the data will auto replicate over from the working server?

gluster volume add-brick myvol replica 2 server2:/brick1 ??


Yes this should work fine. You will need to run a  `gluster volume heal myvol full` to manually trigger the replication.
