[Gluster-users] delete brick / format / add empty brick

[Alun James]

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 ??
