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.
