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.
