It seems to be syncing the files
but very slowly. Also the server load on server01 has risen
to 200+ and the gluster clients are no longer able to access
the mounts. Is there a way to do this that is not as
impactful? Could I manually rsync the bricks before adding
the second node back in?
The recommended way to heal is using the command mentioned. The
gluster self heal daemon takes appropriate file locks before
healing. Since clients are accessing the volume, I don't think
bypassing that and rsyncing the bricks is a good idea.

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.
