<div style="font-size: 10pt;">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?</div>

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. <br>

fine. You will need to run a `gluster volume heal
myvol full` to manually trigger the replication.</font></font><br>
