No takers on this one?
Hi John,
If you either replace a brick of a replica or increase the replica count
by adding another brick, you will need to perform `gluster volume heal
<volname> full` to sync the data into the new/replaced brick.
If you are running glusterfs 3.6 or newer. there is a bug (underfix ) in
'heal <volname> full` due to which heal won't be triggered in some
scenarios, in which case you can trigger lookups from the mount (find
/mount-poin |xargs stat). Lookups would also trigger heals.
You can then remove the replaced brick if there are no more pending heals.
HTH,
Ravi

Until last weekend we had a simple 1x2 replicated volume, consisting
of a single brick on each peer. After a drive failure screwed the
brick on one peer we decided to create a new peer and swap the
bricks. Running "gluster volume replace-brick gluster-rhev
dead_peer:/gluster_brick_1 new_peer:/gluster_brick_1 commit force".
After trying for some time and not wishing to rely on a single peer
we added kari as an additional replica with "gluster volume add-brick
gluster-rhev replica 3 new_peer:/gluster_brick_1 force".
Can we now *safely* remove the dead brick and revert back to replica 2?
regards,
John
