[Gluster-users] 3.8.3 Shards Healing Glacier Slow

Tue Aug 30 15:02:30 UTC 2016

updated test server to 3.8.3

Brick2: 192.168.71.11:/gluster2/brick2/1

kill -15 brickpid
rm -Rf /gluster2/brick3
mkdir -p /gluster2/brick3/1
mkdir mkdir /rhev/data-center/mnt/glusterSD/192.168.71.10

/rhev/data-center/mnt/glusterSD/192.168.71.10\:_glustershard/fake2
gluster v start glustershard force

at this point brick process starts and all visible files including new dir
are made on brick
handful of shards are in heal statistics still but no .shard directory
created and no increase in shard count

gluster v heal glustershard

At this point still no increase in count or dir made no additional activity
in logs for healing generated.  waited few minutes tailing logs to check if
anything kicked in.

gluster v heal glustershard full

gluster shards added to list and heal commences.  logs show full sweep
starting on all 3 nodes.  though this time it only shows as finishing on
one which looks to be the one that had brick deleted.

my hope is that later tonight a full heal will work on production.  Is it
possible self-heal daemon can get stale or stop listening but still show as
active?  Would stopping and starting self-heal daemon from gluster cli
before doing these heals be helpful?
