Oops, just realized 3.7.10 had a regression. Then 3.7.11 it is. :)
Wasn't the 3.7.10 regression only a problem on reboots if you used
gluster snapshots? (which proxmox doesn't). I'm currently using 3.7.10,
no issues with restarts so far.
So one of the reasons heal may have taken so long (and also consumed
resources) is because of a bug in self-heal where it would do heal
from both source bricks in 3-way replication. With such a bug, heal
would take twice the amount of time and consume resources both the
times by the same amount.
This issue is fixed at http://review.gluster.org/#/c/14008/ and will
be available in 3.7.12.
Rats, I thought it was in 3.7.11 :( but can't it also be worked round by
disabling "cluster.data-self-heal"? or was that something else.
I'm getting pretty good heal performance with the following settings:
- features.shard-block-size: 64MB
- cluster.self-heal-window-size: 1024
