So I have enabled shading on 3.7.11, moved all VM images off and on and everything seemed fine no issues.

I added a new server(ccgl4) to replace one that nic died. Probed, and moved brick then kicked off heal.
When I did so on the smaller volume that just hosts my hosted engine it completed so fast that engine didnt even hiccup.
When I did same procedure on larger volume all VM's paused. I'm guesing just too many shards healing at once maybe no biggie. I let heal go went to bed for few hours while it healed 600GB of shards.
This morning looks like I may have some split-brain heals going on. All VM's started just fine after I unpausd/re-started them as needed. So far they have been up services seem ok, nothign seems read only etc.
But I have shards that still seem healing after a bit.
split-brain currently shows 0 entries on all 3 nodes (1 example below)
[root@ccgl1 ~]# gluster volume heal GLUSTER1 info split-brain
Brick ccgl1.gl.local:/gluster1/BRICK1/1
Status: Connected
Number of entries in split-brain: 0
Brick ccgl2.gl.local:/gluster1/BRICK1/1
Status: Connected
Number of entries in split-brain: 0
Brick ccgl4.gl.local:/gluster1/BRICK1/1

However for example I get different results running (and sorry for the copy/paste storm incoming)
