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

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 Status: Connected Number of entries in split-brain: 0 However for example I get different results running (and sorry for the copy/paste storm incoming) [root@ccgl1 ~]# gluster volume heal GLUSTER1 info Brick ccgl1.gl.local:/gluster1/BRICK1/1 /.shard/241a55ed-f0d5-4dbc-a6ce-ab784a0ba6ff.201 /.shard/585c8361-f6a9-48d4-9295-260ec657de1e.49 /.shard/18843fb4-e31c-4fc3-b519-cc6e5e947813.209 /.shard/585c8361-f6a9-48d4-9295-260ec657de1e.48 /.shard/d5a328be-03d0-42f7-a443-248290849e7d.1 /.shard/76b7fe00-a2b1-4b77-b129-c5643e0cffa7.10 /.shard/585c8361-f6a9-48d4-9295-260ec657de1e.47 /.shard/5b708220-7e27-4a27-a2ac-98a6ae7c693d.226 /.shard/f9a7f3c5-4c13-4020-b560-1f4f7b1e3c42.47 /.shard/18843fb4-e31c-4fc3-b519-cc6e5e947813.226 /.shard/18843fb4-e31c-4fc3-b519-cc6e5e947813.192 /.shard -
