Heal process seems to be stuck at the following:

gluster v heal datastore4 info
Brick vnb.proxmox.softlog:/tank/vmdata/datastore4
Status: Connected
Number of entries: 0

Brick vng.proxmox.softlog:/tank/vmdata/datastore4
<gfid:be318638-e8a0-4c6d-977d-7a937aa84806> - Possibly undergoing heal

Status: Connected
Number of entries: 1

Brick vna.proxmox.softlog:/tank/vmdata/datastore4
<gfid:be318638-e8a0-4c6d-977d-7a937aa84806> - Possibly undergoing heal

Status: Connected
Number of entries: 1

I'm on my home now, will be offline for a couple of hours. But for now
my cluster is offline.

hi Lindsay,
      Something doesn't sound right. If you had enabled locking-scheme to granular, 'Possibly undergoing heal' message should never come. I think the problem seems to be something to do with this option in your case. VMs freezing suggest that some processes are still doing old style locking which can block the writes. Can you try resetting the locking-scheme option?
