3 node HCI 2+1 data/arbiter
added 3 compute-only nodes via host install without HE support which
add no storage to the gluster (install still adds them as peers).
With 2 compute-only nodes inactive/down I updated the third compute
node (no contributing bricks) and saw all VMs pausing and glusterd on
the HCI nodes "lost quorum on brick engine/vmstore/data" when it
rebooted to activate the new kernel.
Had to launch additional compute-only node to let glusterd on HCI nodes
recover quorum.
Seems glusterd computes quorum based on total peers (6) not on
redundancy (2+1).
With the gluster volumes down, running VMs remain paused according th
virsh, HE and UI aren't there, hosted-engine --vm-status reports "not
retrieved from storage"

Hi Thomas,
Quite strange.
Get to one of the gluster tsp nodes and provide some data:
gluster volume list
gluster pool list
for i in $(gluster volume list); do gluster volume status $i;echo; gluster volume status
$i; echo;echo;echo; done
Best Regards,
Strahil Nikolov
