[ovirt-users] Does cluster upgrade wait for heal before proceeding to next host?

I've yet to have cluster upgrade finish updating my three host HCI cluster. The most recent try was today moving from oVirt 4.3.3 to 4.3.5.5. The first host updates normally, but when it moves on to the second host it fails to put it in maintenance and the cluster upgrade stops. I suspect this is due to that fact that after my hosts are updated it takes 10 minutes or more for all volumes to sync/heal. I have 2Tb SSDs. Does the cluster upgrade process take heal time in to account before attempting to place the next host in maintenance to upgrade it? Or is there something else that may be at fault here, or perhaps a reason why the heal process takes 10 minutes after reboot to complete?
