Hi! Some kind of strange behavior occurred while using our 4-nodes S2D cluster. After some connectivity problems (nic teaming bug or, maybe, something else) cluster shutted down, storage pool became "Unhealthy", Operational status "Read only", Reason - "Majority Disks unhealthy" with all Physical Disks "OK" and "Healthy" status. Storage Enclosures and Storage Subsystem are Healthy as well. December commulative update was installed, servers rebooted many times, Cluster and pool were shutted down and brought up again - all with no luck. Logs:

Any ideas? Is there a way to make Storage Pool Healthy again? Thanks!
