This is rather concerning. How does one setup high availability for VM's, to auto restart when a host node fails, of HA breaks the whole cluster?

As matter of interest, did you partition your drives? And what were your findings?

please explain, what is a linked clone?

Do I need to use one WAL per OSD if I use spinning disks?

Did you ever get to the bottom of this?

How exactly does one passthrough a SSD from the host node to a VM?

What would happen if the WAL disk fails?

So how does one get 2Gb speed across 2 NIC's?

ok

Which RAID cards do you use? Some Dell RAID cards don't offer HBA mode

Is it possible to share a CEPH WAL between all the OSD's, instead of having to partition the WAL? If I have 12 drives, I have to create 12 equal partition on the WAL, and assign each partition to an OSD. Is there a better way to assign the WAL?

Is it possible to move a VM between CEPH and ZFS in a mixed environment like this?
