I edited this posting because I just realized the solution!
I have a cluster I built and 2 of the systems are running with ZFS on them and one is running EXT4. The EXT4 system has "?" next to "local-lvm" and when a VM was migrated to the EXT4 based node it worked fine, but whence I tried to migrate that VM back to another node it failed. Apparently, the "LOCAL-LVM" having a question mark near it prevented the VM from being able to migrate off the node. The VM's disk is in qcow2 format mounted via SMB share.
I then discovered that the way to get rid of the "?" next to LOCAL-LVM on the EXT4 node was to:
I went into Datacenter -> Storage -> lvm-thin -> nodes -> and then only selected the nodes that actually had LOCAL-LVM on them!!!
Succeeding this modification to my configuration that node no longer showed "local-lvm" at all and then the VM was able to migrate off absent any issues at all!
The reason I was working with EXT4 is that all ever read is that ProxMOX and ZFS will destroy any SSD that is not a commercial grade SSD, so I decided to go to EXT4 (despite liking ZFS a lot) as I do not wish to destroy my SSD.
I'd prefer to configure ZFS in manner it would not work with ProxMox to destroy the SSDs but from what I see that is not really a choice.
