P2V/V2V errors and storage "failed to stat" errors preventing migration to PVE cluster hosts

I have a Proxmox 9.1.6 - 3 node cluster with shared iscsi LVM flash storage. I have one VM (VM 100) that I can successfully launch/start/migrate/move between hosts so I know the storage and cluster functions are working.

On the hosts I see this in the system log:

Feb 24 16:32:57 pve2 pvedaemon[3290454]: failed to stat '/dev/ssd-lun1-lvm/vm-100-disk-2.qcow2'
Feb 24 16:32:57 pve2 pvedaemon[3290454]: failed to stat '/dev/ssd-lun1-lvm/vm-100-disk-0.qcow2'
Feb 24 16:32:57 pve2 pvedaemon[3290454]: failed to stat '/dev/ssd-lun1-lvm/vm-100-disk-1.qcow2'

And when I try to P2V a machine using Starwind, I get the following error on the target host:

Feb 24 16:36:37 pve1 pvedaemon[3294352]: unable to create VM 201 - lvcreate 'ssd-lun1-lvm/vm-201-disk-0' error: Run `lvcreate --help' for more information.
Feb 24 16:36:37 pve1 pvedaemon[3292326]: <root@pam> end task UPID:pve1:00324490:05CE5999:699E4415:qmcreate:201:root@pam: unable to create VM 201 - lvcreate 'ssd-lun1-lvm/vm-201-disk-0' error: Run `lvcreate --help' for more information.

And the task error on the host:

--size may not be zero.
TASK ERROR: unable to create VM 201 - lvcreate 'ssd-lun1-lvm/vm-201-disk-0' error: Run `lvcreate --help' for more information.

If I try to view the storage details, I don't see any info in the size column:

Keep in mind, I can start/run VM 100 no problem.

I also checked to make sure that the iscsi connections where alive on all the hosts, and they were:

Any ideas?

Thanks!
 
I've gotten around the migration issue by using Veeam to do a Restore to PVE which worked, but still curious about why the "failed to stat" messages and no size reported in the virtual disks...
