System is setup using OMV  and Gh with 3 Gh drives.
Gh1 300Gig, Gh1 200Gig and Gh1 200Gig,
A Small 10 Gig filesystem with a single share called Data is used for the smb shares.

Soft links (ln -s) point to the Gh landing zones on Gh1 (Movies, Music, Photos,...)

ln -s /media/uuid(Gh)/Movies  /media/uuid(Data share)/Movies

ln -s /media/uuid(Gh)/Music  /media/uuid(Data share)/Music

ln -s /media/uuid(Gh)/Photos /media/uuid(Data share)/Photos

Test1) Remove Gh2 and see what happens...

[Seagate Barracuda ST2000DM001] NFS/NFS_3-000002.vmdk

can't be moved because it is inclued in snapshots (crap)

moved it to another Vitural Device Node (SCSI (0:9))

Everything worked fine... OMV moved it to /dev/sde1

Veeam Backup whole system

Restore to new location

remove snapshots of restored VM
