Well that didn't go so well. I deleted both dom_md/ids & dom_md/leases in
the cloned volume, and I still can't import the storage domain.
The snapshot was also taken some 4 hours before the attempted import, so
I'm surprised the locks haven't expired by themselves...

I'm testing this with volume snapshots at the moment, so there are no
processes accessing the new volume.
Did you try to reboot the host before installing it again? If you did and

The Hosted-Engine database had been corrupted and the restore wasn't
running correctly, so I installed a new engine on a new server - no
restores or old data. The aim is to import the old storage domain into the
new Engine & then import the VMs into the new storage domain.
My only problem with this is that there appear to be some file based
leases somewhere that, unless I manage to locate & delete them, force me to
wait for the leases to timeout before I can import the old storage domain.
To minimise downtime, I'm trying to avoid having to wait for the leases to
timeout.

Doug
