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.
You cannot delete files from dom_md, this will invalidate the storage domain and you will not be able to use it without restoring these files. The leases file on file storage domain is unused, so creating empty file is enough. The ids file must be created and initialized using sanlock, please you should find instructions how to do it in the archives.
The snapshot was also taken some 4 hours before the attempted import, so I'm surprised the locks haven't expired by themselves...
Leases do not expire if vdsm is connected to storage, and sanlock can access the storage. I'm not sure what do you mean by volume snapshots. To import a storage domain, you should first make that no other setup is using the storage domain. The best way to do it is to detach the storage domain from the other setup. If you are using hosted engine, you must also put the hosted engine agent in global maintenance mode. If your engine is broken, the best way to disconnect from storage is to reboot the hosts. Nir

Any errors in the gluster mount logs for this gluster volume?
How about "gluster vol heal <volname> info" - does it list any entries to heal?
After more investigating, I found out that there is a sanlock daemon that runs with VDSM, independently of the HE, so I'd basically have to bring the volume down & wait for the leases to expire/delete them* before I can import the domain.
*I understand removing /dom_md/leases/ should do the job?
No, the issue is probably dom_md/ids accessed by sanlock, but removing files accessed by sanlock will not help, an open file will remain open until sanlock close the file.
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 you still have these issues, you probably need to remove the previous installation properly before installing again.
Adding Simone to help with uninstalling and reinstalling hosted engine.
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.
