Testing Potential Shadow Migration
Configure the source so that the ZFSSA has root access to the share. This
typically involves adding an NFS host-based exception, or setting the
anonymous user mapping (the latter having more significant security
Create a share on the local filesystem with the shadow attribute set to
'nfs://<host>/<snapshotpath>' in the CLI or just
'<host>/<snapshotpath>' in the BUI (with the protocol selected
as 'NFS'). The snapshot should be read-only copy of the source. If no
snapshots are available, a read-write source can be used, but may result in
Validate that file contents and identity mapping is correctly preserved
by traversing the file structure.
If the data source is read-only (as with a snapshot), let the migration
complete and verify that there were no errors in the transfer.
