Appsync 3.8 Force Expire Mounted copies

Hey all,

We have had a situation where we've had a problem between VMWare and AppSync, and when unmounting, it has errored for some time, keeping copies on AppSync marked as Mounted, but removed them from the host, allowing a new copy to be mounted in its place.  Our sysadmin has then been manually removing the copies.

We believe we have that underlying problem fixed - but AppSync is out of sync with the reality of snapshots on our XtremIO, and obviously, what is currently mounted.

Is there any way I can Unmount and Expire the copies that no longer exist? I cannot re-mount or similar, as they have been removed from storage.
