Description

RecoverLease should be return false when the file is open or be writing in multiple destinations.

Liks this:

Mount point has multiple destination(ns0 and ns1).

And the file is in ns0 but it is be writing, ns1 doesn't has this file.

In this case recoverLease should return false instead of throw FileNotFoundException.
