Bug Description
The ganesha library generates NFS-ganesha exports, one per CephFS share. It sets the unique export ID of an export based on the export ID counter stored in a Ceph RADOS object or in a file backed by a clustered storage
system. The library monotonically increases the export ID counter from 1001 (the first 1000 exports are reserved for non-manila use cases) and assigns the counter value as the export ID of the generated export. It does not re-use export IDs that aren't in use by the current set of exports, e.g. export IDs of exports that have been deleted by the ganesha library. Since the maximum valid export ID of NFS-ganesha server is 65535, it's possible that the export ID counter reaches the limit. The generated exports would no longer have valid export IDs, which would be greater than 65535.
