Stolen space
The volume reports stolen space. This means that storage capacity which should be available for use in this volume
is instead used elsewhere. Depending on the volume type, examples may be:
- Redundancy and/or parity for data recovery after a disk failure.
- Space used by other volumes in the same pool if the pool is overcommitted.
- Space used for snapshots.
- Snapshots limiting the maximum amount of data that can be written to the volume.
