-This deactivates a given volume. This is useful to process a volume stopping the volume server. Possible use cases are compaction, index recreation or moving the volume to another server. As soon as a volume is unmounted it won't be accessed by the volume any more and can be safely changed or moved away.

-```bash
-curl "http://localhost:8080/admin/volume/unmount?volume=volumeId"

-The counterpart is to mount a volume. This adds a volume file to a volume server without the need to restart the volume server. A use case is to mount a previously unmounted volume again or to add a volume, that has been moved to another server to the new server.
