Frequently Asked Question

General: Why does my NAS system log report that the “File system is not clean”?
Last Updated 5 months ago

You will see a “File system is not clean” message if a volume containing data was not properly unmounted. This might happen in the following situations:

  • The NAS experienced an abnormal shutdown or forced power off.
  • Some services were not stopped correctly before a NAS shutdown.

If you see this message, you should check the file system of the volume to repair any possible errors.
