Removing a Missing SSD Cache


You should only delete a missing SSD cache if it is not possible to restore the cache, for example, because of disk failure.


Removing a missing SSD write-only or read-write cache will delete all unflushed write data.

  1. Go to Storage & Snapshots > Storage > Cache Acceleration.
  2. Select Manage > Remove.

    A confirmation message appears.

  3. Enter the admin password.
  4. Click OK.
  5. Restart the NAS.
  6. Run a file system check on all volumes that used the SSD cache.

    For the details, see Volume File System Check.
