Check File System - Planet NAS-5400 User Manual

RAID 1 or RAID 5, the status of the volume will become "degrade."
When a volume becomes "degrade," a "Repair" button will appear on the bottom of the page if
there is available hard disk space on the hard disks that don't compose the degraded volume, and
you can follow the steps below to repair the volume:
1. Click "Repair".
2. Choose the hard disk space to be used in the "Available Space" list.
3. Click the "Add>>" button.
4. Click "Repair" to confirm.
Note:
1. To ensure the data protection mechanism still provides the highest level of safety, you can only
select the hard disk on which the volume is not created while repairing volume space.
2. If there is no available hard disk space on the NAS server when a volume becomes "degrade"
status, please replace the bad hard disk that makes the volume "degrade," and the NAS server
will repair the volume automatically after the new hard disk is inserted
For RAID 5 with Spare Volume
When the spare sub-disk fails
When the spare sub-disk that compose the "RAID 5 with Spare volume fails, the status of the
volume will becomes "Spare sub-disk abnormal," in this case please replace the spare disk for the
NAS server to automatically repair the volume.
When the non-spare sub-disk fails
When any of the non-spare sub-disks that compose the "RAID 5 with Spare volume fails, the
spare sub-disk will take over the failed sub-disk and repair the volume automatically, and after the
repair finishes, the failed sub-disk will becomes the spare sub-disk, and the volume therefore
becomes "Spare sub-disk abnormal," please replace the spare disk in this case
Note: "Spare sub-disk" stands for a hard disk space on a hard disk that composes the "RAID 5
with Spare" volume, while "spare disk" stands for the hard disk with the "spare sub-disk" on it.

Check file system

If the NAS server is improperly shut down or powered off, consistency check and parity check will

And if the hard disk is improperly removed on the parity check stage, the "Volume Setting" page
will show the following message:
The system has detected that the volume needs file system checking. Press Check to begin the
