Chapter 8 Storage Table 24 Storage > Volume (continued) LABEL DESCRIPTION Disk(s) Click or roll your mouse over a link in this column to display the following details about the hard drive located in the corresponding hard drive bay. Capacity Actions Type: Whether it is an internal or external (USB) hard drive. Model Name: This is the hard disk number that identifies the disk. File System: The file system that an external volume is using Capacity: The total storage space on the disk. This field shows total disk size, the percentage of the volume being used and the percentage that is available. This field displays icons allowing you to edit, scan, repair, expand, migrate, or delete a volume. You can also locate or eject an external volume. Note: If you delete a volume, all data in the volume disk(s) is erased. You see a warning screen before you delete a volume. Figure 88 Delete a Volume Warning Screen 8.2.3 Volume Status You (the administrator) can see the status of a volume in the Status or Storage screens. The NSA has the following classifications for the status of a volume: • Healthy if all disks in the volume are OK and the file system is functioning properly. • OK means the USB connected device is functioning properly. • Resync when you create a RAID volume. • Recovering appears when repairing a RAID 1 volume. (A RAID1 volume was once degraded, but you have installed a new disk and the NSA is restoring the RAID1 volume to a healthy state.) • Degraded when a volume is currently down, but can be fixed. Data access may be slower from a degraded volume, so it's recommended that you replace the faulty disk and repair the volume as soon as you can. • Inactive when a disk is missing from a RAID 0 volume or a two-disk JBOD volume. The volume is unusable. If you removed one of the disks you should be able to re-install it and use the volume again (as long as you did not change anything on the disk). If a disk has failed, you need to replace it and re-create the whole volume. All data will be lost. See page 344 for how to install or replace a hard drive. • Down when a volume is down and can not be fixed. A down RAID volume cannot be used until you repair or replace the faulty disk(s) in the volume. Degraded means one of the disks in the RAID volume is not available but the volume can still be 164 Media Server User's Guide

Volume Status
You (the administrator) can see the status of a volume in the
Status
or
Storage
screens.
The NSA has the following classifications for the status of a volume:
Healthy
if all disks in the volume are OK and the file system is functioning properly.
OK
means the USB connected device is functioning properly.
Resync
when you create a RAID volume.
Recovering
appears when repairing a RAID 1 volume. (A RAID1 volume was once degraded, but
you have installed a new disk and the NSA is restoring the RAID1 volume
to a healthy state.)
Degraded
when a volume is currently down, but can be fixed. Data access may be slower from a
degraded volume, so it’s recommended that you replace the faulty disk and repair the volume as
soon as you can.
Inactive
when a disk is missing from a RAID 0 volume or a two-disk JBOD volume. The volume
is unusable. If you removed one of the disks you should be able to re-install it and use the
volume again (as long as you did not change anything on the disk). If a disk has failed, you need
to replace it and re-create the whole volume. All data will be lost. See page
344
for how to install
or replace a hard drive.
Down
when a volume is down and can not be fixed.
A down RAID volume cannot be used until you repair or replace the faulty disk(s) in the volume.
Degraded means one of the disks in the RAID volume is not available but the volume can still be
