I HAVE A SMARTSTORE NS4600 FOR MANY YEARS. I USE 4 HDDs as RAID 5 (Striping with parity) (x4).
One of the HDDs died the other day. ‘RAID Status Critical’
I removed the faulty HDD and installed a new HDD, but the discs would not rebuild themselves. It did not take any action. There is still a red light next to the HDD on the device.
In the RAID Management tab, only the delete tab is active. In the File System Management tab, I only did ‘Check File System’. Again, nothing happened.
I read the user manual and followed the steps. Shouldn't it rebuild itself in HDD replacement? What do I do now? I tried 2 different new HDDs and it was the same.
Is the new HDD file system NTFS, Fat32 or XfaT related to this?
Here's what it says in the user manual:
RAID status: ‘CRITICAL’.
The SmartStor NAS X volume Y
is not functioning correctly.
Check the disc drives. See page 217.
Replace the failed drive. See page
217. The RAID Volume will rebuild
automatically.
8.4 Replacing a Failed Disc Drive
If a disc drive fails, the Disk Status LED is red. See Figure 1. If the disc drive
belongs to a RAID Volume, the Volume goes Critical or Offline. See ‘Checking
RAID Volume Status in WebPASM’ on page 217.
Replace the failed disc drive with a new disc drive of the same or slightly greater
capacity. You do not have to power down the SmartStor.
1. Open the SmartStor's front door.
2. Pull out the drive carrier with the failed drive.
3. Remove the failed disc drive from the drive carrier.
4.4. Install a new disk drive into the carrier.
5. Place the carrier with the new disk drive back into the open slot in the
SmartStor.
If the failed drive belonged to a RAID Volume, the RAID Volume will begin
rebuilding as soon as the new drive is installed.
During the Rebuild, the Disk Status LED show amber. When the Rebuild is
finished, the Disk Status LED turns to normal status color.
7.3 Spare Drive
A spare is a disk drive that has been designated to replace a failed disk drive in a
RAID Volume. In the event of the failure of a disk drive within a RAID 1 or three
drive RAID 5 Volume, the spare drive is activated as a member of the RAID
Volume to replace a disk drive that has failed.
A spare drive cannot replace the failed drive in a RAID 0 Volume because of the
way in which data is written to the disk drives under RAID 0.
A spare drive is not available for a RAID 10 Volume because RAID 10 requires
all four disk drives in the SmartStor enclosure. However, when you replace the
failed disk drive, the SmartStor will automatically rebuild the RAID Volume using
the new disk drive.
You must designate a disk drive as a Spare. By default, and unassigned disk
drive is Free. Use WebPASM to designate the Free disk drive as a Spare. See
Maintaining a spare drive is a good precaution to protect your RAID Volume
integrity in the event of disk drive failure.
