RAID
When you have configured RAID-1 configuration and you experience a single disk failure, you will
be able to see status message as seen below. Here you can see that Raid error is stated.
When you have replaced the faulty hard drive with a new one the NAS server will rebuild the
RAID-1 configuration by mirroring everything on the healthy hard drive to the new hard drive and
therby restoring the RAID-1. This progress starts up as soon as you have placed the new hard drive
in to the NAS server, and turned on the server. Note that you should not insert new hard drive in to
the NAS server while the server is turned on.
To see the progress of the rebuild, you must logon to the NAS server again and go in to the USB
Devices and click on the Refresh button as seen below.
Note that the rebuild process can take long time to finish, as it depends on the size of the hard
drive. It is very important not to turn off the NAS server during the rebuild process. Example the
rebuild of an 80GB hard drive will take approximately 45 minutes.
Using the NAS during the rebuild process will extend the rebuild time.
Please note:
to identify which disk has an error, please turn off the NAS server and disconnect one
hard drive, now start the NAS server again. If you can access your data, you have removed the
defective disk. If not, the defective disk is the one still in the NAS server.
