Lost Raid volume set

[Nanni]

Hi to all

I have a Big Problem with a Raid 5 system.
The raid 5 system set is composed by 8 HD, 1 Tb each one, no spare disk.
I have had a Black out problem.
After this event, at server restart, the system reports "no Volume is available".
I'm using Areca arc-1220

The Hierarchy is :

Raid Set # 00
Ch01
Missing

Ch05
Ch06
Ch07
Ch08

Ch08 Raid Set # 00 1000.2GB Hitachi HUA721010KLA330

I have a lot of video files on this.
Please, how to recover the Raid set?

You should be able to access the Areca controller and perform a RAID verification for the RAID set 00. I would also check all cables and power connectors to the drives as well and then check from the Areca controller.

Hi and thanks for reply.

When everything were working, I had only 1 raid set 00.
Now I have 2 Raid set 00. (this is wrong)

The missing disks of the first Raid 00 (disk 2- disk 3 - disk4)
are in the second Raid set 00.

How I can bring back Raid set to initial condition?

Did you contact Areca on this issue, it does seem strange for it to have changed.

Hi and thanks for support.
I have received support from Areca and now the Raid set is OK.
Do I have to make some updating for this Nas-R3 version?

Version 5.0.NE46000000.3088
Release date 2008-05-07
