Thread: Lost Raid volume set

  1. #1

    Default Lost Raid volume set

    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
    Missing
    Missing
    Ch05
    Ch06
    Ch07

    Raid Set # 00

    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.
    All the best,

    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

    Nanni,

    I know I'm digging up an old thread, but can you please give some insight into what caused your strange volume doubling/disk swap and how you fixed it?

    We have a 3ware controller and have experience something similar in conjunction with a freezing Open-E server that is getting almost no traffic.

    Our Controller-1 went from having a 15 disk raid5 unit and single-disk spare unit to appearing to have two 15 disk raids, one with 14 degraded disks one good and one with only one degraded disk and 14 good. the spare unit on Controller-1 is gone.

    Luckily this 40TB array is not in production yet.

    Thanks if you can provide some insight from your experience.
