    Help! Array troubles!

    in General Support (V5 and Older)

    OK, I need help here-

     

    I've copied over the data from my 2nd data drive to USB drive, data is safe.

     

    Both the 2nd data disk and the parity disk are yellow, and show as DISK_INVALID under unMENU. I've run SMART reports on the data drive it seems fine, only the filesystem is corrupt.

     

    I try and format the drive from the main menu, but nothing happens. If I pop in a fresh disk it says "Invalid expansion" and won't accept it.

     

    I can't format, can't add a disk, can't remove the parity drive, what CAN I do here???

    Little update- I've taken the 2nd data drive and connected it to an Ubuntu PC, and was able to mount it and see the contents, all of which seem to be intact.

     

    I have a brand new drive, not sure of the order of things I should take... The drive is currently unformatted.

     

    Should I:

     

    1- leave the data drive disconnected, connect the new drive and pre-clear it, assign it to the array, then return the data drive and copy it over?

    2- copy the data via dd after pre-clearing the new drive and assigning it to the array?

     

    Thanks for the advice!

    Good morning all,

     

    I'm running the latest 5.0-rc8a, with two 2TB WD Green data drives, 1 2TB WD Green parity drive, and one 500GB Maxtor cache drive.

     

    I noticed yesterday that my second data drive was unassigned, and in unMENU was showing as DISK_INVALID.

     

    Shut the server down, checked cables, rebooted, the disk was there, but had a yellow dot next to it.

     

    Tried rebuilding it, was taking forever (300kb/sec), cancelled it.

     

    At this point, my parity drive showed as unassigned! Rebooted, the drive is assigned but with a blue dot (new drive).

     

    I'm not sure where to go from here- I fear that I now have a lost second data drive with an invalid parity drive that I can't use to rebuild from.

     

    I have the option of starting the array and parity-syncing, but I fear what would happen if I did this.

     

    I'll be heading out today to pick up a new 2TB disk. I'm thinking of dd'ing the second data disk to this new drive as a backup in case the worst happens.

     

    So to recap, I currently have my second data drive with a yellow dot and my parity drive with a blue dot, array is not started.

     

    I welcome your advice.
