NAS200: disks configuration lost!

    Hi,
    I've a NAS200 with a pair of 750GB HDDs and configured as one large disk.

    Couple of days ago I tried to acceed it and I wasn't able to do it so I rebooted the NAS. After that reboot, the NAS looked like factory-new: nothing configured (hostnames, IP, users, disk configuration, etc)

    I moved the disks to my desktop PC and I can see the following partitions

    /dev/sda1 LVM (data)
    /dev/sda2 LVM (config)
    /dev/sda3 swap
    /dev/sda1 LVM (data)
    /dev/sda2 LVM (config)
    /dev/sda3 swap

    Looking at the raw partitions, I was able to recover the LVM configurations and I recreated the filesystems

    $ lvm lvdisplay
    --- Logical volume ---
    LV Name /dev/LVM1/conf
    VG Name LVM1
    LV UUID 0jrXeA-EyiG-NrIv-vxco-am1w-2G01-9yr6eW
    LV Write Access read/write
    LV Status available
    # open 4
    LV Size 464.00 MB
    Current LE 116
    Segments 2
    Allocation inherit
    Read ahead sectors 0
    Block device 253:0

    --- Logical volume ---
    LV Name /dev/LVM/data
    VG Name LVM
    LV UUID E9V8vp-LeH2-7CkF-tip2-bs0H-z7w4-Ebx0dK
    LV Write Access read/write
    LV Status available
    # open 0
    LV Size 1.36 TB
    Current LE 357524
    Segments 2
    Allocation inherit
    Read ahead sectors 0
    Block device 253:1


    The problem that I have right now is that I cant mount the data partition.
    Mounting the conf partition works OK (Is mounted as ext2 and I can access files like smb.comf)
    When I try to mount the data partition (/dev/LVM/data), I get the following error:

    $ mount /dev/LVM/data /tmp/data/
    mount: Mounting /dev/LVM/data on /tmp/data failed: Invalid argument


    Any ideas?

    Thanks!
    Jose
