    Recovering Partition and data


    Hello Everyone,

    I recently purchased a SATA controller so that I could build a New LVM for my filestorage. My original setup was an 80GB disk for OS and a 1.5TB disk for Storage. The 1.5TB was one large ext4 filesystem.

    The problem came in that I installed the controller connected all of my disks except the OS Disk and booted up. Fedora12 started to boot and failed finding the UUID of the original 1.5TB.

    in my own error I though I already had it set as part of an LVM configuration so I tystem ried to add the PV. Now I have spent my free time the last 3 days trying to get the partition back.

    So far I have tried testdisk and it finds some partitions but I have not had any luck getting a mountable filesystem. I know the data is still there since photorec starts to recover data.

    I also have a 2nd Identical 1.5TB drive if I need it for any purpose, I am hoping someone will have some pointers on how I can get this back the way it was without loosing all the data I had stored.

    Hello and welcome!

    You could also try Foremost to see what it might be able to recover:

    Foremost

    If you can't get back all you need with TestDisk, PhotoRec, and Foremost, I think you might be out of luck unless some commercial service can bring it back for you.

    I'll give that a try before I go to work, I also discovered this:

    parted /dev/sdb
    GNU Parted 1.9.0
    Using /dev/sdb
    Welcome to GNU Parted! Type 'help' to view a list of commands.
    (parted) print
    Model: ATA ST31500541AS (scsi)
    Disk /dev/sdb: 1500GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos

    Number Start End Size Type File system Flags
    1 512B 1500GB 1500GB primary jfs

    JFS? not sure where that came from but I have a feeling that is bad.

    You have not given us nearly enough information.
    When you say "Fedora12 started to boot" what disk was it booting from? Especially if you did not connect your original OS disk.

    Sorry,
    I have my OS disk connected the motherboard in the original configuration and the additional disks are attached to the controller.

    I haven't messed with Foremost yet since I am having troubles getting a file system on my other 1.5TB drive:

    [root@Neon beilber]# mkfs.ext4 /dev/sdc1
    mke2fs 1.41.9 (22-Aug-2009)
    Could not stat /dev/sdc1 --- No such file or directory
    The device apparently does not exist; did you specify it correctly?

    [root@Neon beilber]# fdisk /dev/sdc

    Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes
    255 heads, 63 sectors/track, 182401 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x8bb78879

    Device Boot Start End Blocks Id System
    /dev/sdc1 1 182401 1465136001 83 Linux

    So lets try to get this bad boy on lvm then....

    [root@Neon beilber]# pvcreate /dev/sdc
    Device /dev/sdc not found (or ignored by filtering).

    nope.

    I just reattached all of my additional disks and will get those on the LVM to atleast get a location to restore to.
