Recovering Partition and data

[beilber]

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

Number Start End Size Type File system Flags

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.
