WHAT WE ARE TALKING ABOUT

Lacie CloudBox is a NAS server for home or small office.

More information: http://www.lacie.com/uk/products/product.htm?id=10597

GOAL

Problem:

If the ethernet port becomes unavailable we get a big problem.

Goal:

Recover the data storaged in the hard disk.

I’m using an Ubuntu Linux 12.10 Desktop for that pourpose.

PLUG HARD DRIVE

We have to extract the hard disk from the box and plug it into our PC. Piece of cake!

MAIN ISSUE

We can’t mount the data partition because of the file system.

With parted or Gparted frontend we can see our data in partiton number 8

USING PARTED

#apt-get install parted

#parted -l

Model: ATA ST1000DM003-1CH1 (scsi)Disk /dev/sda: 1000GBSector size (logical/physical): 512B/4096BPartition Table: gpt

Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB grub_core bios_grub 2 2097kB 203MB 201MB ext2 boot_rescue 3 203MB 204MB 1049kB ext2 nv_data 4 204MB 1815MB 1611MB ext2 root_1 raid 5 1815MB 3426MB 1611MB ext2 root_2 raid 6 3426MB 4499MB 1074MB ext3 var raid 7 4499MB 4768MB 268MB linux-swap(v1) swap raid

8 4768MB 1000GB 995GB user_dataraid

USING GPARTED

SO LET’S MOUNT!

If we try to mount that partition as usual we get this:

#mount /dev/sda8 /mnt/disk/mount: unknown filesystem type 'linux_raid_member'

More information about RAID & LVM2:

http://en.wikipedia.org/wiki/Logical_Volume_Manager_%28Linux%29

THE SOLUTION - 1 STEP

Install this packages:

For create & manage raid#apt-get install mdadm

For manage LVM2#apt-get install lvm2

THE SOLUTION - 2 STEP

Mount /dev/sda8 in /dev/md0

#mdadm --assemble --run /dev/md0 /dev/sda8

If md0 is being used choose another one

LVMDISKCAN SHOWS /DEV/MD0#lvmdiskscan

LVDISPLAY SHOWS LV NAME

THE SOLUTION - FINAL STEP

Create a folder for mounting the partition with our files

#mkdir /mnt/disk

Mounting /dev/vg/lv

#mount /dev/vg/lv /mnt/disk/

HERE WE HAVE OUR DATA

Data is in “shares” folder

#ls -l /mnt/disk/
