I had setup two 500gb disk in RAID0 on my server, but recently suffered a hard disk failure (saw a S.M.A.R.T error on the HDD at boot). My host has put 2 new disk in RAID-0 again (re-installed the OS) and re-attached the old drives on the same machine, so that I can recover the data.

My old drives are:

/dev/sdb and /dev/sdc

How can I mount these two disks back in RAID0, so that we can recover the data from our old drive? Or is this not possible any more? Have I lost all my data?

This is my /etc/fstab and df -h: http://i.imgur.com/iVjpDNN.png

This is my fdisk -l: http://pastebin.com/raw.php?i=68puYEXD

I read somewhere that you can do this with this command: mdadm -A --scan however, it does not yield any result for me -> No arrays found in config file or automatically

Any help/tips/advice regarding this is much appreciated.

  • 1. You do not have a raid 0 in use right now. 2. Please show us "mdadm -E /dev/sdc1" and "mdadm -E /dev/sdb5" and "cat /proc/mdstat". – tim Apr 29 '13 at 14:58

RAID0 and data recovery do not go well together. By using RAID0, you doubled your chances of catastrophic failure. At this point, you have two options:

  1. Restore from backup.
  2. Send the disks off to a professional data recovery company.

By mucking around with the disks any more yourself, you're just decreasing the chances of ever being able to get data off of them.

  • Wish I could give you more than +1. Never, ever, try to mess with this sort of thing yourself, if you value the data at all. – Tonny Apr 29 '13 at 15:04
