Hi,
My workstation is running CentOS 7 on two disks (sda and sdb) in a
software RAID 1 setup.
It looks like I accidentally nuked it. I wanted to write an installation
ISO file to a USB disk, and instead of typing dd if=install.iso
of=/dev/sdc I typed /dev/sdb. As soon as I hit <Enter>, the screen froze.
I tried a hard reset, but of course, the boot process would stop short
very early in the process.
Now, I have backups of the important stuff of course, so no real
catastrophe. But it would be nice if I could get back the data from my
disk directly.
I booted a rescue disk (Slax 9.6.4) and I can see my disks as well as
raid arrays /dev/md125, /dev/md126 and /dev/md127. Oh, my partitioning
scheme is manual and quite simple. Everything is RAID 1, I have a /boot
array on /dev/sda1 + /dev/sdb1, swap on /dev/sda2 + /dev/sdb2 and / on
/dev/sda3 + /dev/sdb3.
I tried to mount /dev/sda3 directly from the rescue disk:
# mount /dev/sda3 /mnt
But I only get this:
mount: unknown filesystem type 'linux_raid_member'
I'd be very grateful for suggestions.
Cheers,
Niki
