Re: mdadm raid5 dropped 2 disks

Hi Wol,
the raid is save now. I didnt work on the disks itself only with images.

dd if=/dev/sd[abc]1 of=/mnt/image[123].dd bs=1

losetup /dev/loop1 /mnt/image1.dd
losetup /dev/loop2 /mnt/image2.dd

mdadm --create /dev/md0 --raid-devices=3 --level=5 --assume-clean 
--size=976631296 --raid-devices=3 missing /dev/loop2 /dev/loop1

fsck without any errors. Data is back!

What I maybe did wrong in the first run?
1) I wrote the first backup of the disks to partitions, that were a 
little bigger than the original one. These were fresh drives with no 
data writen so far.
2) I did the create with the right order (missing loo2 loop1)  from 
mdadm -E "Device Role"

glad it worked. Will save lsdrv and hope never to use it. Create new 
backupplan!

cheers
