HDD defect (sda) - primary

Change primary hard-drive (Resellerserver)

Note: there is not possible to repare a HDD with fsck

==> boot into Rescue-system

mkdir /mnt
mkdir /mnt2
mount /dev/sda2 /mnt
mount /dev/sdb2 /mnt2
rsync -avz --progress --exclude 'spool/mqueue' --delete /mnt/* /mnt2/.
 
mkdir /mnt3
mkdir /mnt4
mount /dev/sda3 /mnt3
mount /dev/sdb3 /mnt4
rsync -avz --progress --delete /mnt3/* /mnt4/.
 
mkdir /mnt7
mkdir /mnt8
mount /dev/sda5 /mnt7
mount /dev/sdb5 /mnt8
rsync -avz --progress --delete /mnt7/* /mnt8/.
 
mkdir /mnt9
mkdir /mnt10
mount /dev/sda6 /mnt9
mount /dev/sdb6 /mnt10
rsync -avz --progress --delete /mnt9/* /mnt10/.

Hetzner lets to change a harddrive and now boot into rescue-system again:

sfdisk --dump /dev/sdb > diskparts.txt
sfdisk /dev/sda < diskparts.txt
 
mkswap /dev/sda1
mkfs.ext3 /dev/sda2
mkfs.ext3 /dev/sda3
mkfs.ext3 /dev/sda5
mkfs.ext3 /dev/sda6
mkfs.ext3 /dev/sdb7
 
mkdir /mnt11
mkdir /mnt12
mount /dev/sda7 /mnt11
mount /dev/sdb7 /mnt12
rsync -avz --progress --delete /mnt11/* /mnt12/.
