Doing a manual restore through command line
First Shred
shred /dev/sda -v -f
Restore Image
ocs-sr -g auto -e1 auto -e2 -batch -r -icds -scr -j2 -p true restoredisk /home/partimag/PAE64_18_04_LTS_EN_250 sda
mount /dev/$source_disk /home/partimag or directly take the image from there
Then try to do the following
ocssr=$(which ocs-sr)
$ocssr -g auto -e1 auto -e2 -batch -r -icds -scr -j2 -p true restoredisk "$IMAGEDIRTOINSTALL" $target_disk
rootuuid=$(blkid |grep ext4 |awk -F'\"' '{print $2}')
echo "rootuuid = $rootuuid"
startpart=$(parted /dev/$target_disk print |grep ext4 |awk '{print $2}')
echo "Partition start at: $startpart" >>/root/labdoo_install.log
echo "UUID ROOT: $rootuuid" >>/root/labdoo_install.log
parted -s /dev/$target_disk rm 1
#Recreate sda1 larger and reset UUID and boot flag
parted -s -a optimal /dev/$target_disk mkpart primary ext4 -- "$startpart" -0
target_disk_1="${target_disk}1"
tune2fs /dev/$target_disk_1 -U "$rootuuid"
parted -s /dev/$target_disk set 1 boot on
#Fsck FS and resize
sleep 2
e2fsck -pf /dev/$target_disk_1
sleep 2
resize2fs /dev/$target_disk_1
#Write install.log
mount /dev/$target_disk_1 /mnt
cp /root/labdoo_install.log /mnt/root/labdoo_install.log
