Clonezilla / Bugs / #254 Unable to find target partition "sda4".

Steven Shiau - 2016-07-12

For the files you provide, it looks like /dev/sda4 does not exist on your hard drive:
8 0 976762584 sda
8 1 512000 sda1
8 2 512000 sda2
8 3 32768000 sda3
8 5 32768000 sda5
8 6 32768000 sda6
8 7 865357824 sda7

This is weird... From the results of sfdisk, apparently it's created.
After you see the errors, can you verify that by running:
cat /proc/partitions
then post the results.
Thanks.

Steven

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

after clonezila writes the image back sda4 is missing, based on the image i attached, does it even saves it ?

redone the steps using:
drbl-2.20.33-drbl1 clonezilla-3.22.8-drbl1 partclone-0.2.89-drbl1 drbl-chntpw-20110511-1drbl mkpxeinitrd-net-2.3.11-drbl1 ipxe-20140910-drbl1 freedos-1.0-19drbl util-linux-2.27.1-6ubuntu3.1 gdisk-1.0.1-1build1

installed pristine source HDD, and rebooted

Check if the partition sda4 really exists, otherwise maybe the kernel is too old.

The case is really weird to me. I have no idea why it happens. What's the OS which you are restoring?
If there is no classified data, and if it's not very huge, maybe share the image to me so that I can try to reproduce the issue here.

Mircea Dan - 2016-07-28

in the sda4.zip i included all the files except the data files, see picture with the files i included and the files i left out, will it be posible to use some standard junk data files (i assume those shoudl play no role in the partition table)

the OS i try to restore is centos 7

Still I can not find any clues abut why it happens there. No idea what to do next. I wish I can access that machine and check more.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

so i cannot provide the original image but i did as much as posible to provide something similar, i zeroed the disk

dd if=/dev/zero of=/dev/sda -seek=0

than created same 7 partitions and the logic volumes

# aproximate code it may miss a command or two here and there that refreshes the partition tables or a reboot here and there, but the bulk is in here to create same partition structure.

export DISK1="/dev/sda"
echo -e "n\np\n1\n2048\n1026047\nt\n6\n\nn\np\n2\n1026048\n2050047\nt\n2\n83\n\nn\np\n3\n2050048\n67586047\nt\n3\n83\n\nn\ne\n67586048\n1953525167\n\nn\n67588096\n133124095\nt\n5\n83\n\nn\n133126144\n198662143\nt\n6\n83\n\nn\n198664192\n1953523711\nt\n7\n8e\n\np\nw\n" | fdisk ${DISK1}
echo -e "a\n2\nw\n" | fdisk ${DISK1}

mkdosfs -F 16 ${DISK1}1
mkfs.ext4 ${DISK1}2
mkfs.ext4 -F ${DISK1}3 
mkfs.ext4 -F ${DISK1}5
mkfs.ext4 -F ${DISK1}6

reboot

pvcreate ${DISK1}7
vgcreate vg_02 ${DISK1}7
lvcreate -n lv_swap -L 4G vg_02
lvcreate -n lv_home -l 100%FREE vg_02
lvchange -a y /dev/vg_02/lv_swap
lvchange -a y /dev/vg_02/lv_home

lvdisplay
kpartx -av ${DISK1}
vgscan
lvscan
mkswap /dev/vg_02/lv_swap
mkfs.ext4 -F /dev/vg_02/lv_home

reboot

now i looked to see if i have same disk structure

lsblk -o TYPE,NAME,KNAME,UUID,MOUNTPOINT,SIZE

and i got same structure exctley like in the above posts

now i started clonezilla and this is the command that was generated

/usr/sbin/ocs-sr -q2 -c -j2 -z1p -i 4096 -scs -p choose savedisk 7part2 sda

and you can find attached the full image (a bunch of partitions with no data in them)

now i deleted all the partitions and cleaned /dev/sda and rebooted (this is how i deleted teh partitions: fdisk /dev/sda d1d2d3d4w)

and now i tried to restore this image and the problem reproduced
Unable to find target partition "sda4".

clonezilla-log.zip

Mircea Dan - 2016-08-10

had a breakthrough and i belive is all related to the cleanup.
i deleted everything, partitions, lvms, zeroed the disk, went all out of wiping everything. (clearley overboard)
rebooted
restored the image and it restored properley
rebooted
executed same exact command to restore the image and surprise unable to find targeted partition "sda4" error.

somehow i belive clonezilla does not wipes etc etc properley the hdd before writing it.

i think this comamnds are doing the job of cleaning up
export DISK1="/dev/sda"
sudo vgremove vg_02
sudo pvremove ${DISK1}7
sudo dd if=/dev/zero of=${DISK1}7 bs=1M count=1
sudo kpartx -dv ${DISK1}
echo -e "d\n1\nd\n2\nd\n3\nd\n4\nw\n" | sudo fdisk ${DISK1}

i also noticed some of this commands are not blocking or how to say, if you just paste them sometimes the ydon't work, but if you do them 1 by one the OS has enough time to propagate the changes so maybe a timeing issue

so at this time i have 2 speculations: cleanup issue (wipeing lvm and old partitions from targed disk) or timing issue.

  Hi,
  when i create a live usb, i believe this fix is not present.although i use the latest clonezilla/drbl version, did this fix also made it to the iso that is being downloaded and modified when the live usb image is created ?i still see the issue even today when i create a live usb stick from an image.
  Thanks,Mircea Dan
