Locate image and go there, you will find files like: "sda1.ntfs-img.aa" and "sda1.ntfs-img.ab" ...
Find what compression has been used, gzip, bzip or lzop?
file *.ntfs-img.aa
Note: the image you are about to extract will be sized to the original partition-size, unused space included. This can take quite some time and disk space.
Windows NTFS partition
Npte: I didn't test this yet (201309).
Guide:
Extract
Install partclone:
add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse" apt-get update apt-get install partclone
Install ntfsclone:
sudo apt-get install ntfsprogs
Extract partition image (sdb1) from CloneZilla:
cat sdb1.ntfs-ptcl-img.gz.* | gzip -d -c | partclone.restore --restore_row_file -F -O -C -s - -o sdb1.img
Define device md0 and mount it:
mdconfig -a -t vnode -f sdb1.img md0 mkdir /media/mnt mount -t ntfs /dev/md0 /mnt
Resize
Check for errors:
dmesg | tail
Check for the minimum size:
ntfsresize -m /dev/md0
Apply the resize (here 36Mb)
After the resize, the imagefile stays at its original size, it's not automatically truncated. We use ntfsclone to extract the relevant data in the next step.
Note that this can take considerable time:
ntfsresize --size 36M /dev/md0
Clone to get the minimum size. The --force is necessary because the resize action flags the volume for a chkdsk check.
ntfsclone --force -o sdb1_shrunk.img /dev/md0 mdconfig -d -u /dev/md0
Restore
Restore to partition, in this example /dev/sda1.
THIS WILL OVERWRITE THE TARGET PARTITION!! ALL DATA ON THAT PARTITION WILL BE LOST!!
Note: after this only the earlier 'minimum size' of the partition is used
partclone.restore -d -s sdb1_shrunk.img -o /dev/sda1
Resize to fit partition:
ntfsresize -x /dev/sda1
Linux ext4 partition
Extract
Install partclone:
add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse" apt-get update apt-get install partclone
Lets say compression is gzip (as it probably is), then we need to extract the image using gzip:
Options:
- -C ignore size errors
- -F force
- -O overwrite
- -s <> source, specify - to use standard input (pipe)
- -o <outputfile>
cat sda5.ext4-ptcl-img.gz.* | gzip -d -c | partclone.restore --restore_row_file -F -O -C -s - -o sda5.img
Mount/unmount with:
mkdir /media/ubuntutje mount -o loop -t ext4 sda5.img /media/sda5img umount /media/sda5img
Resize
You can do this instead of using CloneZilla if you have 'geometry' errors or other problems.
Check for (mount) errors:
dmesg | tail
Fix errors (if any)
fsck.ext4 -f sda5.img e2fsck -f sda5.img
Resizing the filesystem on sda5.img to minimum size. Note: this can take a lot of time
resize2fs -M sda5.img
Restore
Restore to partition, in this example /dev/sda3.
THIS WILL OVERWRITE THE TARGET PARTITION!! ALL DATA ON THAT PARTITION (/dev/sda3) WILL BE LOST!!
Note: after this only the earlier 'minimum size' of the partition is used
partclone.restore -d -s sda5.img -o /dev/sda3
Resize partition to fit the whole available space:
e2fsck -f /dev/sda3 resize2fs /dev/sda3
