[Clonezilla-live] Clonezilla / Partclone ext4 problem

[Andreas W. <and...@nt...>]

Hi,

I recently made an image of my HDD using clonezilla live and discovered
a problem with the partclone image of an ext4 partition on that HDD. The
ext4 partition is the root "/" partition of a Fedora 13 installation.

Problem description:

After creating an image (with gzip compression) of the HDD I ran

# cat sda3.ext4-ptcl-img.gz | gzip -d -c | partclone.restore -C -s - -o
sda3.img

to obtain "sda3.img" which I want to loop mount using the command

# mount -t ext4 -o loop,ro sda3.img /media/ext4test/

yielding the following error output from mount

mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

the corresponding dmesg output is

EXT4-fs (loop0): bad geometry: block count 47863659 exceeds size of
device (47712800 blocks)

I searched the web to find out if the problem is more widespread, but I
did not (yet) find anything clonezilla/partclone related.

The partition itself is OK since Fedora 13 boots flawlessly from it and
fsck does not report any errors. However, due to the above error I
cannot run fsck on the file "sda3.img". The error happens with both, the
32-bit and the 64-bit versions of Fedora 13.

Previously I never had problems with clonezilla and ext3 partitions. I
hit this error using clonezilla-live-1.2.5-35-i686.iso and
clonezilla-live-20100721-lucid.iso (the latest stable versions of
clonezilla live).

Additional information is attached.

Did I miss an option in the mount command? Is there something else in
the procedure I am using?

I highly appreciate any help in resolving this problem.

Thank you in advance!

Regards,
Andreas


PS: The "/boot" partition on that HDD also uses ext4 and it can be loop
mounted without any problems from an image using the procedure as
described above.
