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.
