Hi all,

I encoutered the same problem I think, using Partimage 0.6.6 from SystemRescueCD 0.4.3.

I did save an NTFS partition of 78GB (/dev/hda1) to a USB disk mounted thru ntfs-3g (ntfs-3g /dev/sdb1 /mnt/windows), using GZIP compression and automatic image split.

Saving works fine and leaves a 'quarkt-sda1.000' file of about 67GB.

Upon restore, I get an 'Invalid compression level for /mnt/windows/quarkt-sda1.000' error within the GUI.

I tried to rename the file to 'quarkt-sda1.000.gz', and lauched parted again, but got the same message.

I could not gunzip the image, as I do not have enough room on the disk. Peeking at the archive contents, I could see 1) the compression ratio was wrong 2) the uncompressed name was the same as the archive name (which suggests one should rename the archive created by PartImage in every case):

~# gzip -l /mnt/windows/quarkt-sda1.000

compressed uncompressed ratio uncompressed_name
68639053700 1266326748 -5320.3% quarkt-sda1.000

You'll find hereafter the contents of the '/var/log/partimage-debug.log' file.

As a workaround, I'll try the 'gunzip -c <imagefile> | partimage restore <partition> stdin' tip as suggested in the forum [1].

Hope this helps, Olivier

The following workaround, as suggested on the forum, allowed me to restore the partition:

~# gunzip -c quarkt-sda1.000.gz | partimage restore /dev/sdc1 stdin

I also reran gzip with the --verbose switch, which gives some more details. Here is its output:

method crc date time compressed uncompressed ratio uncompressed_name
defla 793e397d Apr 1 07:04 68639053700 1266326748 -5320.3% quarkt-sda1.000

I also tried to save a FAT32 partition, with GZIP compression and automatic split. It gave me a 'quarkt-sda2.000' file of about 3.3GB, which I also stored on ntfs-3g mounted NTFS partition on an external USB disk.

When I tried to restore that file, I ran into the same issue, I received an 'invalid compression level' error, followed by a segfault. You'll find partimage's debug log hereafter.

So it seems the problem isn't directly related to the partition type.

Peeking into the GZIP archive with gzip -l -v:

~# gzip -l -v quarkt-sda2.000

method crc date time compressed uncompressed ratio uncompressed_name
defla 0187f4c9 Apr 2 12:03 3633808305 4048330556 10.2% quarkt-sda2.000

In that case I had enough room, so I renamed the archive to 'quarkt-sda2.000.gz', extracted it with 'gunzip -d quarkt-sda2.000.gz' and then could restore the extracted 'quarkt-sda2.000' with partimage (partimage restore /dev/sdc2 quarkt-sda2.000).

Hope this provides some kind of useful information.

Kind regards,
Olivier

Gold is created past drops and looting. Inflation. The only thing which in turn causes inflation is Farming mobs for items and gold.

Hunger is the main reason people often lose the battle in a diet. the extra you eat, The more your stomach stretches and therefore you hold more and more food leading you to gain more weight. Also the bigger you get the more your metabolism slows down leading you to gain even more weight. This pill helps curb your appetite and speeds up your metabolism which in turn burns more fat and carbs causing you to lose the weight. With a proper diet and prescription drugs the payout is weight loss podedsja.
