Failed to save partition: split_error.L6wzCO

[Kirkx]

1) I have installed Clonezilla on a dedicated logical partition on the hard disk and I boot to it using the following command in Grub4Dos (a bootloader related to legacy Grub):

---

title Clonezilla Live on HDD
root (hd0,41)
kernel /live-hd/vmlinuz boot=live live-config noswap nolocales edd=on nomodeset ocs_live_run="ocs-live-general" ocs_live_extra_param="" keyboard-layouts="" ocs_live_batch="no" locales="" vga=791 ip=frommedia nosplash live-media-path=/live-hd bootfrom=/dev/sda42 toram=filesystem.squashfs
initrd /live-hd/initrd.img

---

The Clonezilla boots without errors, just like any other distro, but an attempt to create an image of Xubuntu fails at root partition image (home partition image is ok).

Source Partitions:
/dev/sda23 Ext4 (15 GB) Xubuntu root
/dev/sda24 Ext4 (3 GB) Xubuntu home

Target Partition:
/dev/sda36 Xfs (30 GB) empty

The command Generated by Clonezilla after going through all the menus is as follows:

/usr/sbin/ocs-sr -q2 -c -j2 -z1 -i 2000 -p true saveparts 2014-08-21-07-img sda23 sda24

Here is the last section of the log file "saving-error-201408210736" showing "split_error.L6wzCO":

2) I also can't figure out how the command generated by Clonezilla is supposed to work. It can apparently be used straight from Clonezilla's command line when you decide to create another partition image later on (the date/time needs to be modified manually, I guess):

/usr/sbin/ocs-sr -q2 -c -j2 -z1 -i 2000 -p true saveparts 2014-08-21-07-img sda23 sda24

But how would Clonezilla know what is the target partition (/dev/sda36 in this example)? And where is /usr/sbin/ directory located, I can't find it anywhere on the dedicated Clonezilla partition:

And it's nowhere to be seen at the target partition either:

I would write:
kernel /live-hd/vmlinuz initrd=/live-hd/initrd.img boot=live ..

(not newline initrd /live-hd/initrd.img )

Fuchs, according to Grub4Dos guide initrd.img should be on the separate line. I've been booting to Linux Lite and Xubuntu that way for a few months now w/o any problems:

http://diddy.boot-land.net/grub4dos/files/boot.htm#linux

Ref-op-1) I have changed the "-i" parameter from 2000 to 1000000 to disable image file splitting. You will find this trick in one of the help menus shown when you run Clonezilla and select "custom" option at one point. This actually solved the problem for a while and I was able to create the image of that 15 GB root Xubuntu partition, but after a few more test runs the error came back. It is actually a bitmap free count error:

extfsclone.c: bitmap free count err, free:2580671

Ref-op-2) I have figured that out. First you need to mount the target partition to /home/partimag and then run the command:

/usr/sbin/ocs-sr -q2 -c -j2 -z1 -i 1000000 -p true saveparts yyyy-mm-dd-hh-img sda23 sda24

You can apparently aslo include all those parameters somewhere in the boot command or create a script. It's all explained here:

Clonezilla uses syslinux 6.03 as operating system with the own commands and messages. These ones are often similarly to the other ones (Grub4Dos).
Normally it's better to start clonezilla separately, from a USB stick.

I have not experimented with Grub4dos. So I can not say anything about that. An interesting version.
You can make a look for 'Grub4Dos ? ' in Clonezilla live.

## For some reason my post above (from Sep-05) got stuck "awaiting moderation", so I'm re-posting below. Moderators: please cancel/delete that stuck post. ##

Thanks, Fuchs. I have resolved the error issue reported before:

extfsclone.c: bitmap free count err, free:2580671

This error has actually been well documented. It is file system integrity issue and the solution is to include the following parameter in the command:

-fsck-src-part
or:
-fsck-src-part-y

http://clonezilla.org/clonezilla-live/doc/01_Save_disk_image/images/ocs-10-check-source-fs.png

So, for the record, the proper command set is as follows:

sudo su -
mount /dev/sda36 /home/partimag
/usr/sbin/ocs-sr -q2 -c -j2 -z1 -i 1000000 -fsck-src-part-y -p true saveparts yyyy-mm-dd-hh-img sda23 sda24

[Fuchs]

That's very fine. Thank you for this information.
