Clonezilla / Discussion / Clonezilla live: Can I run a script after clonezilla finish?

DaiXiTrum - 2009-12-29

Now that I have my clonezilla live running in full automation with PXE boot, I would like to run a script after clonezilla finishes.

I saw a '-o1' parameter during expert mode to run the script in $OCS_POSTRUN_DIR as clone finishes, but I don't know where the OCS_POSTRUN_DIR directory to put my script in?

The variable is in /opt/drbl/conf/drbl-ocs.conf. If you do not modify it, OCS\_POSTRUN\_DIR is:

/opt/drbl/share/ocs/postrun/

I copy my script (named czpostrun1) from my tftp server just before calling the ocs-sr. After clonezilla finishes, I saw a post run message saying that it will run scripts within the …/postrun directory, with 3 lines of asteris (*), but it did not list or run anything.

I checked the /opt/drbl/share/ocs/postrun/ directory, and my czpostrun1 file is in there.

Is /opt/drbl/share/ocs/postrun/czpostrun1 excutable? i.e. is its mode is 755, for example.

Or you can run:

run-parts -test /opt/drbl/share/ocs/postrun/

to see if your command will be excuted or not.

Added the chmod 755 after download the file and it showed up in the list to run.

But now I have a "Exec format error" when clonezilla tries to execute the script. I just have one line in my script to download a file from my tftp server.

Once clonezilla drop out to the command line, I can manually execute my script with bash or sh with no error.

Normally a "Exec format error" means the script was edited on MS windows, and you want to run it on GNU/Linux.

You can use the command "dos2unix" to convert the script file. Then this problem should be gone.

Steven,

I created my file using vi from my other redhat machine, but I ran the dos2unix anyway. Still have the same problem.

After clonezilla drop to a shell, I ran the dos2unix on my script czpostrun1 and ran the 'run-parts /opt/drbl/share/ocs/postrun/' command, and still have the same error.

As a test, I remove my czpostrun1 script and created a file name 'test' with just one line 'echo test1' using vi. Then I ran the run-parts command and got the same 'Exec format error' error message when run-parts tried to execute my test script.

I also tried the dos2unix on the test script and re-run the run-parts, but I still see the same problem.

BTW, I'm using the 20091230-karmic version.

Very weird… You mean you can run the command by ./czpostrun1. But if you run "run-parts ./" it complains "Exec format error"… Weird…

I will try to see if I can reproduce the problem tomorrow.

Yes, that's the problem.

Thank Steven.

I can not reproduce the problem here…
Basically I follow this:
http://clonezilla.org/clonezilla-live/doc/showcontent.php?topic=07_Customized_script_with_PXE

Could you please show us your pxelinux.cfg?

Steven.

This is my default file under pxelinux.cfg (I break down the append line for easy reading)

PROMPT 1

    kernel cz1/vmlinuz
    append initrd=cz1/initrd.img boot=live union=aufs noswap noprompt vga=788

    ocs_live_run="bash /tmp/clonezilla_custom_ocs" ocs_live_keymap=NONE ocs_lang=en_US.UTF-8 nolocales

And this is my clonezilla_custom_ocs file:

#!/bin/bach

# copy the clonezilla_postscript to the /opt/drbl/share/ocs/postrun directory
busybox tftp -g -b 10240 -r czpostrun1 -l /opt/drbl/share/ocs/postrun/czpostrun1 192.168.1.100
chmod 755 /opt/drbl/share/ocs/postrun/czpostrun1
run-parts --test /opt/drbl/share/ocs/postrun
# 2. Restore the image
if mountpoint /home/partimag/ &>/dev/null; then
    #ocs-sr -l en_US.UTF-8 -c -p choose restoredisk "2009-11-12-14-img" "sda"
    #ocs-sr -l en_US.UTF-8 -b -p reboot restoredisk "2009-11-12-14-img" "sda"
     ocs-sr -g auto -v -nogui -b -r -j2 -o1 -p true restoredisk "2009-11-12-14-img" "sda"
else
    [ "$BOOTUP" = "color" ] && $SETCOLOR_FAILURE
    echo "Fail to find the Clonezilla image home /home/partimag!"
    echo "Program terminated!"
    [ "$BOOTUP" = "color" ] && $SETCOLOR_NORMAL
fi

And my czpostrun1

fileName="clonezilla_finished"
echo $fileName
busybox tftp -g -r $fileName -l /tmp/$fileName 192.168.1.100

Steven,

I added the shebang for my czpostrun1 script and it works.

Thanks a lot for your help.

I hope the next ubuntu build will fix that crypto disk problem and I'll be all set.

Thanks for telling us that. Yes, it's better to add shebang in your script.
BTW, I have put a note on http://clonezilla.org/clonezilla-live/doc/fine-print.php?path=./07_Customized_script_with_PXE/00_customized_script_with_PXE.doc#00_customized_script_with_PXE.doc
