Clonezilla / Discussion / Clonezilla live: Clonezilla and nbd using imagemount generate an issue

Biagio De Maio - 2017-11-15

I have got a problem trying to use imagemount command when I use the nbd device.
I found this example to extract the partition image file and mount it on a nbd device :

sudo cat sdb1.ext4-ptcl-img.gz.* | gzip -d -c | partclone.extfs -r -o sdb1.img --restore_raw_file
sudo modprobe nbd
sudo imagemount -d /dev/nbd0 -f /home/partimag/my-sdb1.img
sudo mount -t ext4 /dev/nbd0 /mnt

but I got anyway the same error :

sdb1.img: cannot verify: Invalid argument

I used Clonezilla Live on USB to backup my partitions and this is the ocs-sr command :

/usr/sbin/ocs-sr -q2 -c -j2 -zip -i 4096 -sfsck -senc -p choose saveparts 2017-11-15-01-img.boot sdb1

and I tried on all partition's image saved getting same results.
I tried to use the SystemRescuecd's partclone.dd v.0.2.89 and got a positive result ... why this ?
Using loop device all is working, instead, and using mount command it work.
I updated my ubuntu 17.10 with partclone v.0.3.11 and partclone-utils v.0.4.11 and checked the
Clonezilla tools about the release adn found that use the same partclone v-0.3.11 but parclone-utils
is v.0.4.1-dbrl1
May be I am doing something wrong or it's not possible to use nbd device ?!?
Please help me as I don't know who can explain me the problem and give a solution !
Another question I would ask here, it's possible to manage a backup's image making persistent modifies (like mounting deleting or adding files into and then saving it) to use that image in a future
recovery ? otherwise there is a way to make something like that ?
with regards

Which versions of partclone-utils and Clonezilla live did you use? I'd like to reproduce this issue here.
Thanks.

thanks for your reply dear Steven, I was loosing any hope to get an answer.
I use the clonezilla-live-20171101-artful-amd64.iso and last version of partclone-utils v.0.4.11, the partclone tool is v.0.3.11.
Further I would ask You how to get a version persistent of your livecd to get stored ocs scripts to reuse everytime I need make a backup, as /tmp folder will be cleared at exiting.
I will wait an you reply chance, thanks.

"I use the clonezilla-live-20171101-artful-amd64.iso and last version of partclone-utils v.0.4.11, the partclone tool is v.0.3.11." -> Because Partclone 0.3.x uses new image format, so you have to ask the developers of partclone-utils to improve that to fit the new image format.
For the time being, I suggest you use other mthods mentioned here:

Just in case Google brings someone here, I'd like to mention that I have forked partclone-utils here https://github.com/prekageo/partclone-utils and added support for the image format version 0002.

Great. Thank you very much.
BTW, will you give it a version number when you think it's ready?
If so, it's easier for us to package it and include it in Clonezilla live.
Appreciate.

Hi Steven,

The original author has accepted my pull request. I've made a second one (https://sourceforge.net/p/partclone-utils/git/merge-requests/2/) to bump the version. I hope that he will merge it as well.

Thanks,
George

  George,
  I tried to package your version (git clone https://github.com/prekageo/partclone-utils.git) on Debian 10. However, I got an errror:
  partclone_imageinfo.c:145:42: warning: format ‘%lld’ expects argument of type ‘long long int’, but argument 4 has type ‘int64_t’ {aka ‘long int’} [-Wformat=]
  fprintf(stderr, "%s: cannot malloc %lld bytes\n", argv[i],
  ~~~^
  %ld
  partclone_blocksize(pctx));
  ~~~~~~~~~~~~~~~~~~~~~~~~~
  make[3]: *** [Makefile:523: partclone_imageinfo.o] Error 1
  
  Where did I miss? Have you successfully compiled it on Debian 10 or Sid?
  Thank you very much.
  
  Steven

    Hi Steven,
    
    Thanks for catching that. Apparently, I tested only imagemount. I have updated the repositories (both on GitHub and here) with the fix for imageinfo. I have also updated the merge request to the original repository.
    
    Let me know if it works now.
    
    Thanks,
    George

Yes, great. Thank you very much. Once it's released as new version number, we will package it and use it in Clonezilla live.

George,
Yes, I have successfully packed it as partclone-utils 0.4.2-pre1 and include it in testing Clonezilla live 2.6.3-5:
https://clonezilla.org/downloads.php
If you have time, please give it a try and let us know the results.
Thanks you very much.

Hi Steven,
A user of partclone-utils found some bugs (https://github.com/prekageo/partclone-utils/issues/1). I have fixed them and updated the repositories (Github and here).
Thanks,
George
