How to create an ISO image ?

[erbou]

Hello,

From the whisker menu, I launch the MX snapshot application.
My system occupies 7 Gb on my hard disk which has 200 Gb left.
In the application window, I answer /media/Backup_Linux/MX_snapshot/snapshot as the output directory and a subdirectory named mx-snapshot-NKIXq6G7 is created right away.
Unfortunately, 1 hour and 30 minutes later, the process is still running and although a child subdirectory has been added to mx-snapshot-NKIXq6G7, no .iso file seems to have been created :

Code: Select all

root@ttx:/media/Backup_Linux/MX_snapshot/snapshot# ls -al

-rw-r--r-- 1 root root 110240 nov.  19 15:47 package_list

So, where can I find out the .iso file ?

That's a work directory, it should be deleted once the process is over, not sure why it got stuck, it shouldn't take that long. Try to start mx-snapshot from CLI.with "sudo -E mx-snapshot" and post here the last messages you see before it gets stuck, it could give me a clue of what is going on.

Here is what I've done

Code: Select all

tt@ttx:/media/Backup_Linux/MX_snapshot/snapshot
$ sudo ls -al mx-snapshot-tUjCVj9u
total 12
drwx------ 3 root root 4096 nov.  20 09:42 .
drwxr-xr-x 3 root root 4096 nov.  20 09:42 ..
drwxr-xr-x 6 root root 4096 nov.  20 09:42 iso-template
tt@ttx:/media/Backup_Linux/MX_snapshot/snapshot
$ sudo cd mx-snapshot-tUjCVj9u
sudo: cd: command not found
tt@ttx:/media/Backup_Linux/MX_snapshot/snapshot
$ sudo -E mx-snapshot

As soon as I hit the <Enter> key, it launches MX snapshot application again and nothing else.

and the previously launched one is still running 1 hour and 25 minutes later

Is this MX 15 like in your sig?

[erbou]

No, I used MX-16.1

How is the /media/Backup_Linux/ disk location connected to your system and what type of storage medium is it? I have the impression that it is through USB, which can be a serious bottleneck, esp if a Windows type file system is used.

When I create a fresh ISO, use the defaults and the ISO is created in /home/shapshot/ on my internal hard disk. I then copy it to a removeable drive if I want to archive it, checksum the files and remove the original if I really want to reclaim drive space if the checksums match. Can I suggest you do the same to test the process on your machine and report back.

/media/Backup_Linux is an ext4 partition recorded on a hard disk drive installed in my desktop PC and connected by a SATA cable to the motherboard.
I use the default /home/snapshot setting but it didn't not help.
Something seems weird about that process : at some step, I am asked "Do you wish to continue ? (Y/n)" : but whatever key I might hit, it is not displayed and I don't know whether it is even got by the application. Instead the blue slippery ribbon keeps on scrolling from left to right even 2 hours and a half later !
If I cancel the process, the temporary directory it has created from start gets erased.
