mylivecd running on portable usb drive --SOLVED

[jordanin]

I have been having an interesting time trying to get mylivecd to run off of a version I installed onto my portable usb drive. I made a ~60 GB partition and wiped the rest of the drive. I then used full monty November version to install to it. I thought I could delete some of the larger programs that I don't need and then fit it on a 4 GB stick.
So I removed about 2GB of the ~13 GB and then ran bleachbit and bleachbit root. Next I tried umount -a but it gives device is busy, and I don't see anything else mounted other than the 1 partition that has the full monty install. Then I tried mylivecd LivePClinuxOS.iso and about 10% through the compression it turns off my computer. I have tried about 5 times and every time with the same result. I don't see an error message before it happens, although I have to admit I don't sit and stare at the konsole. Any ideas will be greatly appreciated. I am trying to convert people by handing out 4 GB flash drives and I would like them to see how much linux has to offer.

.....I tried umount -a but it gives device is busy....

That's normal. You can't unmount your running system.

This should help --

I used the df command and I got the following results
9.7 GB used and 46 GB available
It was 8.9 GB used before I attempted to mylivecd and now even after bleachbit, bleachbit root, and cleaning /tmp I still get 9.7 GB used.
It only makes it ~20% through the compression when the computer power turns off. I read all the way through the suggest thread and didn't see anything that applied to my problem. I am not excluding anything, and I started with the full monty iso then removing a couple of gigs of programs. I assume full monty was built using this script, but that might not be the case. I see no error message it just shuts down. Any ideas?
Thanks,
Jordan

Run bleachbit and bleachbit root again. Unless you need them, you can delete the logs at /root/.synaptic/log (must be done as root). Yes, mylivecd is the tool used in remastering.

I think your problem may be related to something else. mylivecd does not turn off the computer. If it fails, it returns an error message. Using the livecd, run memtest. This will test your RAM, the most likely fail point, I think.

Thanks for the suggestion Neal. I ran memtest yesterday and after 2 passes it was still showing no errors. I left it running while I was away and when I came home the computer was off. Any ideas?

It appears to me that something in your hardware is failing. Exactly what, I don't know.
Perhaps a new post in the hardware section would elicit some helpful responses from people knowledgeable in hardware issues.

Because creating a new ISO is likely to stress the PC, it may be that it is overheating during the process and shutting down for protection.

Is this a laptop?

[jordanin]

It is a desktop, and it would appear that I have a temperature issue. I watched the CPU temperatures while trying to run mylivecd and after a few minutes of continual rise they were pegged. I then tried the portable on my old laptop and it successfully created and iso. So while my temperature issue isn't solved yet, I now totally agree it was not the script. Thanks for all your help.

Glad we could help and you have found the problem

Odds on it's just dust in the airways.  My method of cleaning is to jam all the fans with matchsticks and then use an air hose to blow it all out! (If you use such a vicious method, it's necessary to jam the fans or you may wreck them on overspeed!)  Alternatively a compressed air can may do. 
Or you can do it the hard way and take things apart......
