mylivecd and 11.5GB of data

[gezza]

Hi to all,
I have been 'trying' to remaster my system but with no success.
The system is as follows:-----
mylivecd  --xz --tmp=/mnt/data/temp --nodir=^/mnt,^/media,^/home/gerald/tmp /mnt/data/my32-2012.02-21052012.iso
ls: cannot access /mnt/data/my32-2012.02-21052012.iso: No such file or directory
Argument "" isn't numeric in division (/) at /usr/sbin/mylivecd line 248.

Created '/mnt/data/my32-2012.02-21052012.iso' (0,000 bytes) in 00:33:44

Now 11.5Gb is a max as a lot of / data is not included as is my tmp folder, so it may be only 11GB to remaster.
I have run Bleachbit as a user as root and that removed 500MB of data so it should work, but does not.
Any help will be gratefully received.

Argument "" isn't numeric in division (/) at /usr/sbin/mylivecd line 248. is telling you that there's too much data to fit on a 4.3GB DVD. According to AS, the maximum disk size you can get to a single layer DVD is somewhere between 10 and 12GB of data on disk. You might try excluding more directories.

[root@ws1 ~]# df  -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              25G  8.1G   15G  36% /
/dev/sda2              31G  3.4G   28G  11% /home
/dev/sdb2             1.8T  509G  1.2T  30% /mnt/data

Given the available space on the /home and / partitions, I see no reason not to unmount the data partition, unless there is data in there that you want to include. Use the /home partition for the working files and the ISO, or even split them between the two partitions.

Second thing I would do is to use a '--workdir' so that if the result is larger than can be included in an ISO, the files would still be present for examination afterwards. In fact they could be used on a LiveUSB  which is not limited in size like the ISO.

If all works out correctly the '--workdir' can be deleted and the ISO copied to the Data partition after remounting it.
