i saw djohnston answer in another topic

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.

What should I do now ?
how can i fix it

df output :

Code: [Select]

[root@localhost ~]# df
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda5              98G  8.6G   85G  10% /

any idea

[johnmart]

Hi raed. as djohnston's quote said;
" You might try excluding more directories."
You can use a command-line option to exclude diectories that contain large files; movies, music, iso's etc.
Here's an example taken from the mylivecd help file.

mylivecd --nodir ^/usr/src/RPM,^/root/tmp livecd.iso

you can add other options after the --nodir string.
hth

[raed]

be patient with me

simple i need that iso i can burn it to dvd when i install it give me pclinuxos with my settings Especially sound settings

"mylivecd --nodir ^/usr/src/RPM,^/root/tmp livecd.iso"

is it save my customization ?
this command will save "livecd.iso" in "/root/tmp" is that right ?

you say i can add other options after the --nodir string like what for example .

[raed]

/usr/sbin/mylivecd --splash=silent livecd.iso

what does it mean "--splash=silent" ?

[djohnston]

"mylivecd --nodir ^/usr/src/RPM,^/root/tmp livecd.iso"

is it save my customization ?

If your customizations are in your home folder, then yes. You have not excluded your home folder from the remaster.

this command will save "livecd.iso" in "/root/tmp" is that right ?

The iso will be saved in whatever directory you are in when you run the script. If you are in the /root directory when you run mylivecd, the iso will be saved in the /root directory. If you want it saved in /root/tmp, then run mylivecd like this:

mylivecd --nodir ^/usr/src/RPM,^/root/tmp /root/tmp/livecd.iso

you say i can add other options after the --nodir string like what for example .

Too many to list here. For a list of all options, enter:

mylivecd --help

[raed]

mylivecd --nodir ^/usr/src/RPM,^/root/tmp /root/tmp/livecd.iso

I understand now , I'm going to try it

[raed]

[raed]

is this important step ?

Code: [Select]

umount: /: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

!!

i skipped that

Yes. Post result of

is everything OK ? i can't see iso file in home or root !!

[smudger]

raed:

Code: [Select]

mylivecd --nodir ^/usr/scr/RPM,^/root/tmp pclinuxos.iso

I notice from your syntax that you have used ^/usr/scr/RPM please change the scr to src
otherwise this directory will be missed from your .iso

i can't see iso file in home or root !!

Have you tried (as root):
locate pclinuxos.iso or whereis pclinuxos.iso

this should give you the full path to where your pclinuxos.iso file has been placed

You could append a path to the pclinuxos.iso file in your original syntax, for better usability.

is everything OK ? i can't see iso file in home or root !!

Look in the root user's home folder, /root, not in the global root folder, / (which Dolphin calls "Root").

(You have to be root to access /root.)

[raed]

Do I repeat the process with change the scr to src

Code: [Select]

[root@localhost ~]# locate pclinuxos.iso
/root/pclinuxos.iso

  that means there is iso file in /root ? but in dolphin i can't see it so how can i copy it or burn it ?

[raed]

is everything OK ? i can't see iso file in home or root !!

Look in the root user's home folder, /root, not in the global root folder, / (which Dolphin calls "Root").

(You have to be root to access /root.)

i understand now 
i copy it now 
cp /root/pclinuxos.iso /home/raed

now i see the iso file

is there anything else or just burn it ? how can i use it ?
install it from dvd like install pclinuxos

Just click its icon (or double-click it if that's how you've set up your system). As you seem to be running KDE, that should by default open K3b ready to burn it. After that the easiest way of installing it would be from the live DVD that K3b creates.
