MyLiveCd isn't numeric in division and How to code iso into sda2 (Solved)

[Davidsr]

Hi from a old timer and yet still trying to use Linux. Regarding PCLinuxos mylivecd, I have cleared via
BleachBit & Bleachbit-Root and then received this-isn't numeric in division (/) at /usr/sbin/mylivecd line
244--so to me it appears I am trying to make a cd/dvd that the sda1 hasn't enough size to handle-but to me there is enough space?. So my question to you-If I am correct about this, could you please provide me the coding to sent the mylivecd .iso
to my other HDD sda2, where I have 97% of this HDD not used.
df shows the following and umount -a doesn't clear the tmpfs, states all 3 are needed/in use;

Filesystem     Size   Used    Avail   Used%   Mounted
/dev/sda1      111g    5.8g    94g     6%      /
/dev/sda2      111g    2.4g    109g    3%      /home
tmpfs          505m    112      505m   1%      /dev/shm

Thank you.

Hi Davidsr

What is the actual command you are using - can you please post it in full

Might be able to "remove" folders that aren't required in the LiveCD.

[Davidsr]

menotu, thank you for your reply;  in addition I tried again using the --lzma and mylivecd failed again, also I have read many many postings and saw what one stated that 2.9gb was max for use of mylivecd? yet in another the guy did make mylivecd work on a 5gb
/, what I don't understand after researching my File System Properties is a difference in size of df as 5.8gb and using File System Properties that shows a 9.7gb size. I remember that after Bleachroot it showed my Root size was 700Mb yet I have / installed in the first HDD with Avail of 99g and /Home in the 2nd HDD. Again Thanks, heres what I did;

Davidsr:

Your kernel is too old. Install one of the 2.6.38.8 kernels, then try again.

[and then..]

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             111G  5.8G   99G   6% /
/dev/sdb1             111G  2.4G 108G   3% /home

Davidsr,
5.8 + 2.4
Looks to me like you are trying to remaster greater than 8 GB

Davidsr,

One can remaster up to ~12 GB if one intends to burn the .iso to a DVD disk. The heavy compression used should reduce the image created to ~4 GB.

[Just17]

 

this-isn't numeric in division (/) at /usr/sbin/mylivecd line 244

this error appears if the livecd.sqfs file for the ISO is >~4GB ...... ~4GB is the limit of any single file within an ISO.

As o-p pointed out, use a newer kernel and better compression to reduce the size of the livecd.sqfs file and all should complete.

[AS]

/dev/sdb1             111G  2.4G  108G   3% /home

Usually 5.8+2.4 = 8.2 Gb when compressed result in approx. 1/3 of the average size, however things could be different if i.e. the home folder content is already compressed, like could be in case of jpeg photos: in such case the result will be 1/3 of the '/' filesystem (approx 2.0 Gb) + nearly the original size of /home (2.4 Gb), thus exceeding the maximum 4 Gb allowed from mylivecd.

Compression ratio depends from source files types.

Davidsr,
you could try to temporarily exclude the /home filesystem, and retry to build your iso only from your '/' filesystem,
using the option --nodir, and eventually backup separately the /home folder.

mylivecd --nodir ^/home livecdaugust.iso

AS

[Davidsr]

  dud my brain!!! Thank you all. Old-Polack I read this morning about the kernel from the help file of mylivecd, I just though that the install cd had a newer kernel, then I read about the default kernel that goes into a cd unless the person adds the newer kernal. My machine has been on oh 4 hours now doing a mylivecd --nodir^/home livecd august.iso

Again my thanks to all. oh I hope I typed right with a space than --???

Again, thanks to all for your replies. Newest update, BTY, I also am trying mylivecd cause of several view points-1. can I get it to work on my machine, 2. I'm 65 years old and have the time to try, 3. I am a previously programmer in ZBasic and lately I'm bored so back to work with the OS I have found to enjoy.
I have updated the kernel to 2.6.38.8-pclos3 and have attempted to make a .iso and its keeps failing, my / root is on sda1 and /Home is on a different HDD sdb1, these are the only two partitions I set up. Now I agree with the size limition of about 4gb, however I have gone thru a lot of directories and still (except for one) haven't figure out why I am unable to make mylivecd work-? is it a lot of empty space that or on my HDD???.
I have a question about the directory /var/cache, which holds the .rpm packages. Why store them? I haven't asked to download these rpm's and should they be deleted/removed? If so How? I see #rpm -e ,but I am concern that it will also remove the applications that I wish to keep (or is this just in some other OS's that remove the applications, and PCLOS doesn't?), but I have 2Gb's of rpm packages in this directory.
Also, BleachBit doesn't delete files that are locked, causes Error 13, but the archieves hold the rpm's files and other files that I wonder should be allowed to be deleted?
Or am I the one who is Lost In Space???
Again, Thanks.

There is no reason to store them after installation, unless you want them for use with another installation and don't want to download them again. In Synaptic, Settings --> Preferences you can choose to save them or delete them, as shown below.



If, after making that selection, you install any application, large or small, the cache will be automatically cleared of all previously saved packages.

Rpm -e will uninstall the application, and not remove the saved packages.

[Davidsr]

 
please review the following, can you tell me where my iso is stored? The *.iso doesn't show when doing a search.
Thanks

  Thank You All!!! While unable to locate my successful .iso (see above), I attemped another run by using mylivecd --xz --tmp=/home/davidsr/ --md5sum --ufs unionfs /livecd/whatever.iso  and found this took a very long time on my 1MB ram machine, so I closed out the Terminal and rebooted (twice) then went back into BleackBit & BleachBit-Root (will post a message about BleachBit later) and started over with a Reboot twice again, so I have had 6 reboots trying to learn mylivecd. So I decided to search again for my original .iso and since I used the code of-- nodir the Home--, I looked thru the Root directories and found my .iso-I have no idea why the OS Search still didn't show this .iso . The file was 1.4Gb so a DVD was made, took the DVD to my other computer (newer) and turned on the machine and up pops the PCLinuxOS reading the DVD, since there's no HOME the OS stated many things and then I grew worried about this wording--Problem with configuration server (/usr/lib/gconf-sanity-check-2 exited with status 256) with only a Closed Button, yet the arrow still was in a circle, so I click on the Closed Button and Saw the OS without its Home-mylivecd and the DVD worked!!! But I had everything located in HOME, so even with a router connection the Browser and email application didn't work, thats not a problem, I tickled the DVD works. In my opinion its the machine ram/memory not recognizing/seeing the .iso file. Tomorrow-HOME will be added-I hope? There both still under 10Gb!

Davidsr,
You posted the same question about your ISO location in 2 threads. Don't do that. Double posting is unnecessary and against forum policy.
I answered your question in the other thread.
