Hello all
I have used m/s puppy lots of times and some puppies I save about 6 times and it tells me its time to migrate to a new dvd and the dvd is no where near full Confused I convert most of my pets to sfs files and save them on my hard drive I only save what I have too to the dvd Wink I have had this happen in only puplets not official releases ! Don't no why Confused Currently I am having this issue with raring 3.9.9.2 ! Like I said I have racy, wary, precise puppies on m/s dvd and I do not have this problem !
Also am using the exact same type dvd-r's Any help would be appreciated thank you to all that reply Very Happy

multisession code is very old there may be misunderstandings on correct sizes or code cleanup that forces DVD to look like CD's sizes, CD are very wasteful when it comes to multisession, CD required a large padding between sessions, so around 8 sessions is about max. Also, the toolsets (versions difference) is getting unrealistic too far apart between BK WOOF builds and the spinoffs.
If you want to try moving the burn code from a good working version, over the problematic one in a multisession code session, that works for me when I test. The reading of sessions at boot is the hard one to modify, that requires deep remasters (INIT CODE)

FWIW, I once saved a hundred sessions on a multisession DVD with no troubles at all. I did this probably at least 5 years ago. I don't know which version of Puppy I was using.

PostPosted: Thu 07 Nov 2013, 01:44    Post_subject: What happens when system asks you to Migrate to new DVD?  

Question
Have you had success when asked to migrate with it occurring as you expected?

I cannot find clear understanding of what is occurring, actually, in migration? (for example, is it migrating the contents of the CD/DVD? Is it taking your running system and remastering it? Is is some sort of a combination? Are certain things ignored?

If anyone knows a good write-up of it please post.

Thanks

I have never done this with a any exiisting PUP, but, in the past, with Lighthouse64, I was able to write SFSs to a multisession DVD. This allows the system to pickup the additional SFSs at boot time for use in the running system. I used iGrowISOfs to add SFSs to the multi-session DVD.

With Pups, I believe that the DVD can house, both, your saved-sessions and your SFS and PETs such that all system's needs are solely contained the DVD.

Just an idea which some may find useful.

Thanks guys for replying Wink
Ted Dog that's a good idea ! I will try to compare the files and see if there is a diff in them Wink I assume these would be found in the init script ?
@ Flash: yes I too have burned hundreds when I use to use lucid puppy 5.2.8 no problems Very Happy No problems with the BK builds also have had good luck with slacko 5.3.1 no problems Very Happy As a mater of fact I still use both 5.3.1 @ 5.2.8 m/s dvd's from time to time still work great Wink I have expressed my thoughts before about how I think this is a truly wonderful way to use puppy Linux Wink I am currently working on a project but would love to maybe make this my next : maybe update the scripts for m/s support Wink
@ gcmartin: I know what your saying I have used fatdog m/s as It writes sfs files to the dvd ! works very well Very Happy

I expect the differences are in the BURN scripts, not init scripts but if you are going to diff, they both are available to check, changing init is hard.

Now that I've got two working BluRay's ( Laughing ) and my fingers have become useable again, finger cuts better, I really want to update both 32 and 64 bit Multisession codes and make it, bit more practical. I've left multisession for a while and its clogged my harddrives with copies of everything, never expected I used multisession as an organizational crutch so much. But its a great tool since, once you got it burned its safe, and organized by dates, and stacked newest discs on top.

As I would like a deeper understanding of M/S puppy thanks in advance Wink

burn settings have improved and the base software for optical drives have as well. They need to match for the functionality to work. Only those puppylinux brands that upgraded those base software will work. Fatdog64 those upgrades stuck. Where slacko did support it once but returned to older tools once back to using woof bulids.
Funny thing is half the code ( the ones needed change ) is still in Quirky6 but the calling code is removed.
If you want to play with multisession get a bluray burner and some rewrite discs. They are a third slower to burn with but let you practice.
