The rsync Download Post is Gone April 18, 2007

Posted by Carthik in ubuntu.
trackback

The rsync download/update cdimage article I wrote is no more. Both Jonathan Riddell and Matt Zimmerman left a comment on the post to say that the excessive load caused by rsyncing users would kill the rsync server. So while this might have worked for one or two people, it won’t work if everyone tries it. I believed the best thing to do was to make the article “private” so as not to cause undue stress on the servers – I love servers and won’t have them thinking bad of me. I like humans too, and am sorry for posting a “solution” that was flawed.

The right thing to do would be to download the image through bittorrent the day Feisty is released. We have to be patient. 🙂

What in we bittorrent a beta iso now and then rsync after. Is this possible and couldn’t this potentially lead to less strain on the servers on d-day. In the past the severs have been extremely slow on a new release. Thoughts?

2. Sencer - April 18, 2007

It’s odd that Ubuntu is not picking up a solution that’s been working for Debian. Namely jigdo:

http://www.debian.org/CD/jigdo-cd/

Sure, it may not be the best end-user-friendly way to distribute it to everyone. But for the many hightly-interested people that follow development and every beta/rc release.

3. Sencer - April 18, 2007

Oh my, the embarassment! Scratch my last comment. There have been jigdo-downloads available for the Ubuntu releases, they are just not talked about much. They are available in the download-directories.

So everybody who was interested in the rsync idea, should give jigdo a chance, it’s pretty similar in terms of transfer and “assembly”, but it doesn’t require the constant checking and rechecking of pieces on the server for comparisons which pieces have changed as with rsync (because the difference information is distributed in the .jigdo/.template files).

How’s waiting for a week and then going to an offshore mirror ?

At least for people who’ve got bittorrent blocked by their ISPs, it’s a sane choice.

Sencer, talk about embarrassment – I am much to embarrassed right now, too. Jigdo is cool, yes.

Elias, the rsync after is the problem. Please don’t do it.

When I wrote the original I thought about how the (rsyncing) mirrors will have competition from normal users who are also rsyncing, but I chose to ignore it – I should not have.

7. Colin Watson - April 18, 2007

Elias: There have been sufficient changes from beta to release that rsyncing that difference will probably not save much bandwidth, certainly not enough to compensate for the significant computational cost of rsync.

8. Bill K. - April 18, 2007

Boooo

j/k, I forgive you. 😉

9. harrytuttle - April 18, 2007

what about zsync?
it offloads the computational cost to the client.

7.04 release images are already on their way to mirrors. Our Latvian mirror has been syncing already since afternoon, hope that it will be here in the morning!

11. limak - April 18, 2007

Yes, try jigdo.
I have already downloaded latest feisty-alternate iso. I used previous beta of feisty for that purpose so i didn’t have to download all iso. And tomorrow I’m going to download final feisty (alternate and desktop) iso using jigdo and newly downloaded version.
I’m curious about how many MB will I have to download tomorrow. 🙂

hi

can we download this newer version straight to edgy or do we still have to download a ISO? I have edgy running now, and i cant tell you all the mistakes i have made since this am, i lost access somehow to my software properties are in system , i click it and it begins to open then its simply gone, and i cant find any of the beryl files that were in the synaptic package manager, this is so much harder than i had thought it would be. i refuse to give in tho, so if you have some ideas of how i can either redo this system now to fix what i caused or if you can tell me if i can just download to desktop the new version tomorrow, that would be awesome
thanks
🙂

Why not just install one of the daily builds that is available now and do another upgrade when it gets released in a few days. http://cdimages.ubuntu.com/daily/current/

What are the odds that you are going to re-download another 650MB of upgrades once the final release comes out on the 19th of April. NO chance since we are in Release mode.

Its misconception that because a software comes out on release day is going have that “new car smell / bug free” that we all enjoy. Trust me, Feisty on release day is great but the upgrades that come after are even better.

You should be able to upgrade to Feisty from update-manager, or you can change your /etc/apt/sources.list from edgy->feisty, and do sudo apt-get update, sudo apt-get dist-upgrade

15. The Linux site - April 19, 2007

With so many people downloading Feisty tomorrow, will be plenty of seeders, and should be fast to get the Feisty copy.

Off course we can always just upgrade our Edgy to Feisty

[…] Sembla que la solució que proposava ahir de descarregar Ubuntu Feisty a través de rsync per accelerar la descàrrega ha fet que els servidors es saturessin i els administradors han desactivat l’accés. […]

I intend to support the torrents as much as possible. I have fairly good bandwidth and will run a few different versions for about a month after release. I would guess that a lot of people will share that attitude and I think the torrents will, as a result, be ridiculously quick.

I however will be trying out the edgy-feisty upgrade path before falling back to a total reinstall if needed.

Hi, I’d like to download the new Ubuntu release but the Ubuntu site is currently down 😦
Too visitors, I suppose…

19. markus - April 19, 2007

As I wrote yesterday, it would be really easy (for example at next release for 7.10) for everyone to download a daily image via bittorrent a few days beforehand, then seed, remove the torrent from your client (but not the file, of course) and then just re-download the torrent-file at release and save it over the image you already have. Then your client will check what parts you have already and download the rest, and then you can help seed.

But I suppose it’s really not any more efficient than just downloading via bittorrent at release date. The protocol is made to share load. 🙂

Via jigdo, you still burden the central servers with whatever rest you need to get. Why not let the users help out? Bittorrent is the way to go.
