Update/upgrade MD's from core not internet?

[tompin2]

Hi to all,

Is it possible to update/upgrade all the MD's from the core?.  If I have several MD's if i want to keep them updated, all of them have to download from the internet the packages.  Since they all boot up from the core, which means that they all should be at the same version of the core, would be faster to set up all the MD's to do the apt-get update/upgrade  from the core?
My apologies if this is a dumb question, I just couldn't find an answer  on the forum search

Cheers,

T

I do this with SSH.

If you are on your core, you can do...

Code: [Select]

sudo su -
ssh moonXX
...where XX is the device number of the MD (find this out in web admin).

Alternatively, if you are on another machine on the internal network, you can do...

Code: [Select]

sudo ssh root@192.168.80.1
ssh moonXX
...assuming you are using the standard internal IP of 192.168.80.1.

Note that it is necessary to SSH into the core as root because if you SSH in with your user ("purps" in my case), you won't have any admin privileges once you have SSHed into the MD.

More information about logging in etc here http://wiki.linuxmce.org/index.php/Logging_In

Cheers,
Matt.

EDIT: I just re-read your post. Don't think I answered your question did I. Why don't you want to download from Internet? Do you have monthly download limits or something?

tompin2,

atm there is no defined way to update the MDs from a single (non Internet point). One way of achieving it, would be to copy the contents of the core's /var/cache/apt/archive directory into each MDs /usr/pluto/deb-cache dir, and rebuild the Packages file in the /usr/pluto/deb-cache directory, remove all the other sources from /etc/apt/sources.list except the file entry pointing to deb-cache.

Try if you can get it working, and maybe even write a small script, doing the steps for you one after the other.

Good luck.

[tompin2]

Thanks to all, Im not good in linux but I will give it my best.  Maybe I find something usefull for all.  The way I see it is that I see an option under webadmin that you could just click to the MD page and update/upgrade, maybe it is not possible, maybe it is.  For now, a good script should be a good progress.  I hope I get the knoledge soon to make my own script and share it to all.

I will Keep all posted.

Should work. Presumes MDs are on. Testing now. Can probably make a button in computing pretty easy. Will get back.


*I'm an idiot... that first one will exit after first moon unit is upgraded.

you should backup sources.list before overwriting

Can probably make a button in computing pretty easy.

Isn't there already a button under advanced called "upgrade" or something similar?

[l3mce]

There is... but I believe this does not address MDs. I am thinking of just a global update button you can click if you want. I am also going to tar all of the md directories on the core, and try and use the systems db backup in case things go terribly wrong.

hari: done

Everyone else: completely redoing this and chrooting the MDs for upgrade. Ignore that first stumble into the idea. And the ticket has been closed. So much for a quick attack.

[Marie.O]

The ticket got closed, because we already have ticket 341 which does the same thing, and which already has most of the functionality in place (except the part of disabling the daemon autostart while in chroot). l3mce will take what we have, and add a few things to it.

That is where I am. Here is the output after upgrading... (note core had already been upgraded, and output was huge due to database upgrade)

I clearly have a couple things to fix, and a few things I already have.

***The latest script is untested. I believe it works as desired. Will test shortly... including force closing to test the trap.

Great work!

An observation:

MDs already mount the core's /usr/pluto/deb-cache when they boot, for chroot upgrades the directory can be bound locally (mount --bind /usr/pluto/deb-cache /usr/pluto/diskless/XX/usr/pluto/deb-cache) on the core, negating the need to copy the .debs to the /usr/pluto/diskless/* locations.  Duplicating the contents of the core's /usr/pluto/deb-cache for each MD is redundant and adds up to a huge amount of HD space.

Upgrade the core, then copy the contents of /var/cache/apt/archives/*.deb to /usr/pluto/deb-cache, run dpkg-scanpackages and gzip the Packages file.  Then all MDs can have access to the latest files.

Thanks for the feedback.

On my 810 install, the only files that exist in the cores /var/cache/apt/archives are ones which upgrade. This is possibly a result of something in the past I have done.

Yes... it took me a couple of rereads to understand, and a little poking around to confirm, but you are exactly right... and that cleans this whole process up. Thank you very much. MUCH better way to handle it. I didn't realize a lot of that... and now I don't have to edit that Packages file... yay.

That is so much cleaner. Will test in a few. Thanks again Phenigma! I have never used --bind before... I am presuming that I can umount the second directory in the bind when I am done with the process for each MD to avoid... weirdness.

Good stuff!  Yep, unmount using the dir listed 2nd in the mount command.

I noticed that you're altering the init/startup scripts on the core instead of the MDs.  This needs to be done for an MD that is updated via chroot, but not ssh.  I'm attaching the version I tinkered with a little, it takes these things into account and should restore the original sources.list files.  I admit I'm only just learning about trap now as well.  I've tested it but not much.  Keep up the good work!

I also made a few changes...

My understanding was that I needed to address the scripts from the core, but expect you are correct. Thank you very much.
I do not understand:

Code: [Select]

mv /usr/pluto/diskless/$moonDir/usr/sbin/invoke-rc.d{,.lmce-update}or

Code: [Select]

mv /usr/pluto/diskless/$moonDir/usr/sbin/invoke-rc.d{.lmce-update,}
Though in the Diskless_CreateTBZ.sh which I was stealing some of this method from it worked similarly. I was just moving the damned files obviously.

Also, if the files exist (as we make fakes), will this methodology require a -f (force) move to avoid overwrite confirmation?

How does this look?

Other than not being as pretty as yours...
