'''please somebody does a major rework of this page, to a new wiki page like "community maemo.org infra - at IPHH" and clean out all the history data that doesn't give any useful info anymore. Also splitting off the autobuilder stuff into a separate page might help'''

Albeit Nokia's plans about discontinuation of maemo support been known since spring 2012, Nokia gave "Go" to Nemein (service provider on behalf of Nokia) for the real migration work not earlier than 2 weeks before christmas 2012.
-
Started to move stuff
+
As of January, 18th 2013 the *.maemo.org infrastructure has been consolidated from a 20+ physical servers (aka "irons") to current config and completely migrated to new locations independant of Nokia servers. This task been accomplished by Nemein. Talk.maemo.org forum been integrated with the other infra, many thanks to Nemein for donating the VM for that. Also many thanks to Nemein for this incredible piece of work done during times when others (as well as the guys there) usually are already away for winter holidays.

The current setup (see below) consists of around 10 Virtual Machines hosted by Nemein on their xen-grid. This is an interim solution. Nokia paid Nemein for this consolidation/migration and hosting until end of February.

Handing over control of servers still pending, right now (2013-01-30) it's still Nemein and affiliates to control that infra.

Please use Categories below for any future pages of this topic
+
Transfer of control over (*.)maemo.org DNS entries ("the domain") is still being negotiated between Nokia and HiFo, all DNS changes done so far been done by Nokia dnsmaster on Nemein's request
 +
 
 +
The plans of council and HiFo board so far are: kindly ask Nemein to have  *.maemo.org nicely bundled. We hope for this setup to be free of major known bugs (I.E. autobuilder working, repository working albeit maybe slow) when Nemein hands us the package.
 +
 
 +
[2013-02-08] Negotiations about direct migration to one of our 3 options (see below) are ongoing.
 +
 
 +
===further plans, state of migration===
 +
Further plans are to migrate again to some hosted root servers, either on a sponsor like http://osuosl.org/about-osuosl or to our own stuff we may rent from e.g. Hetzner.
 +
 
 +
[2013-02-08] currently we're in negotiations about 3 possible ways into future hosting:
 +
* osuosl (could provide VM or rootservers or CoLo [UPS server shipping: 48h:1200EUR, 7d:630EUR, +customs])
 +
* IPHH, a ISP in Hamburg. Falk contacted them and they are willing to offer CoLo basically free of charge. Of course we will put their name on our maemo.org frontpage to give due credit. HW service will be done by Falk. (costs ~300EUR for setup and HW upgrade, plus 50..300EUR for shipping the iron to Hamburg)
 +
* get own paid rootservers, like 2 of http://www.hetzner.de/en/hosting/produkte_rootserver/ex10 (costs ~300EUR/month, 400EUR setup)
 +
Depending on option chosen, we might or might not keep the SuperMicro.
 +
 
 +
[2013-02-17] Hildon Foundation board has agreed on following IPHH if the contract is good and keeping OSUOSL open as an alternative.  Sending iron to IPHH on 2013-02-18/19, and also negotiating with OSUOSL about how a possible migration to them would look like so we get a decent checklist in case we need it.

Hosting migration timing plan:

 +
 
 +
 
 +
Alternatives - however obvious - for the above plans have been discussed with Nemein and HiFo and are not feasible. E.G. there was no way we could get the money instead of the server iron hardware. Sustaining the current xen-grid based VM hosting would be ~1500EUR per month plus a basically not evadable 2200EUR on top for maintenace. We want to switch away from that by all means, thus the 2nd migration.

RAID1 Volume /dev/md1 consisting of /dev/sda2 and /dev/sdb2 (around 970G)

The RAID1 Volume contains a physical LVM volume.

We only have one VolumeGroup (vg_blade[ab]), which has LogVol00 with 20G as root volume, LogVol01 with 2 Gig as swap and vmstore with the rest as VM Storage mounted on /vmstore.

 +
maemo autobuilder setup
 +
 
 +
autobuilder consists of multiple VMs
 +
 
 +
=== drop VM ===
 +
this VM has /etc/passwd synchronised with garage and ~ folders mounted via NFS from garage
 +
 
 +
account synchronisation is handled by scripts running on garage VM and then sync is triggered using ssh and scripts in /usr/local/bin
 +
 
 +
packages are uploaded to /mnt/incoming-builder via SCP
 +
 
 +
=== garage VM ===
 +
this is the VM where stuff happens
 +
password/account sync to gforge/postgresql is done using
 +
*/10 *  * * *  root    /usr/local/bin/add_groups_users_git_ssh.sh > /tmp/add_groups_users_git_ssh.log dev/null 2>&1
 +
this also updates ~/.ssh/authorized_keys
 +
 
 +
garage also handles web extras-uploader (/var/lib/extras-assistant/) - package is uploaded and then moved to the same folder as packages uploaded to drop and then chowned using
 +
 
 +
/var/lib/extras-assistant/bin/copy_package_files_to_autobuilder.sh
 +
 
 +
A lot of jobs on garage VM is done using local root crontab (/var/spool/cron/crontabs/root)
 +
 
 +
after package is uploaded it's processed by buildME
 +
 
 +
buildME runs as builder user and it's started from cron every minute
 +
* * * * * builder /home/builder/buildme
 +
 
 +
buildme is configured using /etc/buildme.conf
 +
 
 +
buildme takes care of couple things
 +
* verify that .tar.gz and other files are correct (checked using checksum from .dsc file)
 +
* select free destination (buildme can handle parallel builds on multiple hosts/users)
 +
* scp all required files to selected destination
 +
* start sbdmock on the destination
 +
* copy results back and resulting .deb to repository incoming folder (result_dir = /mnt/builder/%(product)s and repo_queue = /mnt/incoming/extras-devel/%(product)s/)
 +
* send emails to list and user uploading package
 +
 
 +
=== builder VM ===
 +
 
 +
this VM has standard installation of scratchbox with no targets configured (it's not required for sbdmock)
 +
 
 +
when sbdmock is started it cleans up old build folder, creates new target and prepares build enviroment and then runs dpkg-buildpackage
 +
 
 +
sbdmock also generates logfiles that are parsed by buildme
 +
 
 +
=== repository/stage VM ===
 +
 
 +
this is where repository management happens
 +
*/2 * * * *    repository      /home/repository/queue-manage-extras-devel.sh
 +
*/5 * * * *    repository      /home/repository/queue-manage-extras.sh
 +
*/5 * * * *    repository      /home/repository/queue-manage-community-testing.sh
 +
*/5 * * * *    repository      /home/repository/queue-manage-community.sh
 +
 
 +
those scripts (and scripts inside /home/repository/queue-manager-extras) check for new packages in repository incoming folder and then move those to /var/repository/staging, regenerate Packages
 +
 
 +
(using sums that were previously cached) and sign it if required and then if any changes happened
 +
#touch .changed file, so we know that we need to sync to live
 +
touch /var/repository/staging/community/.$dist.changed
 +
 
 +
this file is then checked by
 +
1003    10634    1  0 Mar18 ?        00:00:00 /bin/sh /usr/local/bin/packages/rqp.sh
 +
started by /etc/init.d/repository-qp
 +
 
 +
this script starts rsync when required to sync to live repository
 +
 
 +
this script also starts repository-queue-proc.php that processes repository updates coming from midgard (old package cleanup and promotions)
