Migrating to Community-driven Infrastructure

Introduction
[up to date as of 2013-02-08] 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.

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.

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: Depending on option chosen, we might or might not keep the SuperMicro.
 * 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)

[2013-02-17] Hildon Foundation board has agreed on following IPHH and keeping OSUOSL open as an alternative if something with our "plan-A" goes awry. Tech staff wholheartedly agrees and will act occordingly, sending iron to IPHH/Falk 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.

Falk's mail forwarded form IPHH to HiFo: Hi everyone,

these are the details, what IPHH is willing to offer us.

Best regards,

Falk

Hosting migration timing plan: https://docs.google.com/spreadsheet/ccc?key=0AuQnrvWRbTtzdFhERzlDbEp0eVNQQTdfNWpQbzdIT0E&usp=sharing

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.

This page is intended as a central place where status and other operational information can be gathered.

Plan for migration / Timeline

 * Friday, 22.2. (falk)
 * Rack Hardware @ IPHH - Hardware is racked
 * Install base system (CentOS 6.3 with patches from xes)


 * Saturday, 23.2. (xes/falk)
 * Start migrating repository.m.o
 * Start migrating VMs with static data


 * ... (hidden DNS master set up)
 * sync databases, switch DNS entries

VMs we need to migrate:

Networks
We have 2 /28 Subnets (213.128.137.0/28 and 213.128.137.16/28)

Networks are configured as follows:

IP Plan for vlan 1

IP Plan for vlan 2

IP Plan for vlan 3

Disk Layout of blade-[ab]
Both disks have the following partitioning:

RAID1 Volume for /boot (/dev/md0), consisting of /dev/sda1 and /dev/sdb1 (200M)

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.

Tips & Tricks for migration
Copying:

Create an image on vmhost fallocate -l 200g image.img or, in case fallocate is unavailable dd if=/dev/zero of=image.img bs=1 count=1 seek=200G

Attach as loop-device losetup -f image.img (find the loop-device and create a filesystem on it)

Copy stuff tar --create -p -j --one-file-system. | pv -br | ssh root@host 'cd /mountpoint ; tar xpj ' or cd / ; rsync -arvSxz. root@host:/mount/point

Inventory (obsolete, please update)
As a first step we try to gather information about the present infrastructure at *.maemo.org. This "inventory" is intended to provide an overview about all components of the infrastructure as well as to provide information that will later on aid during the actual migration.

Currently the following topics are considered important for the migration:


 * Legal Issues (Names, Trademarks, Domain Names, etc.)
 * Infrastructure (Web Site, Forum, Wiki, Autobuilder, Mailinglists, Garage, etc.)

What is the state about the name "Maemo"?
"... Maemo is currently a registered trademark of Nokia and the domain name is owned by Nokia.

Who owns "maemo.org"?
Negotiations about domain ownership still ongoing between Hildon Foundation board and Nokia (2013-01-20), if community can't get control over the DNS, we might revert to maemocommunity.org.

We're planning to ask Nokia to allow a hidden primary for maemo.org, that we will host on a persistent VM (dns) sponsored by Nemein (thanks Eero! :-D ). The purpose is to allow swift changes of IPs under maemo.org without bothering Nokia's DNSmaster, as long as the domain still belongs to Nokia. Once the domain will get transferred to HiFo, this will become less useful but also not exactly any problem. in 6 months or so we can consider tearing down the hidden primary and manage our domain directly.

What is needed for the community to run maemo.org?
TMO forums donated to Hildon Foundation: http://maemo.org/community/board/tmo_forums_donated_to_hildon_foundation/

What are the costs?
Nokia paid for hosting until end of February. Current (2013-01-30) interim config (VM on Nemein's xen-grid) will cost 1300EUR/month for the VM, plus 2200EUR/month for the maintenance. For the colocation rackspace, traffic, energy etc of the iron(s) Nokia donates to community there will be another 500+EUR/month. All excl VAT.

At end of February we hope to drop the xen-grid VM since they shall run in a virtualization on our iron by then.

If you're willing to donate, please visit http://hildonfoundation.org/support/

What about the personal information of the users?
Please refer to the privacy policy posted on the website. If you want info about what's the data stored about you inside *maemo.org, or want this data / your account getting permanently deleted, please contact council@maemo.org

Operational Platform
For now (2013-01,02) all services are implemented as VM running on Nemein's xen-grid. Plan is to migrate those VM to a virtualization installed on the serevrs (see below) that Nokia donates to the community. This hardware is located at Nemein office right now (2013-02-16) and should get shipped to iphh.net in Hamburg on Monday 2013-02-18.

List of hardware Nokia will donate to HiFo, according to Nemein's plans. [2013-02-08]

Forum (talk.maemo.org)
Unlike the other services, talk.maemo.org is not behind the endian firewall. Maintenence access is not via test jumpserver.

Software: vBulletin licence: Unlimited duration, no upgrades included, acquired on 2012-20-12

Scratchbox
Scratchbox is also sponsored by Nokia. (Please verify?) Scratchbox is required for running the Fremantle and Harmattan SDK.

Currently there's a VM on Nemein's xen-grid named "scratchbox", but state of the case is unclear.

Tracker for Sysops and Maintainers
This tracker is meant for maemo staff and affiliated only web frontend: roundup.fourecks.de/maemo/ mail access (read docs!): maemo-issue AT fourecks.de

Service Maintainers (please update/augment/fix)
(please don't usually pester maintainers directly! First try to contact council@maemo.org, we'll forward)

These are the Service Maintainers (in spe), for services like forum (tmo), wiki, bugs, etc. They are (generally) not sysops of the machines their service is running on.

Steering
council is in charge of any steering. Joerg Reisenweber got appointed for "maemo.org infra administration coordinator" and thus is the single point of coordination for any detail questions.

If you got any questions, suggestions, critics, whatever, please contact Joerg (DocScrutinizer) or any other of council members via IRC. or send a mail to council AT maemo.org. We're just community's proxies acting in best intention to do what's probably community's best interest. If you don't agree with what we do or have suggestions how we could do better, please holler. Best place: Friday 1800UTC IRC:(freenode.net)#maemo-meeting
