== Introduction ==
+
I see, I spuospe that would have to be the case.
-
[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:
+
-
* 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.
+
-
 
+
-
Falk's mail forwarded form IPHH to HiFo:
+
-
<pre>
+
-
Hi everyone,
+
-
 
+
-
these are the details, what IPHH is willing to offer us.

Best regards,

-
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.

-
* DNS switchover should happened at 14.3., around 17:00UTC
+
-
* all VM got synced and are up and running. *old* should be out of business when DNS change propagated

==== 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
+
-
<pre>fallocate -l 200g image.img</pre>
+
-
or, in case fallocate is unavailable
+
-
<pre>dd if=/dev/zero of=image.img bs=1 count=1 seek=200G</pre>
+
-
 
+
-
Attach as loop-device
+
-
<pre>losetup -f image.img</pre> (find the loop-device and create a filesystem on it)
+
-
 
+
-
Copy stuff
+
-
<pre>tar --create -p -j --one-file-system . | pv -br | ssh root@host 'cd /mountpoint  ; tar xpj '</pre> or
+
-
<pre>cd / ; rsync -arvSxz . root@host:/mount/point</pre>
+
-
 
+
-
==== Stuff to do [2013-03-15] ====
+
-
 
+
-
* Implement a proper service monitoring for all machines and applications - nagios pending, http://monitor.maemo.org/ganglia/
+
-
* Setup a common policy for root/user accounts and sudo permissions
+
-
* Change root-passwords - done
+
-
* Make SSH root-login key-only - done?
+
-
* Find out, what to sync for final migration - done
+
-
* Configure internal DNS server in /etc/resolv.conf
+
-
* Coordinate DNS setup with Nokia - partially done
+
-
* Consolidate Databases - WIP
+
-
* Add disks to system - done, 4TB on blade-a
+
-
* Setup bugtracking system for infrastructure - done: roundup?
+
-
* fix NFS mounts - WIP
+
-
* update VMs to 3.2.0-38
+
-
 
+

==== Problems we walked into ====
+
-
 
+
-
===== Machines throwing their network away =====
+
-
 
+
-
Apparently, XEN has issues if a vm sends too many/too large network packets.
+
-
 
+
-
http://lists.xen.org/archives/html/xen-devel/2013-01/msg00198.html
+
-
has an interesting read about that problem.
+
-
 
+
-
Symptom:
+
-
 
+
-
  xenbr1: port 8(vif51.0) entered forwarding state
+
-
  vif vif-51-0 vif51.0: Too many frags
+
-
  vif vif-51-0 vif51.0: fatal error; disabling device
+
-
  xenbr1: port 8(vif51.0) entered disabled state
+
-
 
+
-
in dmesg
+
-
 
+
-
Temporary fix: Disable all offloading on eth0
+
-
 
+
-
  for i in rx tx sg tso gso gro lro; do
+
-
          ethtool -K eth0 $i off
+
-
  done
+
-
 
+
-
Source of this problem:
+
-
 
+
-
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/include/linux/skbuff.h?h=v3.3.1&id=9d4dde5215779f4099730194ad30624fdba3d8b2
+
-
 
+
-
 
+
-
We fixed that problem on our machines by ensuring dom0 and domU use same MAX_SKB_FRAGS
+
-
 
+
-
== 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.)
+
-
 
+
-
 
+
-
== Legal Issues ==
+
-
 
+
-
=== 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 [http://fengnet.com/book/DNS.and.BIND.5th.Edition/dns5-CHP-16-sect-1.html] 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.
+
-

=== 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)

== Unsorted Hints ==
+
-
=== ssh access ===
+
-
All legacy accounts got ported to new infra.
+
-
 
+
-
Access to any VM is via plain direct ssh:
+
-
ssh <user>@<VM>.maemo.org
+
-
 
+
-
=== backup ===
+
-
we're doing backups to the 4TB auxiliary storage on blade-a, using backupPC:
+
-
ssh -L8088:localhost:80 blade-a
+
-
konqueror http://localhost:8088
+
-
backup-master is Falk
+
-
 
+
-
talk VM sysop (chem|st) has access to it and control over own backups, via ssh confic on blade-a:
+
-
command="sleep 1d",permitopen="127.0.0.1:80"  <ssh-pubkey>
+
-
 
+
-
== 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

+
-
== Autobuilder and friends ==
+
-
 
+
-
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
+
-
 
+
-
