Subject: [Wikitech-l] Deploying Swift for thumbnails next Mon-Thurs Feb 6-9
To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org>
Hi Everyone,
Next week we're going to switch the back end system that hosts thumbnail[1]
images. We have been using
ms5<http://ganglia.wikimedia.org/latest/?r=day&cs=&ce=&m=&c=Miscellaneous+pmtpa…>(a
Sun server running linux) to serve all thumbnails. We are switching
to Openstack
Swift <http://wikitech.wikimedia.org/view/Swift>, a clustered object
store. Though we have done testing and expect no problems, I want to
publicize the change so that if issues do appear, they are quickly directed
to the right place.
Here's the schedule:
* Monday Feb 6th: move 0.4% of all thumbnail traffic from ms5 to swift.
Only thumbnails with "/thumb/a/a2/"[2] in the URL will be affected.
* Tuesday: move 12.5% of traffic - thumbnails with "/thumb/a/" or
"/thumb/b/" will be affected
* Wednesday: move 50% of traffic - thumbnails with "/thumb/(a-f or 0 or
1)/" will be affected
* Thundlay: move 100% of traffic - all thumbnails will be served from Swift
Potential symptoms that might be related to this change on Monday:
* a thumbnail image with /a/a2/ simply fails to load
** try changing the number preceding 'px' to generate a different size
image[3]
* you delete an image and the thumbnail is still available
** try purging the cache[4] and see if that makes it go away
** try changing the number preceding 'px' and see what happens
* you move an image to a new name and it's still available at the old name,
when either the new or old name has /a/a2/ in the URL
** please provide full URLs for both the new and old names
If any of these things happen, or if something else odd happens with images
or thumbnails and you feel it might be related, please join #wikimedia-tech
in IRC and ping me (maplebed) or Aaron (AaronSchulz). If neither of us are
available or you would prefer to just leave us a message, add a note to
https://www.mediawiki.org/wiki/SwiftMedia/Issues. :) If things are
severely broken, you can ask someone in the #wikimedia-tech to page me.
Thanks for your help!

[1] In case you don't know what I mean by thumbnail images, I'm talking
about all URLs that start http://upload.wikimedia.org/ and have /thumb/ in
the path. When an image is uploaded to a wiki (or commons), Mediawiki
automatically generates scaled versions of the image. These are what I
call 'thumbnails'. Nearly every time an image is used in a wiki page it is
actually a thumbnail being used. Try going to any wiki page with an image,
right click on the image, and choose 'view image'. You'll get something
like
http://upload.wikimedia.org/wikipedia/commons/thumb/4/45/Liberty_Head_Nicke…
as the URL (this was taken from enwiki's featured article today)
[2] For example,
http://upload.wikimedia.org/wikipedia/commons*/thumb/a/a2/*Little_kitten_.j…
[6]
[3] For example,
http://upload.wikimedia.org/wikipedia/commons/thumb/a/a2/Little_kitten_.jpg/
*799px*-Little_kitten_.jpg
[4] Find the URL for the main image file (rearrange the URL to find the
original image - /wikipedia/commons -> commons.wikipedia.org) and add
"?action=purge" to the end of the URL (eg
http://commons.wikimedia.org/wiki/File:Little_kitten_.jpg?action=purge

Actually, just asking in #wikimedia-labs, there's an high probability
that someone with appropiate permissions will be there.

I want to let you know of a new feature we now have on Wikimedia sites.
Please publicize this to wikis, and ask them for suggestions and
criticism, and pass that information along to Max. Thank you.

Yesterday we deployed FeaturedFeeds[1] to the cluster (thanks,
Arthur!) Everything looks good so far, examples of feeds: [2], [3].
We haven't enabled feed links in the sidebar like on our staging wiki
at [4] - I wonder if we should enable them on opt-in or opt-out basis.
Overall, I'd apreciate your critics, comments, suggestions. Also,
please assist your local communities in seting up their feeds, especially
if you know less common languages.

"...the Wikipedia community has decided to black out the
English-language Wikipedia for 24 hours, worldwide, beginning at 05:00
UTC on Wednesday, January 18. The blackout is a protest against proposed
legislation in the United States —the Stop Online Piracy Act (SOPA) in
the U.S. House of Representatives, and the PROTECTIP Act (PIPA) in the
U.S. Senate— that, if passed, would seriously damage the free and open
Internet, including Wikipedia....."
We'll be disabling editing via the web service API. You can ask
questions regarding the planning in #wikimedia-sopa .

Subject: [Wikitech-l] Mailing lists server migration today

Hi,
Today I will be migrating the mailing lists from a very old server
(lily) in Amsterdam, to a new server (sodium) in our new Ashburn data
center. Mailman will be upgraded to version 2.1.13 along the way.
During the migration, mail will be delayed as all data will need to be
transferred to the new host. No mail should go lost, but no new mails
will be sent out during the process until done, and the web interface
will be unavailable. This shouldn't take more than one hour, if all goes
well.
I will report here when things should be back up and running.
Afterwards, please let us know of any new issues, in bugzilla or on IRC
(#wikimedia-tech). We don't expect any problems, but as with any
software upgrade or migration, this can't be guaranteed...
Thanks,

...and right after I sent this mail, I rebooted the new server once
more before starting the maintenance. But suddenly it refused to come
back up, or even reinstall. Likely the server has hardware issues.
Therefore the maintenance is canceled for today, until we've figured
out what the problem is. The migration will probably happen next week,
possibly using different hardware.
