The beta cluster wikis are working again. It turns out that there was some confusion when moving/removing servers because of implementation drift between our production clusters and the beta cluster. Before the move to the new region we had both "memc*" and "redis*" servers in the beta cluster project. The "memc*" servers are the equivalent of our production "mc*" servers. In production the "mc*" servers run both memcached and redis services. In the beta cluster our "memc*" servers were only providing memcached and the configuration relied on the "redis*" servers for session storage. The "redis*" servers were removed while migrating virtual machines to the eqiad1-r region under the assumption that they were legacy servers from the time when we used redis as storage for the job queue. The fix was to setup the "memc*" servers with both memcached for arbitrary data caching and redis for session storage. If you are interested in the gory details see notes left on https://phabricator.wikimedia.org/T210030.

[Wikitech-l] Problem importing images
Hi all, I've installed a new 1.31 and imported content from an xml dump using importDump.php which included file descriptions, then imported the images from a directory of files using importImages.php. About half of the files have imported successfully, but the other half say the image is not found when I go to the image page in the wiki. i can see the image in the proper place in the upload directory so it has imported properly. If I try and re-upload the image manually I can't because it says an exact replica already exists, but click on that link to the already existing one still says "No file by this name exists, but you can upload it". I've tried running all the related maintenance scripts such as rebuildImages.php with no success :-( Any ideas? Thanks, Aran ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
Re: [Wikitech-l] Thank you Tuesday
1. Thanks Kunal for starting this thread. 2. Thanks to Andrew for migrating beta cluster to a new region 3. Thanks to Krenair for a ton of help debugging beta cluster problems the past couple of days.

Re: [Wikitech-l] Deployment-prep (aka 'Beta') services will be unreliable this week
So we've made some headway in resolving all of the inevitable issues that cropped up after migrating a lot of cloud instances to all new infrastructure and assigning a new IP to each of them. Many Thanks to Krenair and Andrew for all the great work you've been doing to get things back to normal. Despite each of our efforts, there is still a configuration error preventing MediaWiki from working in beta. I've been stuck for several hours now but I'm hopeful that this is the last major issue and I'm sure it's simple for someone who understands MediaWiki internals better than I do. Unfortunately I'm completely stumped so I could really use some help from someone who understands the configuration of MediaWiki session storage and the underlying object cache. The problem is described in https://phabricator.wikimedia.org/T210030 so I won't repeat it here. I'll simply appeal for those of you who know something about how "BagOStuff" is configured, please take a look at T210030 and point me in the right direction. Thanks in advance for taking a look. I apologize for the inconvenience caused by this unfortunately unavoidable interruption of service.
