Upgrade to MariaDB 10.2
by Huji Lee 02 Jun '19

02 Jun '19

Hi all, Does anyone know when we will be upgrading the Clouds replica DBs to MariaDB 10.2? I am asking mainly because we are on 10.1.33, 10.3 is now out, and since 10.2 support for CTEs (WITH statements) has been added which is very handy. Thanks, Huji

[Cloud-announce] Dumps NFS maintenance - 2018-12-03 @ 1700 UTC and 2018-12-07 @ 1700 UTC
by Brooke Storm 07 Dec '18

07 Dec '18

On Monday, December 3rd, 2018 at 1700 UTC, we will be rebooting one of the two dumps NFS servers (labstore1006.wikimedia.org <http://labstore1006.wikimedia.org/>). This should cause rising load issues briefly, but should be quick enough that failing over services is likely to not be helpful. We will be failing over the web service before that time and failing it back before rebooting the partner server (labstore1007.wikimedia.org <http://labstore1007.wikimedia.org/>) on Friday, December 7th at 1700 UTC. This should not interrupt services to dumps.wikimedia.org <http://dumps.wikimedia.org/> (the site hosted on these systems) since that should be failed over to the non-rebooting partner.

[Mediawiki-api-announce] DEPRECATION: Action API uncaught exception error codes
by Brad Jorsch (Anomie) 27 Nov '18

27 Nov '18

Currently the codes for uncaught exceptions include the class name, for example "internal_api_error_ReadOnlyError", or "internal_api_error_DBQueryError", or possibly something like "internal_api_error_MediaWiki\Namespace\FooBarException". As you can see in that last example, that can get rather ugly and complicates recent attempts to verify that all error codes use a restricted character set. Thus, we are deprecating these error codes. In the future all such errors will use the code "internal_api_error". The date for that change has not yet been set. If a client for some reason needs to see the class of the uncaught exception, this is available in a new 'errorclass' data property in the API error. This will be returned beginning in 1.33.0-wmf.8 or later, see https://www.mediawiki.org/wiki/MediaWiki_1.33/Roadmap for a schedule. Note that database errors will report the actual class, such as "MediaWiki\rdbms\DBQueryError", rather than the old unprefixed name that had been being maintained for backwards compatibility. Clients relying on specific internal error codes or detecting internal errors by looking for a "internal_api_error_" prefix should be updated to recognize "internal_api_error" and to use 'errorclass' in preference to using any class name that might be present in the error code. In JSON format with errorformat=bc, an internal error might look something like this: { "error": { "code": "internal_api_error_InvalidArgumentException", "info": "[61e9f71eedbe401f17d41dd2] Exception caught: Testing", "errorclass": "InvalidArgumentException", "trace": "InvalidArgumentException at ..." }, "servedby": "hostname" } With modern errorformats, it might look like this: { "errors": [ { "code": "internal_api_error_InvalidArgumentException", "text": "[61e9f71eedbe401f17d41dd2] Exception caught: Testing", "data": { "errorclass": "InvalidArgumentException" } } ], "trace": "InvalidArgumentException at ...", "servedby": "hostname" } -- Brad Jorsch (Anomie) Senior Software Engineer Wikimedia Foundation _______________________________________________ Mediawiki-api-announce mailing list Mediawiki-api-announce(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/mediawiki-api-announce

[Cloud-announce] ToolsDB Maintenance - 2018-11-27 @ 1730 UTC
by Brooke Storm 27 Nov '18

27 Nov '18

ToolsDB will be undergoing maintenance and updates, Tuesday, November 27th at 1730 UTC to 1800 UTC. Actual outage times should be fairly brief, but during this time the database will be taken offline and the system rebooted. Due to the expected brief nature of the outage and the fact that some tables are not replicated (see https://wikitech.wikimedia.org/wiki/Help:Toolforge/Database#ToolsDB_Backups… <https://wikitech.wikimedia.org/wiki/Help:Toolforge/Database#ToolsDB_Backups…>), we are not planning on failing over to the replica at this time.

[Cloud-announce] CloudVPS network maintenance 2018-11-27 @ 17:30 UTC
by Arturo Borrero Gonzalez 27 Nov '18

27 Nov '18

Hi, next Tuesday, 2018-11-27 @ 17:30UTC we will reboot the labnet1001.eqiad.wmnet server for maintenance and security updates. This server provides virtual networking services for CloudVPS in the main deployment (the old one, different from the eqiad1 deployment). We won't be doing any failover prior to the reboot for operative reasons (we measured the failover downtime is longer than the actual reboot time). The impact of this brief reboot downtime will be: * all VMs in the main CloudVPS deployment won't have network connectivity * ongoing network connections (downloads, uploads) will fail and will have to be restarted * cross connectivity between VM instances in the main and eqiad1 deployment won't be possible Thanks for your understanding, and let us know any issues you may find after the reboot next week. _______________________________________________ Wikimedia Cloud Services announce mailing list Cloud-announce(a)lists.wikimedia.org (formerly labs-announce(a)lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/cloud-announce

[Cloud-announce] OSM database reboot next Tuesday 2018-11-20 at 17:30 UTC
by Arturo Borrero Gonzalez 20 Nov '18

20 Nov '18

Hi, next Tuesday 2018-11-20 at 17:30 UTC we will be rebooting the OSM database (part of our data services) for maintenance and security updates. In concrete the labstore1006.eqiad.wmnet (osmdb.eqiad.wmnet) server will be rebooted. The other server in the cluster, labstore1007.eqiad.wmnet has been rebooted already, but we won't be doing any pre-failover for operative reasons. Apologies in advance for any inconvenience, and please let us know any issue you may find after these operations. _______________________________________________ Wikimedia Cloud Services announce mailing list Cloud-announce(a)lists.wikimedia.org (formerly labs-announce(a)lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/cloud-announce

[Cloud-announce] tools-bastion-02 aka tools-dev downtime on Tuesday
by Andrew Bogott 20 Nov '18

20 Nov '18

Hello! I need to shut down the tools-dev host in order to move it to a different server. The downtime will be brief, but in the meantime I recommend people move their work to a different bastion (e.g. tools-login.wmflabs.org) in order to avoid interruption. This will happen on or near 15:00 UTC on Tuesday, 2018-11-20. I'll also send alerts to sessions on the bastion prior to the shutdown. -Andrew _______________________________________________ Wikimedia Cloud Services announce mailing list Cloud-announce(a)lists.wikimedia.org (formerly labs-announce(a)lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/cloud-announce
