IP Renumbering of the complete Toolserver cluster
by Marlen Caemmerer 02 Apr '13

02 Apr '13

Hello, Toolserver needs a complete change of the officially assigned IP addresses. Every accessible service will be involved. This involves several maintenances that will cause interruptions. The maintenances will also cause interuptions for OSM. To see if everything comes up correctly reboots will be necessary on all regarding servers. I will start with parallel IP setup at the load balancers/head nodes damiana and turnera. I will do this next Thursday, 28th March 20-22 h UTC. The next maintenances will involve the login servers, web and mail servers. They will happen at Friday, 29th March 20 - 22h UTC and Sunday, 31th March 20 - 22h UTC. I hope everything will work after that. Cheers nosy/Marlen

Maintenance for sql-s1-rr, sql-s2 and sql-s5-user
by DaB. 29 Mar '13

29 Mar '13

Hello, for a kernel-update I hereby announce downtime of sql-s1-rr-a, sql-s2 and sql- s5-user for tomorrow FRIDAY, 22:30 UTC. The downtime of each host will be 20-40min. Not affected will be sql-s5-rr. sql-s1-rr will be switched to rosemary so no downtime there too, but sql-s1 will be slower. See [1] for details. Sincerely, DaB.

Interruption of database-connections tomorrow
by DaB. 21 Mar '13

21 Mar '13

Hello all, for a config-change at our sql-load-balancer (that's the software-thing that converts something like "sql-s2-user" to the real server) I hereby announce a maintenance-window for tomorrow, WEDNESDAY, 20:05 UTC. During the downtime no connections to the databases will be possible, running database-queries will be aborted. If all works correctly the downtime will be less than 1 minute (just the restart of the service), but just to be sure calculate with 1h of downtime. You can follow the process at [1]. Sincerely, DaB. [1] https://jira.toolserver.org/browse/MNT-1308 -- Userpage: [[:w:de:User:DaB.]] — PGP: 0x2d3ee2d42b255885

ts.wikimedia.org cleaned up
by Marlen Caemmerer 19 Mar '13

19 Mar '13

Hello, the ancient subdomain ts.wikimedia.org has been removed. All services are reachable and as far as I know used anyway via toolserver.org but if you still use one of the names in your tools feel informed. Regards nosy

/tmp is not a waste dump
by DaB. 18 Mar '13

18 Mar '13

Hello all, few minutes ago I had to clean ortelius' /tmp again because it was nearly full (there is up to 13GB space). Using temp-files is a great thing and we all know that clean-up is boring stuff – but please: If you can not make your tools clean after them self then YOU have to clean up for them from time to time. /tmp at ortelius contains over 9000 small files at the moment – I VERY doubt that most of them are still needed. So please look what is still needed, fix your tools and/or write a cleaning-script. Otherwise I have to write a system-wide script that will delete all files that are older than x days. Sincerely, DaB. P.S: It is totally ok for Operators to delete files in /tmp if the space becomes tight. -- Userpage: [[:w:de:User:DaB.]] — PGP: 0x2d3ee2d42b255885

Re-Setup of thyme (sql-s1-rr)
by DaB. 14 Mar '13

14 Mar '13

Hello all, as announced the s1-cluster will be the next for re-setup. It will begin with thyme which handles sql-s1-rr at the moment. The re-setup of thyme will begin today evening or tomorrow and will take the whole weekend. During the time rosemary will handle sql-s1-rr (and sql-s1-user), so no problems should occur. Somewhen next week I will move over the user-databases than to re-setup rosemary – that will cause some read-only-time; I will send another mail for that. You can follow the progress at [1]. Sincerely, DaB. [1] https://jira.toolserver.org/browse/MNT-1305 -- Userpage: [[:w:de:User:DaB.]] — PGP: 0x2d3ee2d42b255885

12 Mar '13

Hi! Just a short note to remind you of the upcoming MediaWiki Hackathon in Amsterdam: http://www.mediawiki.org/wiki/Amsterdam_Hackathon_2013 Marc Pelletier, Sumana Harihareswara, me and *many* others will be there to meet you: We'll give a status update and a migration workshop for tool developers. The existing documentation will be updated on-the-fly. If you want help to get started at the Hackathon, please *get your Labs Account beforehand*. Here is how: https://wikitech.wikimedia.org/wiki/Help:Contents https://wikitech.wikimedia.org/wiki/Help:Getting_Started If you happen to be from Austria, you might still want to apply for a travel scholarship from Wikimedia Austria: https://www.wikimedia.at/content/stipendien-f%C3%BCr-den-amsterdam-hackatho… (in German).

Introduction: Operators (was: Adding more roots)
by DaB. 04 Mar '13

04 Mar '13

Hello all, after our discussion about more roots I got the impression that for some of you the topic of more roots is quite urgent. To be honest I feel not very well to just add a few roots at the moment. So I thought a compromise and created a new user-group: Operators [1]. Operators have a limited set of advantage rights – enough to help the roots and do every-day-jobs, but not enough rights to have access to sensible data (so no approval from WMDE or WMF is necessary). For testing I gave operator-status to the following people: Merl, who manage SGE already, Danny_B, who manage the user-store already, and Platonides who volunteered. There will be more in the future, but at the moment these 3 will do. In the new group the operators can collect experience while helping the users and the TS. And the roots can see who could get root-status someday and who not. The group is also a good place for users who like to help the TS, but can not invest the same amount of time like a root. So let's see if this solution works. Sincerely, DaB. [1] https://wiki.toolserver.org/view/Operators -- Userpage: [[:w:de:User:DaB.]] — PGP: 0x2d3ee2d42b255885

Reboot of the linux-userland-server this evening.
by DaB. 02 Mar '13

02 Mar '13

Hello all, for another kernel-update I have to reboot the linux-userland-boxes again. The reboot will happen TODAY, 20:00 UTC. The reboots will happen (again) sequentially in 15min intervals. SGE will migrate/restart your jobs to other servers during the downtimes. You can follow the progress at [1]. Another news from the linux database-servers (sql-s2 and sql-s5-user): I still try to find the optimal configuration. For this I have to restart mysql every few hours to bring changes live. I try to keep the downtime there at a minimum, but I guess slow and very outdated databases helps no one. Sincerely, DaB.

Workshops at the Amsterdam Hackathon
by Silke Meyer 02 Mar '13

02 Mar '13

Hi! We've been thinking about what skills current toolserver users could need when migrating to Labs. The upcoming Hackathon in Amsterdam is a good opportunity to offer workshops. As Tool Labs won't be ready by then, we thought about concentrating on software toolserver users are used to that won't be available (or won't be the default) in Labs. Possible topics: * git for svn users. * Or: Switching from Solaris to Ubuntu. * Or: Differences between Jira and Bugzilla. * Your ideas / needs here... To plan activities for Amsterdam, it would be good to know if you would potentially take part in such a workshop and what topic it should cover. So, as a *potential participant*, please let us know what you need! If you are interested in *offering such a workshop to others*, please let me know, too, and I'll organize it. Have a nice weekend!
