Hello all, at Wednesday, 14th March, between 19:00 and 23:59 UTC we will have a maintenance-window. The most important change is the update of SGE, which will stop all planed and running SGE-jobs during the update. We will also try to use the new SAN-system for the first time and we will move the commons-database on rosemary to the SAN (for that we have to stop rosemary's MySQL). If this is successfull, I will dump the user-databases on thyme (for that I will switch thyme to read-only) and than import them into rosemary – as a preparation of the re-import of sql-s1 on thyme when the wmf provide us with a fresh dump. If we have enough time, we will extend the disc-size of z-dat-s4-a, which will cause a (short) downtime of sql-s4-user (sql-s4-rr will stay online). No other userland-software will be updated during the window, but we may install solaris-patches for the OS and system-services if we find the time.
Sincerely, DaB. -- Userpage: [[:w:de:User:DaB.]] — PGP: 2B255885
