17 April

• 09:00 midom: fixed broken webster replication, caused by table bugs at database bugs
• 06:45 brion: fixed symlinked php.ini on srv2, srv3
• 00:00 midom: reformatted suda data area from xfs to ext2, brought into MySQL service for enwiki only

14 April

• 03:20 brion: eowiki lucene search live! others building...
• 02:45 brion: started lucene index builds for eowiki, ruwiki, dewiki
• 02:15 brion: lucene search live for meta
• 01:45 brion: restarted meta search build, as it was pulling from wrong db. whoops!

13 April

• 23:51 brion: noticed some spam coming in on bugzilla. hacked rel="nofollow" into comment processing, removed the comment, and disabled the account used to post it.
• 22:40 brion: starting lucene index builds for metawiki and some other wikipedias
• 00:08 brion: removed Apache-Midnight-Job from avicenna crontab

12 April

• 23:50 brion: vincent and avicenna are sharing LuceneSearch burden.
• 20:00 brion: Chad fixed vincent, which is now running lucene. Isidore lucene stopped, it's going to be squid soon. Will take over an apache for additional search capacity.
• 13:30 brion: lucene search turned on for en with slightly old index file, daemon running on isidore
• 10:30 brion: gcj on isidore seems horked; index rebuild is much too slow (eta 18 hours) so stopped it. uploading an index from home, and building mono for further testing.
• 10:00 midom: holbach restored.
• 08:55 holbach seems to be deadish
• 08:50 brion: started lucene index build on isidore
• 05:50 brion: vincent doesn't seem to be coming up again, will need to be kicked.
• 05:20 brion: upgrading vincent to 2.6 kernel hoping to resolve threading/memory issues w/ MWDaemon
• 02:10 brion: rebooting srv6 due to zombie squid eating port 80

11 April

• 23:05 kate: experimenting with making an en.wp image dump using trickle (cvs: /tools/trickle/)
• 08:00 midom: broken replication (by chineese scammer) on bacon, fixed by "use otrs; repair table article" - myisam tables are evil, aren't they?

10 April

• ~23:00: kate: upgraded squid to STABLE9+patches (see squid builds) + restarted all squids.
• mark: All squids are running with too few FDs (1024), and if noone replaces all daemons by the new one Kate just built, we may have a problem tomorrow during peak hours...
• 19:15 midom: srv7 is now in squid service
• 19:07 brion: MWDaemon's memory usage got high enough it started swapping. Hung connections ate up apaches and hung the site until it was restarted.
• 5:30 brion: lucene search server active for en.wikipedia.org, running on vincent.

9 April

• 15:45 midom: dropped thttpd (as it was using 32bit mmaps) on dumps in favor of lighttpd. It has superb performance, serves 3500hits/s under ab and served 70MB/s from benet in small reqs... Extreme recommendations for using lighttpd for image uploads.
• 10:15 brion: running lucene search indexer on vincent (pulling enwiki from benet).
• 05:25 brion: added additional is rcbots to #is.wikipedia for tionary/books/quote

8 April

• 16:00 midom: redirected http://download.wikimedia.org/ to benet, misses tomeraider and uploads...
• 13:00 Tim: switched to Mark's squid binary on the French squids

7 April

• Mark, Tim: implemented Multicast HTCP purging on all FL apaches/squids. French Squids still need a binary replacement.

6 April

• 21:44 mark: Put port gi0/26 on csw1-pmtpa into trunking mode: vlans 1-2 only, with vlan 2 being the native vlan, no LACP negotiation
• 11:30 midom: benet put into dump operation
• 10:55 brion: reinstalled PHP on zwinger and apaches, compiled with memory limit and mbstring options enabled. This was left out when upgrading to 4.3.11.
• 2:40 brion: added NetCabo proxies to trusted proxy list (inconveniently shared by Jorge and a Nazi vandal on pt.wikipedia.org)

4 April

• 15:30 jeluf: disbaled logging of upload.wikimedia.org
• 15:15 midom: yet another image server overload. rotated 30G upload.wikimedia logfile, could be fragmentation overhead.
• 12:00 midom: moved log_bin.0[0123]? (40G worth of binlogs) from ariel to khaldun/avicenna backup/arielbinlog, reclaimed some master disk space.
  • Do we need those binlogs for anything?
• 07:48 Tim: Started memcached on browne, it was in the list but not running. Fixed startup scripts. Noticed that browne can't contact albert on 10/8, modified yum.conf accordingly.

3 April

• 18:25 midom: extended public IP address range (now: 12 addresses)
• 17:50 midom: srv5 joined service as squid.

1 April

• 22:30 midom: Enabled recentchanges-based watchlist hack. Servers go faaaast.
• 23:15 brion: set default block expiry to 1h on dewiki by request of various admins
