October 1[edit]

  • yarrow river: started s1 import from vandale dump
  • yarrow river: confirmed bad disk in yarrow's array, channel 3, id 12:
Medium error during read
ASC: 0x13   ASCQ: 0x0
Repairing hard error on 127914882 (7962/84/60)...Warning: Block 127914882 zero-filled.
The new block also appears defective.
  • yarrow river: rebooted to add new lun for possibly failed disk, now running media scan
  • zedler river: rebooted accidentally, mysqld recovers
  • yarrow river: ran a RAID5 parity check on the array, one drive (channel 3, id 12) reported many media errors. replaced it with the hot spare and will run a full media scan later.

September 30[edit]

  • yarrow river: copy finished, restarted mysqld on yarrow
  • yarrow river: reformatted /aux0 as UFS, copying old data from clematis:/aux0/yarrow-backup

September 29[edit]

  • yarrow dab: stoped mysql, it's useless. Asked TimStarling for a new dump of s3.

September 27[edit]

  • hemlock dab: Did maintaince and changed discstructur (details: [2]).
  • yarrow dab: Started mysql_safe. mysql seems crashed without message in the logs.

September 26[edit]

September 17[edit]

  • zedler dab: Switched master for s2 to lomaria.

September 15[edit]

  • hemlock dab: Started Tomcat, was stopped

September 14[edit]

  • yarrow river: recreated RAID array as RAID-0 temporarily, to move s1 from vandale

September 11[edit]

  • clematis river: rebooted, missing drive reappeared

September[edit]

  • September 09
    • 18:55 hemlock dab: Deleted old kernel-sources.
    • clematis river: disk 1 failed
    • zedler river: recreated the /aux1 filesystem as ZFS, to identify the failed disk. re-loaded s2 dump and started replication.
  • September 2
    • Evening zedler dab: Mysql-Database total defect. Reinstall needed.

August[edit]

  • August 27
    • 19:39 yarrow dab: Changed db-master to db5, restart replication.
  • August 24
    • 21:17 vandale dab: Manualy added row image.img_sha1 to enwiki (replication stoped because of missing it). Restarted replication.

July[edit]

  • July 26
    • 16:35 hemlock daniel: added yarrow to phpmyadmin's config, so it can be accessed via the web interface
  • July 19
    • 15:40 hemlock daniel: created script /root/grantit that outputs grant statements for all users, ready to be piped into mysql. Usage is /root/grantit <priv> <target> [client-host] [mysql-server], so for example you can do /root/grantit select "toolserver.*" hemlock.ts.wikimedia.org yarrow to grant SELECT on the toolserver db on yarrow to all users logging in from hemlock.
    • 15:30 zedler/yarrow daniel: toolserver db (with wiki and namespace tables) is now available on yarrow. It contains views that delegate to toolserver_priv, which in turn contains federated tables that map to the respective tables on zedler. The user ts_federated on zedler is used for the federated queries. The views are necessary to hide the password of ts_federated from users, which otherwise would be visible through SHOW CREATE TABLE on the federated tables (in MySQL 5.1 this would not be necessary when using a pre-defined connection created via CREATE SERVER).
