Just in case there is any problem and I can't do things myself

• DONE change apache configuration files on ippc01-ippc10

At 8pm

• DONE (scripts are finished): check if jt scripts are still running on ippc19: make them asleep
• DONE make sure ippdb02 is synchronized with ippdb00, stop slave on ippb02
• DONE apache is connected to ippdb02 (check process table) restart apache servers on ippc01-ippc10
• N/A wake up jt scripts: if crashed, tell jt
• DONE kill nebdiskd on ippdb00
• RUNNING start nebulous mysqldump on ippdb00 (use pbzip2)

2012-05-29 19:00 The dump is running in screen session named nebulous_dump (i.e. reconnect on ippdb00 with screen -r nebulous_dump). The dump file is /export/ippdb00.0/nebulous_dumps/nebulous-20120529_fulldump.sql.bz2 and should have a size of 26G (according to the last successful dump of ippdb02 started this morning)

2012-05-29 19:50 The dump should be finished around 0:30 (6 GB in 54 minutes / 27 GB for the complete dump).

Once neb dump is finished

• copy reference dump to ippdb02 (and from ippdb02 to ipp001)
• delete nebulous database on ippdb00
• stop the mysql server
• clean mysql on ippdb00 (remove old binlogs, move and compress mysql logs)
• start the mysql server
• ingest neb dump on ippdb00
• write down new master coordinates
• move and compress nebdiskd log
• restart nebdiskd

Once ingestion is finished

• restore apache configuration files on ippc01-ippc10 (backup files are called /etc/apache2/modules.d/apache2-mod_perl-startup.pl.20120529_ippdb00)
• restart apache servers (jt scripts should be finished?!)
• restart ipp
• delete neb dump on ippdb00

Once everything seems fine, * on ippb02 *

• comment neb dump in root crontab
• delete nebulous database
• stop the mysql server
• clean mysql (remove old binlogs, move and compress mysql logs)
• start the mysql server
• ingest neb dump
• set master coordinates
• start slave
• activate neb dump in root crontab
• delete neb dump
