ToDoList 22.6.2013
edit- who can copy the DBs off WMF server if not DaB?
Data Center Tasks
edit- SAN: connections inbetween all working?
- network switches cannot really fallback in case of a core router going offline - Mark knows and a maintenance window is due
- get 6x 8-10m OM3 fibres to make all SAN connections to oe10 redundant
Databases
edit- linux virtual MySQL instances suffer a bug regarding the slave process - if the connection to the master fails for too long it wont restart and also a stop/start slave will only cause the MySQL process to be inoperable so killing the daemon is the only option but recovery may take hours
OSM
edit- setup strabon to be the database successor of ptolemy
- PHP stinks here - things dont work as expected - switch to Linux + Apache would be nice to have
Load Balancer Resetup
edit- resetup of turnera:
not done:
LDAP NFS - final sync takes 3 hours where NFS needs to be readonly, mount the homes from the SAN volume and resync to the local array after new fs DNS recursor TS mysql Squid
setup damiana like turnera and make failover tests automatic restart of services on turnera
firewalling for the load balancers puppet for the load balancers
