Hi,
One simple BQ cluster setup via
active - passive HA model.
Per Se...
One BQ active box and one passive BQ standby box.
the shared data will be on Distributed Replicated Block Device, DRBD and Linux heartbeat
eg: box A partition Sync to box B partition
/replicated/etc/mail
/replicated/var/mail
/replicated/var/spool/mqueue
/replicated/var/spool/mqueue-client
/replicated/var/spool/mail
So When active is down, passive box force stop
all services. And restart all services.
Since CCE is transactional, any incomplete transaction
will automatically rollback.
And fcsk on /home/sites
Cheers
patrick
