[OpenSIPS-Users] need some help using opensips 3.0 cluster module .

[Liviu Chircu]

The federated clustering actually scales very well horizontally:  as 
your subscriber
base grows, you add more active/backup pairs into the mix, further 
partitioning them.

The tutorial teaches you how to add HA for a platform with 2 locations
and 4 nodes.  If you need to add MySQL persistency, change:

modparam("usrloc", "working_mode_preset", "federation-cachedb-cluster")

... into:

modparam("usrloc", "cluster_mode", "federation-cachedb")
modparam("usrloc", "restart_persistency", "load-from-sql")
modparam("usrloc", "sql_write_mode", "write-back")

PS: please forget about "db_mode".  It is deprecated, 100% replaced by 
"working_mode_preset"
in 2.4+, and cannot possibly add any further value, regardless of your 
usrloc needs.
