[OpenSIPS-Users] Clusterer and Full Sharing USRLOC sync state/persistence

[Liviu Chircu]

Hi all,

Jock: just like Alexei said, I assume you don't have a "seed" node.  
Make sure one node of your opensips.clusterer table has "seed" in the 
"flags" column.  Regarding offline restart persistence: you may skip the 
"working_mode_preset" parameter and individually set "cluster_mode" [1] 
and "restart_persistency" [2] in order to achieve a restart-persistent 
cluster using an SQL DB, rather than point-to-point sync.

Alexei: that is exactly how we meant it to be used.  With 0 nodes 
online, you have to bootstrap the cluster somehow -- this is the purpose 
of the "seed" node.

Cheers,
