[ovs-dev] [PATCH 1/2] ovn-ctl: Support NB and SB DBs to start without

aginwala amginwal at gmail.com
Fri Jun 8 19:32:22 UTC 2018


using remote connections from DB tables.

e.g --remote=db:OVN_Southbound,SB_Global,connections and
    --remote=db:OVN_Northbound,NB_Global,connections

can be skipped for cases where slaves do not need to listen on nb and sb db
connection tables while using pacemaker with load balancer for ovndb clusters.
