Re: Retrying connections, persistence, controller restart for ovsdb southbound

i had a related question, for switch restarts. do we rely on ovs persistence to save the config, or do we always push down the controller's version of the config to the switch?

if former, then do we need a resync mechanism, to handle config changes that occured between switch reboots? the same resync operation could be used during controller restart.

thanks,
daya

So we probably also need to get one for retrying connections.. because currently if the ovsdb node is not available or reachable when we configure a connection, we never retry, and if it goes away temporarily, we never retry.

https://trello.com/c/bOrmGbXQ/46-resync-persisted-config-to-ovsdb-correctly-on-restart-of-controller is a trello card that Eric has taken involving controller restart for OVSDB southbound.  This is just a few of the restart scenarios though, IIRC.
