I have a few questions about ovn-northd HA.
Does the lock for active ovn-northd have to be acquired from the leader
If ovn-northd didn't acquire the lock, it becomes standby. Does it keep
trying to acquire the lock, or wait for notification, or monitor the
If it keeps trying, what's the period?
Say the active ovn-northd is down, the connection to sb-db is down,
sb-db releases the lock, so another ovn-northd can acquire it.
Is that correct?
When sb-db is busy, the connection from ovn-northd is dropped. Not sure
from which side it's dropped. And that triggers active ovn-northd switch.
Is that right?
In case that sb-db leader switchs, is that going to cause active
ovn-northd switch as well?
For whatever reason, in case active ovn-northd switches, is the new
active ovn-northd going to continue the work left by the previous leader,
or start all over again?
