• ovsdb-server-election-timer | int

  Default: 4

  Raft leader election timeout in seconds. The charm allows a value between 1 and 60 seconds. . The Open vSwitch ovsdb-server default of 1 second may not be sufficient for a loaded cluster where the database server may be too busy serving requests to respond to elections in time. . Using a higher value will increase the time to discover a real failure, but you must weigh that against the risk of spurious leader flapping and the unwanted churn that entails. . NOTE: The ovsdb-server refuses to increase this timer to more than 2x its current value in one step. The charm will compensate for this and decrease / increase the timer in increments, but care should be taken to not increase the value too much in one operation. A large increase may take a long time to complete, as the charm will wait an election window between changes.

• ovsdb-server-inactivity-probe | int

  Default: 60

  Maximum number of seconds of idle time on connection to client before sending an inactivity probe message.

  The Open vSwitch ovsdb-server default of 5 seconds may not be sufficient depending on type and load of the CMS you want to connect to OVN.
