Doc Text: |
Cause: Keepalived did not properly clean up VIPs if it was force restarted by liveness probe (for example).
Consequence: The VIP may appear on multiple nodes, which can cause problems connecting to services behind the VIP.
Fix: Before starting keepalived, ensure that the configured VIPs are removed.
Result: VIPs no longer show up on multiple nodes at once.
