> h3. Root cause
> Same as HDDS-16589, in the follower read variant of the test. The test stops
> the current leader OM and immediately sends a write. The client gives up
> after 5 failovers while the remaining OMs are still electing a new leader,
> failing with "Could not determine or connect to OM Leader". The test also
> reads the current proxy node ID before the first request, so it may not point
> at the leader yet.
> h3. Fix
> Apply the HDDS-16589 change to
> TestOzoneManagerHAFollowerReadWithStoppedNodes: read the proxy node ID after
> the first createVolumeTest and call waitForLeaderToBeReady() after stopping
> the OM.
