- Add TestFailoverScale class with 8 parametric variations - Use ThreadPoolExecutor for parallel connection/verification - Add MAX_FAILOVER_TIME check (60s limit) - Set 15-minute timeout for test (ZVOL overhead) - Update docstring to document both test suites
- Add TestFailback crash->orderly failback cycle tests (4 tests) - Change TestFailover fixtures to class scope to fix backend switching - Add restore_original_master fixture to restore HA state after tests - Add MAX_FAILOVER_TIME checks for both failover and failback operations
- Add flush before crash failover to reach stable storage - Increase namespace verification retries from 5 to 60 - Handles namespaces initializing gradually after crash
- Fix flush method: send_flush() -> flush_namespace() - Add read retry loop for namespaces not ready after failover - Increase teardown sleep from 5s to 15s for cleanup - Add fixture lifecycle logging to diagnose teardown issues - Verify service state and port release after stop
