How it works
+-----------------------------------------------------------------------------------+------------------------------+
| Description | Expected Result |
+-----------------------------------------------------------------------------------+------------------------------+
| Step 1 — Create MS cluster (realm/zonegroup/zone required), create user | Success |
| with quota and configure credentials and endpoint (HTTP or HTTPS) | |
| Step 2 — Upload a control object (no realm reload yet) | 200 OK — no crash |
| Step 3 — Shorten quota cache TTL to 15 s (runtime, no restart) | Success |
| Step 4 — Perform a realm reload (radosgw-admin period update --commit) | Success |
| Step 5 — Wait for cache TTL to expire, then send two PUT requests | |
| Buggy build → 1st PUT ok, 2nd PUT crashes the daemon | SIGSEGV / connection refused |
| Fixed build → both PUTs succeed | 200 OK |
| Step 6 — Verify daemon health via HTTP/HTTPS HEAD request (MS) | Daemon running or crashed |
| Step 7 — Clean up test objects and bucket | Success |
