More reviews will be available in 30 minutes and 29 seconds. Learn how PR review limits work. Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file). ⌛ How to resolve this issue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits. 🚦 How do rate limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate. For paid Pro and Pro+ PR reviews, CodeRabbit uses rolling per-developer review limits. Reviews become available again as older review attempts age out of the rolling limit window.

Code Review by Qodo
1. Unsafe NHC reuse
|
…etion on creation (PR medik8s#29 review) - Replace iptables -F (flushes all rules) with targeted iptables -D for each injected CephFS rule in both DeferCleanup and AfterAll - Remove rbd from discoverRWXStorageClass provisioner filter; rbd (Ceph block device) is not RWX-capable, only cephfs and nfs qualify - NHC deletion already correctly gated by nhcCreatedByUs (no change needed)
|
Fixed Qodo findings: (1) iptables -D instead of -F, (2) removed rbd from RWX discovery, (3) nhcCreated only true when Create succeeds. |

Verifies only storage-isolated node is fenced; healthy nodes untouched. Fixes: pod name limit 63 (not 253), CephFS-only RWX discovery, nsenter -- separator in injection rules, watchdog.go simplify to strings.Fields, doc comment, constant naming, deterministic node sorting. Polarion: OCP-88877
