Warning Review limit reachedYou’ve reached a temporary PR review limit under our Fair Usage Limits Policy. Next review available in: 58 minutes Limit details: You’ve used the included review currently available. Your 96 included PR review attempts over the past 7 days set your current allowance at 1 review per hour. You can run this review on demand instead of waiting. On-demand reviews are free until September 18, 2026. After that, they cost $0.25 per reviewed file.
How can I continue?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 reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

根安装路径匹配 header/src/main/java/org/zstack/header/storage/snapshot/reference/VolumeSnapshotReferenceTreeVO_.java, storage/src/main/java/org/zstack/storage/snapshot/reference/* |
将元模型字段重命名为 rootInstallUrl。引用树创建、根卷删除和后端卷查询增加根安装路径匹配条件。 |
清理与容量同步流程 storage/src/main/java/org/zstack/storage/addon/primary/ExternalPrimaryStorage.java, storage/src/main/java/org/zstack/storage/snapshot/reference/VolumeSnapshotReferenceUtils.java |
卷链删除完成后异步同步主存储容量。容量同步失败时记录警告并继续回复删除结果。重初始化根卷时，若卷被其他资源直接引用，则跳过原卷删除。根引用清理会查询相同主存储和根安装路径下的相关引用树。 |
ZBS 引用清理验证 test/src/test/groovy/org/zstack/test/integration/storage/primary/addon/zbs/ZbsPrimaryStorageCase.groovy |
新增测试，验证引用根卷重建不会删除仍被引用的旧根卷或创建回收站记录，并验证后续按叶到根顺序清理快照和引用。 |
Estimated code review effort: 3 (Moderate) | ~25 minutes
Merge Risk: 🔴 Critical · up to e02c3
The change can misidentify an active root volume as deleted and remove storage still required by linked clones, creating a serious data-availability risk. This should be fixed before merge.

兔子捧来引用树，
根路径上标记清楚。
旧卷有引用便留住，
删除之后容量同步，

Keep an old root out of reimage trash while downstream snapshot references still depend on it. Distinguish the reimage old root by rootInstallUrl during reference cleanup. After the last downstream reference disappears, delete the chain once from leaf to root, sync capacity, and remove matching legacy reimage trash.
