| 21 | +Announcing the graduation to General Availability (GA) of the PersistentVolume `lastTransitionTime` status |
| 22 | +field, in Kubernetes v1.31! |
| 23 | +
|
| 24 | +The Kubernetes SIG Storage team is excited to announce that the "PersistentVolumeLastPhaseTransitionTime" feature, introduced |
| 25 | +as an alpha in Kubernetes v1.28, has now reached GA status and is officially part of the Kubernetes v1.31 release. This enhancement |
| 26 | +helps Kubernetes users understand when a [PersistentVolume](/docs/concepts/storage/persistent-volumes/) transitions between |
| 27 | +different phases, allowing for more efficient and informed resource management. |
| 28 | +--> |
| 29 | +现在宣布 PersistentVolume 的 `lastTransitionTime` 状态字段在 Kubernetes v1.31 |
| 30 | +版本进阶至正式发布（GA）！ |
| 31 | + |
| 32 | +Kubernetes SIG Storage 团队很高兴地宣布，"PersistentVolumeLastPhaseTransitionTime" |
| 33 | +特性自 Kubernetes v1.28 作为 Alpha 版本引入以来，现已进阶至正式发布（GA），并正式成为 |
| 34 | +Kubernetes v1.31 版本的一部分。该功能帮助 Kubernetes 用户增强对 |
| 35 | +[PersistentVolume](/zh-cn/docs/concepts/storage/persistent-volumes/) |
| 36 | +在不同阶段之间转换的理解，从而实现更高效和更明智的资源管理。 |
| 37 | + |
| 38 | +<!-- |
| 39 | +For a v1.31 cluster, you can now assume that every PersistentVolume object has a |
| 40 | +`.status.lastTransitionTime` field, that holds a timestamp of |
| 41 | +when the volume last transitioned its phase. This change is not immediate; the new field will be populated whenever a PersistentVolume |
| 42 | +is updated and first transitions between phases (`Pending`, `Bound`, or `Released`) after upgrading to Kubernetes v1.31. |
| 43 | +--> |
| 44 | +在 v1.31 集群中，你可以默认每个 PersistentVolume 对象都包含 |
| 45 | +`.status.lastTransitionTime` 字段，该字段记录存储卷最近一次发生阶段转换时的时间戳。 |
| 46 | +该更改不会立刻生效，而是在升级到 Kubernetes v1.31 后，当 PersistentVolume |
| 47 | +发生更新并首次在（`Pending`、`Bound` 或 `Released`）这几个阶段之间进行转换时， |
| 48 | +才会填充该字段。 |
| 49 | + |
| 50 | +<!-- |
| 51 | +## What changed? |
| 52 | +
|
| 53 | +The API strategy for updating PersistentVolume objects has been modified to populate the `.status.lastTransitionTime` field with the |
| 54 | +current timestamp whenever a PersistentVolume transitions phases. Users are allowed to set this field manually if needed, but it will |
| 55 | +be overwritten when the PersistentVolume transitions phases again. |
| 56 | +--> |
| 57 | +## 有什么变化？ {#what-changed} |
| 58 | + |
| 59 | +更新 PersistentVolume 对象的 API 策略已经被修改， |
| 60 | +当存储卷转换阶段时会自动填充当前时间戳到 `.status.lastTransitionTime` 字段。 |
| 61 | +如果需要，用户可以手动设置该字段，但当 PersistentVolume |
| 62 | +再次转换阶段时，该字段会被新时间戳覆盖。 |
| 63 | + |
