Announcing the graduation to General Availability (GA) of the PersistentVolume `lastTransitionTime` status
|
||
field, in Kubernetes v1.31!
|
||
|
||
The Kubernetes SIG Storage team is excited to announce that the "PersistentVolumeLastPhaseTransitionTime" feature, introduced
|
||
as an alpha in Kubernetes v1.28, has now reached GA status and is officially part of the Kubernetes v1.31 release. This enhancement
|
||
helps Kubernetes users understand when a [PersistentVolume](/docs/concepts/storage/persistent-volumes/) transitions between
|
||
different phases, allowing for more efficient and informed resource management.
|
||
-->
|
||
现在宣布 PersistentVolume 的 `lastTransitionTime` 状态字段在 Kubernetes v1.31
|
||
版本进阶至正式发布（GA）！
|
||
|
||
Kubernetes SIG Storage 团队很高兴地宣布，"PersistentVolumeLastPhaseTransitionTime"
|
||
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
|
||
Kubernetes v1.31 版本的一部分。该功能帮助 Kubernetes 用户增强对
|
||
[PersistentVolume](/zh-cn/docs/concepts/storage/persistent-volumes/)
|
||
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。
|
||
|
||
<!--
|
||
For a v1.31 cluster, you can now assume that every PersistentVolume object has a
|
||
`.status.lastTransitionTime` field, that holds a timestamp of
|
||
when the volume last transitioned its phase. This change is not immediate; the new field will be populated whenever a PersistentVolume
|
||
is updated and first transitions between phases (`Pending`, `Bound`, or `Released`) after upgrading to Kubernetes v1.31.
|
||
-->
|
||
在 v1.31 集群中，你可以默认每个 PersistentVolume 对象都包含
|
||
`.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。
|
||
该更改不会立刻生效，而是在升级到 Kubernetes v1.31 后，当 PersistentVolume
|
||
发生更新并首次在（`Pending`、`Bound` 或 `Released`）这几个阶段之间进行转换时，
|
||
才会填充该字段。
|
||
|
||
<!--
|
||
## What changed?
|
||
|
||
The API strategy for updating PersistentVolume objects has been modified to populate the `.status.lastTransitionTime` field with the
|
||
current timestamp whenever a PersistentVolume transitions phases. Users are allowed to set this field manually if needed, but it will
|
||
be overwritten when the PersistentVolume transitions phases again.
|
||
-->
|
||
## 有什么变化？ {#what-changed}
|
||
|
||
更新 PersistentVolume 对象的 API 策略已经被修改，
|
||
当存储卷转换阶段时会自动填充当前时间戳到 `.status.lastTransitionTime` 字段。
|
||
如果需要，用户可以手动设置该字段，但当 PersistentVolume
|
||
再次转换阶段时，该字段会被新时间戳覆盖。

||
