英文:
Reduce kubernetes Persistent Volumes
问题
I am using multiple apps on Kubernetes and all are configured with pd-ssd volumes. Some deployments are running on large volumes with less data. So I want to reduce the volume of the pods. I have worked on increasing the volume size, and it worked. But I can't reduce the volume space.
Steps I followed:
Current size is 100Gi, and I want to resize it to 30Gi.
- Scaling down the application and pods.
- Editing the PVC to reduce the size of the volume using the following command:
k edit pvc my-pvc
However, I encountered the following error when trying to save the changes:
error: persistentvolumeclaims "my-pvc" is invalid
A copy of your changes has been stored to "/tmp/kubectl-edit-4ivk1.yaml"
error: Edit canceled, no valid changes were saved.
I'm unable to save the changes to reduce the volume size.

在Kubernetes中，不支持缩小持久卷的大小，您只能增加它。
使用Kubernetes调整持久卷大小
英文:
Shrinking persistent volumes is not supported in kubernetes, you can only increase it.
