由于未删除PV的ONTAP 卷、PVC挂起
适用场景
适用于 Kubernetes /OpenShift 的 Trident
问题描述
在创建Kubernetes或Trident Snapshot之后、要用于另一个Pod的Kubernetes PVC克隆
、终止原始Pod并删除其PVC不会完全清除Trident中的PV信息。
、终止原始Pod并删除其PVC不会完全清除Trident中的PV信息。
由于克隆繁忙的Snapshot至少显示两个错误、删除操作失败：
type: 'Warning' reason: 'VolumeFailedDelete' persistentvolume pvc-UUID is still attached to node WORKER_NODEAPI status: failed, Reason: Failed to delete volume \"trident_PREFIX_pvc_UUID\" in Vserver \"VSERVER\"because it has one or more clones.\n\nUse the \"volume clone show -parent-vserver VSERVER -parent-volume trident_PREFIX_pvc_UUID\" command to list clones, and either delete or split the clones and retry the operation.\n\nUse \"volume clone split start -vserver \u003cvserver name\u003e -flexclone \u003cclone name\u003e\" to split clones.\nUse \"volume delete -vserver \u003cvserver name\u003e -volume \u003cclone name\u003e\" to delete clones., Code 15894","level":"error","message":"Unable to delete volume from backend."
此外、PVC在输出"oc|kubectl get pvc -o wide"中显示为已释放。
