根因分析
当尝试删除或修改具有活动租约的 Blob 时，如果未正确提供租约 ID，操作将失败，尤其是当 Blob 具有继承或需要单独租约管理的快照时。
English
When attempting to delete or modify a blob that has an active lease, the operation fails if the lease ID is not provided correctly, especially when the blob has snapshots that inherit or require separate lease management.

-
Retrieve the current lease ID by calling 'Get Blob Properties' and then use that lease ID in the delete request. Example in Azure CLI: 'az storage blob lease break --account-name <storage-account> --container-name <container> --blob-name <blob> --lease-duration -1' then delete with 'az storage blob delete --account-name <storage-account> --container-name <container> --name <blob> --lease-id <lease-id>'.
-
If the blob has snapshots, delete the snapshots first with the same lease ID, then delete the base blob. Use 'az storage blob delete --account-name <storage-account> --container-name <container> --name <blob> --delete-snapshots include --lease-id <lease-id>'.
无效尝试
常见但无效的做法:
-
70% 失败
If the lease is still active, the delete operation fails with a 409 error; the lease must be explicitly released or renewed.
-
90% 失败
The Azure Storage API requires an exact lease ID match; wildcards are not supported.
-
60% 失败
Snapshots may have their own leases or inherit the base blob's lease; deleting them without the correct lease ID can also fail.
