> If a node in the datacenter crashes while processing an operation, occasionally it can leave the Storage-internal blob tracking metadata in an incomplete state. We expect this to happen occasionally, and so all API’s are designed in such a way that if this incomplete state is observed on a blob, the situation is resolved before the current operation proceeds. However, this incident has exposed a bug specifically with the Rename API, where the incomplete state fails to resolve, leading to this incorrect failure. As a temporary mitigation, if any other operation is performed on this blob – GetBlobProperties, GetBlob, GetFileProperties, SetFileProperties, etc – it should resolve the incomplete state, and rename will no longer hit this issue.
