Story points:


Currently, when keepstore is trying to read a block, if one Azure-backed volume encounters a 503 error and all other volumes return 404, keepstore returns 404 to its client. This is a non-retryable error so the client will give up.

The correct behavior is to return a 502 or 503 status in this situation.

Azure error message:

storage: service returned error: StatusCode=503, ErrorCode=ServerBusy, ErrorMessage=The server is busy.
