Methods, systems, and computer-readable storage media for receiving, by an auto-pilot platform, one or more log files from an in-memory system, determining, by the auto-pilot platform, occurrence of a first error within the in-memory system based on the one or more logs, wherein the first error is indicated by a first error code within the one or more log files, identifying, by the auto-pilot platform, a first resolution from a resolution repository based on the first error code, the resolution repository including one or more mappings associating error codes to resolutions including associating the first error code with the first resolution, initiating, by the auto-pilot platform, execution of the first resolution, and updating, by the auto-pilot platform, the resolution repository based on execution of the first resolution.

A computer system includes a first baseboard management controller (BMC) and a first host of the first BMC. The first host operates a first storage service at the first host. The first host is a first storage device connected to one or more storage drives. The first storage service managing a first Remote Direct Memory Access (RDMA) controller for accessing user data stored on the one or more storage drives through a storage network. The first BMC receives state information of the one or more storage drives. The first BMC sends notifications to a client of the first BMC, in response to receiving the state information.

A synchronization process for virtual-machine images (and other segmented files) provides for generating a “delta” bitmap indicating which segments (e.g., clusters) of a first virtual-machine image were changed to obtain a second (e.g., updated) virtual-machine image on a source node. The delta bitmap can be applied to the second-virtual-machine image to generate a delta file. The delta file can be sent along with the delta bitmap to a target node that already has a copy of the first virtual-machine image. The transferred delta bitmap and delta file can then be used on the target node to generate a replica of the second virtual-machine image, thereby effecting synchronization. In variations, different bitmaps and delta files can be transferred to optimize the synchronization process.

A method for authorizing I/O (input/output) commands in a storage cluster is provided. The method includes generating a token responsive to an authority initiating an I/O command, wherein the token is specific to assignment of the authority and a storage node of the storage cluster. The method includes verifying the I/O command using the token, wherein the token includes a signature confirming validity of the token and wherein the token is revocable.

A method for targeted repair of a hardware component in a computing device that is part of a cloud computing system includes monitoring a plurality of hardware components in the computing device. At some point, a defective sub-component within the hardware component of the computing device is identified. In addition to the defective sub-component, the hardware component also includes at least one sub-component that is functioning properly and a spare component that can be used in place of the defective sub-component. The method also includes initiating a targeted repair action while the computing device is connected to the cloud computing system. The targeted repair action prevents the defective sub-component from being used by the computing device without preventing sub-components that are functioning properly from being used by the computing device. The targeted repair action causes the spare component to be used in place of the defective sub-component.

Disclosed embodiments relate to perform operations for receiving and integrating a delta file in a vehicle. Operations may include receiving, at an Electronic Control Unit (ECU) in the vehicle, a delta file, the delta file comprising a plurality of deltas corresponding to a software update for software on the ECU and startup code for executing the delta file in the ECU; executing the delta file, based on the startup code, in the ECU; and updating memory addresses in the ECU to correspond to the plurality of deltas from the delta file.
