Reconciliation in sync replication

A distributed storage system replicates data for a primary logical storage object on a primary node of the storage system to a secondary logical storage object on a secondary node on the distributed storage system. Failures in writing data to the primary logical storage object or failures in the replication of the data to the secondary logical storage object can cause data that should be synchronized to become divergent. In cases where the data may be divergent, reconciliation operations can be performed to resynchronize the data.

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.

HOT UPDATES TO CONTROLLER SOFTWARE USING TOOL CHAIN
20210255850 · 2021-08-19 · ·

Disclosed embodiments relate to performing updates to Electronic Control Unit (ECU) software while an ECU of a vehicle is operating. Operations may include receiving, at the vehicle while the ECU of the vehicle is operating, a software update file for the ECU software; writing, while the ECU is operating, the software update file into a first memory location in a memory of the ECU while simultaneously executing a code segment of existing code in a second memory location in the memory of the ECU; and updating a plurality of memory addresses associated with the memory of the ECU based on the software update file and without interrupting the execution of the code segment currently being executed in the second memory location in the memory of the ECU.

Automated self-healing database system and method for implementing the same

An automated self-healing database system is provided that includes a primary database, an application server that writes data to the primary database and reads data from the primary database when it is available, a standby database that is a replica of the primary database, and a self-healing module (SHM). The SHM can automatically detect unavailability of the primary database, and if the standby database is available, the SHM can automatically enable the standby database as readable and writable, assign the standby database the role of primary database at the primary site to start replicating data to other standby databases, and use a pre-established connection between the application server and the standby database to allow the application server to read data from the standby database and to write data to the standby database resulting in the standby database assuming role of the primary database at the primary site.

Method and device for rebuilding raid

Embodiments of the present disclosure provide a method and device for RAID rebuilding. In some embodiments, there is provided a computer-implemented method. The method comprises: determining a spare redundant array of independent disks (RAID) group with spare capacity from a plurality of disks included in at least one RAID group of a storage pool; building spare logic units from the spare RAID group; and in response to a RAID group of the at least one RAID group of the storage pool being in a degradation state, rebuilding a failed disk in a degraded RAID group using the spare logic units.

Control device, control method, computer program product, and communication system

According to one embodiment, a control device includes one or more processors. The one or more processors receive a message. The one or more processors determine whether the received message has been replicated and transmitted. The one or more processors instruct recording of difference information between a message before replication and the received message when it is determined that the received message has been replicated and transmitted.

Information processing with failure detection, apparatus and method

An information processing device is provided with: a first processing unit that generates first information by performing first processing with respect to sensor information acquired from a sensor; a second processing unit that generates second information by performing, with respect to the first information, second processing that is different from the first processing; and a third processing unit, which generates third information by performing, with respect to the first information, third processing, i.e., processing that corresponds to at least a part of the second processing, and which acquires the second information, and outputs the second information and the third information.

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.

Shared filesystem for distributed data storage system
11079942 · 2021-08-03 · ·

A method for controlling access to a shared filesystem stored in a distributed data storage system is provided. The method can include storing a file comprising a shared filesystem as an inode object and a series of data block objects comprising the shared filesystem. Responding to a request from a client to open the file can include generating, in the shared filesystem, a client object, an open file object, and a client index object. The client object can be linked to the open file object and the client index object. The open file object and the client index object can be further linked to the inode object to indicate the file being accessed by the client. Related systems and articles of manufacture, including computer program products, are also provided.

Self-healing learning system for one or more controllers
