Abstract: A distributed data storage system using erasure coding (EC) provides advantages of EC data storage while retaining high resiliency for EC data storage architectures having fewer data storage nodes than the number of EC data-plus-parity fragments. An illustrative embodiment is a three-node data storage system with EC 4+2. Incoming data is temporarily replicated to ameliorate the effects of certain storage node outages or fatal disk failures, so that read and write operations can continue from/to the storage system. The system is equipped to automatically heal failed EC write attempts in a manner transparent to users and/or applications: when all storage nodes are operational, the distributed data storage system automatically converts the temporarily replicated data to EC storage and reclaims storage space previously used by the temporarily replicated data. Individual hardware failures are healed through migration techniques that reconstruct and re-fragment data blocks according to the governing EC scheme.

Abstract: According to an example, a computer-implemented method comprises initiating a first process for atomically setting the primary bias state with a first node of a primary storage cluster of a multi-site distributed storage system due to a temporary loss of connectivity to a mediator or a temporary mediator failure, releasing an atomic lock for the first process on the first node of the primary storage cluster, sending the first process and an associated first generation indicator to a first node of a secondary storage cluster of the multi-site distributed storage system to handle the first process for setting the primary bias state, and initiating a second process for atomically clearing a primary bias state with the first node or any node of the primary storage cluster based on detecting a connection to the mediator or detecting that the mediator is available.

Abstract: Multi-site distributed storage systems and computer-implemented methods are described for improving a resumption time for processing of input/output (I/O) operations during an automatic unplanned failover (AUFO). A first storage cluster includes a first set of consistency groups (CGs) and a second storage cluster includes a second mirrored set of CGs. A computer-implemented method includes prefetching, with a user space of the second storage cluster, configuration information from a replicated database prior to starting the AUFO workflow, sending the configuration information to a kernel space of the second storage cluster on a per CG level while queuing the AUFO workflow, and determining if any in progress workflows conflict with the AUFO workflow.
