Abstract
Embodiments are directed to determining active membership among a set of storage systems synchronously replicating a dataset. Determining active membership among a set of storage systems synchronously replicating a dataset includes determining that a membership event corresponds to a change in membership to the set of storage systems synchronously replicating the dataset. Determining active membership further includes applying, in dependence upon the membership event, one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset. Determining active membership also includes, for one or more I/O operations directed to the dataset, applying the one or more I/O operations to the dataset synchronously replicated by the new set of storage systems.
