    Abstract: Embodiments maintain high availability of software application instances in a fault domain. Subordinate hosts are monitored by a master host. The subordinate hosts publish heartbeats via a network and datastores. Based at least in part on the published heartbeats, the master host determines the status of each subordinate host, distinguishing between subordinate hosts that are entirely inoperative and subordinate hosts that are operative but partitioned (e.g., unreachable via the network). The master host may restart software application instances, such as virtual machines, that are executed by inoperative subordinate hosts or that cease executing on partitioned subordinate hosts.

    Abstract: Techniques are disclosed for maintaining high availability (HA) for virtual machines (VMs) running on host systems of a host cluster, where each host system executes a HA module in a plurality of HA modules and a storage module in a plurality of storage modules, where the host cluster aggregates, via the plurality of storage modules, locally-attached storage resources of the host systems to provide an object store, where persistent data for the VMs is stored as per-VM storage objects across the locally-attached storage resources comprising the object store, and where a failure causes the plurality of storage modules to observe a network partition in the host cluster that the plurality of HA modules do not. In one embodiment, a host system in the host cluster executing a first HA module invokes an API exposed by the plurality of storage modules for persisting metadata for a VM to the object store. If the API is not processed successfully, the host system: (1) identifies a subset of second HA modules in the plurality of HA modules; (2) issues an accessibility query for the VM to the subset of second HA modules in parallel, the accessibility query being configured to determine whether the VM is accessible to the respective host systems of the subset of second HA modules; and (3) if at least one second HA module in the subset indicates that the VM is accessible to its respective host system, transmits a command to the at least one second HA module to invoke the API on its respective host system.

    Abstract: The present disclosure is related to methods, systems, and machine-readable media for workflows for series of snapshots. A server can manage replication of a number of series of snapshots of a virtual computing instance (VCI). An on-host agent can replicate a parent series of the number of series of snapshots to at least one child series of the number of series of snapshots. The parent series can precede the at least one child series in the number of series of snapshots. A change in the parent series can be propagated to the child series. Management of the replication of the numbers of series of snapshots can be switched from the server to a different server.

    Abstract: The present disclosure is related to methods, systems, and machine-readable media for modifying an instance catalog to perform operation. A storage system can include a plurality of packfiles that store data. The storage system can include a plurality of streams that include a plurality of hashes that identify the plurality of packfiles. The storage system can include an instance catalog that includes an identification of the plurality of streams. The storage system can include an operation engine to perform a number of operations on the plurality of packfiles by modifying the instance catalog using the identification of the plurality of streams.
