    Abstract: The disclosure provides a method for virtual volume (vvol) recovery. The method generally includes determining to initiate recovery of a compromised vvol associated with a virtual machine (VM), transmitting a query requesting a list of snapshots previously captured for the compromised vvol, receiving the list of the snapshots previously captured for the compromised vvol and information about one or more snapshots in the list of snapshots, wherein for each of the snapshots, the information comprises an indication of at least one change between the snapshot and a previous snapshot, determining a recovery point snapshot among snapshots in the list of the snapshots based, at least in part, on the information about the one or more snapshots, creating a clone of the recovery point snapshot to generate a recovered virtual volume, creating a virtual disk from the recovered virtual volume, and attaching the virtual disk to the VM.

    Abstract: A per device state is introduced that indicates whether a storage device is shared clusterwide or not. The state may be populated by default based on detected device locality. Devices detected as local and those shared by only a subset of host machines in a cluster of machines may have the state set to “FALSE.” Devices which are shared by all the machines in a cluster may have the state set to “TRUE.” Locality of storage devices in a cluster may be modified using such state information. Operations upon other storage device state may be modified depending upon device sharing state.

    Abstract translation: 引入每个设备状态，指示存储设备是否在群集范围内共享。 基于检测到的设备位置，默认情况下可以填充状态。 检测为本地设备的设备和仅由机器群集中的主机计算机共享的设备可能将状态设置为“FALSE”。集群中所有机器共享的设备的状态设置为“TRUE”。 可以使用这种状态信息修改集群中存储设备的位置。 可以根据设备共享状态修改其他存储设备状态的操作。

    Abstract: The disclosure provides a method for virtual volume snapshot creation by a storage array. The method generally includes receiving a request to generate a snapshot of a virtual volume associated with a virtual machine, in response to receiving the request, preparing a file system of the storage array to generate the snapshot, wherein preparing the file system comprises creating a delta storage structure to receive write input/output (I/O) requests directed for the virtual volume when generating the snapshot of the virtual volume, deactivating the virtual volume, activating the delta storage structure, generating the snapshot of the virtual volume, and during the generation of the snapshot of the virtual volume: receiving a write I/O directed for the virtual volume and committing the write I/O in the delta storage structure.
