    摘要： In a storage system that includes a plurality of storage devices configured into one or more write groups, quorum-aware secret sharing may include: encrypting a device key for each storage device using a master secret; generating a plurality of shares from the master secret such that a minimum number of storage devices required from each write group for a quorum to boot the storage system is not less than a minimum number of shares required to reconstruct the master secret; and storing the encrypted device key and a separate share of the plurality of shares in each storage device.

    摘要： Rehabilitating storage devices in a storage array that includes a plurality of storage devices, including: receiving a request to rehabilitate a storage device that is operating outside of a defined range of expected operating parameters; selecting, from a hierarchy of rehabilitative actions that can be performed on the storage device, a rehabilitative action to perform on a storage device in dependence upon information describing a number of times that one or more of the rehabilitative actions have been performed on the storage device; and initiating execution of the selected rehabilitative action.

    摘要： Managing storage device evacuation that includes a plurality of storage devices, including: detecting, by the storage system, an occurrence of a storage device evacuation event associated with a source storage device within a write group, wherein the write group is a subset of storage devices storing a data set; responsive to detecting the occurrence of the storage device evacuation event, identifying, by the storage system, a target storage device for receiving data stored on the source storage device; and migrating, by the storage system, the data stored on the source storage device to the target storage device.

    摘要： Distributing management responsibilities for a storage system that includes a storage array controller and a plurality of storage devices, including: identifying a plurality of elements in the storage system; for each of the plurality of elements in the storage system, creating a distributed manager, wherein each distributed manager is configured for gathering information describing the state of the associated element in the storage system, determining an action to perform against the associated element in the storage system, and executing an approved action against the associated element in the storage system; and creating a distributed management hierarchy that includes each of the distributed managers.

    摘要： Performing a tune-up procedure on a storage device including determining, during a boot process, that a first storage device is available for a tune-up procedure, wherein the tune-up procedure prepares the first storage device for use after being offline; reserving the first storage device to perform the tune-up procedure, wherein reserving the first storage device prevents another system from performing the tune-up procedure on the first storage device; and executing the tune-up procedure on the first storage device.
