摘要： A controller for a storage system manages distribution of snapshots for one or more replicas of a dataset. In certain embodiments, the controller may perform steps including: determining, within a container system, a set of storage resources, where a volume is replicated on each storage resource of the set of storage resources, and wherein the set of storage resources comprises a first number of storage resources associated with a replication factor for the volume; determining, based on a replication policy and in response to an indication to generate a snapshot of the volume, a subset of storage resources, where the subset of storage resources comprises a second number of storage resources that is less than the replication factor; and generating, in accordance with the replication policy, a snapshot of the volume on each storage resource of the subset of storage resources.

摘要： An illustrative method includes detecting a request to perform a cluster-wide snapshot of a cluster comprising one or more nodes on which one or more containerized applications are deployed, the snapshot corresponding to a point in time; preparing, based on the request, objects within the cluster for the snapshot; and generating, in response to the preparing, the cluster-wide snapshot of the cluster.

摘要： An example method for automated elastic resource management of a container system by a storage system comprises providing, by a container storage management system, a volume for use by a containerized application of a container system, the volume deployed on a node of the container system; analyzing, by the container storage management system, incoming input/output (I/O) operations to the volume; and adjusting, by the container storage management system and based on the analyzing, a capacity of a resource associated with the node.

摘要： An example method for provisioning volumes in a distributed storage system comprises: receiving a volume provision request to allocate data storage space for a storage volume on a storage node cluster comprising a plurality of storage nodes; determining, in response to the volume provision request, locations of replicas of other storage volumes on the plurality of storage nodes; determining, based on the locations of the replicas of the other storage volumes, a placement of replicas of the storage volume on a set of storage nodes of the plurality of storage nodes that minimizes a number of failed storage volumes in an event of a failure of the set of storage nodes; and provisioning, based on the determining the placement, the storage volume on the set of storage nodes.

摘要： A container storage system that provides storage services to a container system provides data resiliency using storage pools based on: detecting an interruption to storage services associated with a first storage pool that includes a first plurality of storage resources on which a first set of replicas of a dataset is distributed; selecting, in response to the interruption, a second storage pool that includes a second plurality of storage resources; and generating, based on one or more replicas within the first set of replicas, a second set of replicas of the dataset distributed among the second plurality of storage resources in the second storage pool.
