Volume Provisioning in a Distributed Storage System

A system comprising:

• one or more memories storing computer-executable instructions;
• and
• one or more processors to execute the computer-executable instructions to:
• receive a volume provision request to allocate data storage space for a storage volume on a storage node cluster comprising a plurality of storage nodes;
• determine, in response to the volume provision request, locations of replicas of other storage volumes on the plurality of storage nodes;
• determine, 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
• provision, based on the determining the placement, the storage volume on the set of storage nodes.

A non-transitory, computer-readable medium storing computer instructions that, when executed, direct one or more processors of one or more computing devices to:

• receive a volume provision request to allocate data storage space for a storage volume on a storage node cluster comprising a plurality of storage nodes;
• determine, in response to the volume provision request, locations of replicas of other storage volumes on the plurality of storage nodes;
• determine, 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
• provision, based on the determining the placement, the storage volume on the set of storage nodes.
