1. A method comprising:

  • coupling a plurality of compute nodes to a storage system, the storage system interacting with the compute nodes to embody an object store adapted to service objects stored on one or more disks of the storage system, the object store having an on-disk layout that includes a plurality of volumes of the storage system and an incore layout that includes incore data structures of the compute nodes, wherein each volume is a container of the objects, the on-disk layout cooperating with the incore layout to service the objects;

    assembling the compute nodes and the volumes into a compute group;

    mapping the volumes into each compute node of the compute group, each compute node accessing the objects of the object store via the volumes, the mapping enabling each compute node read-write (RW) access to a specified volume of the compute group mapped into the compute node and read-only (RO) access to remaining volumes of the compute group mapped into the compute node; and

    configuring the storage system as a quasi-shared storage system by relaxing a restriction of private storage of the compute nodes to allow shared storage access of the object store within the compute group.
