1. At least one non-transitory computer readable medium encoded with instructions which, when executed, cause at least one processor to perform operations comprising:
taking a snapshot of a file system virtual machine (FSVM) of a virtualized file server (VFS), the VFS including a plurality of FSVMs, including the FSVM, the FSVM hosted on a first computing node of a computing node cluster, wherein the plurality of FSVMs are configured to present a namespace of storage items, the namespace implemented using a storage pool distributed across the computing node cluster, the storage pool including local storage devices of computing nodes of the computing node cluster;
utilizing the snapshot to create a clone of the FSVM (cloned FSVM), the cloned FSVM hosted on a second computing node of the computing node cluster;
updating metadata for shared access to a storage item by the FSVM and the cloned FSVM; and
receiving a storage access operation for access to the storage item by at least one of the FSVM or the cloned FSVM.
