Create a new volumeset in a GVC with explicit performance class, filesystem type, initial capacity, snapshot policy, and (optional) autoscaling. Performance class and filesystem type are IMMUTABLE — choose carefully. xfs/ext4 support snapshots; shared is read-write-many but cannot be snapshotted. Snapshot defaults injected when omitted: createFinalSnapshot=true, retentionDuration "7d". customEncryption (customer-managed KMS keys) cannot be set here — apply a full manifest with the CLI (`cpln apply`), calling get_resource_schema (kind=volumeset) first. Mount separately via mount_volumeset_to_workload (ext4/xfs need a stateful or vm workload; shared mounts on any workload type). Recommended reading before first use: get_cpln_skill("stateful-storage") — the runbook for this tool family (read once per session).
