STATUS_VOLMGR_RAID5_NOT_SUPPORTED
Parity-volume support is unavailable in this environment
STATUS_VOLMGR_RAID5_NOT_SUPPORTED is the parity-specific capability error. Volume Manager was asked to create or manipulate a RAID-5 dynamic volume, but the platform reports that this volume type is unsupported.
Windows models RAID-5 as striped storage with parity and treats it as fault tolerant. Its recovery path regenerates parity/data across members, which is distinct from mirror resynchronization. A system that supports dynamic disks in general does not necessarily support every fault-tolerant layout.
Check the target operating system and provider before diagnosing the disks. For a new storage design, also account for Microsoft’s deprecation of dynamic disks for most uses and evaluate a current resiliency mechanism instead of trying to force legacy RAID-5 volume support.
What to inspect
- Confirm the requested volume type is striped with parity rather than a normal striped volume.
- Verify RAID-5 dynamic-volume support for the Windows edition and storage provider in use.
- If the requirement is new parity-protected storage, compare supported Storage Spaces configurations before redesigning around dynamic disks.
