STATUS_VOLMGR_MIRROR_NOT_SUPPORTED
The platform cannot provide the requested mirror layout
STATUS_VOLMGR_MIRROR_NOT_SUPPORTED narrows the capability failure to mirrored volumes. The requested operation needs mirror support, but Volume Manager reports that the current Windows or provider environment does not offer it.
A mirrored volume has multiple plexes, with each plex representing a complete copy of the volume data. That model is different from a spanned or striped volume, where extents cooperate to form one nonredundant data set. Substituting a striped layout therefore does not preserve the same failure tolerance.
Confirm the intended resiliency requirement before changing the request. Dynamic disks are deprecated for most new uses, so on modern systems the right fix may be to choose a supported storage technology rather than attempt to force legacy mirror creation.
What to inspect
- Identify whether the caller explicitly requested a mirror or invoked an operation that only applies to mirrored volumes.
- Check operating-system and provider support for dynamic-disk mirroring on the target configuration.
- For new designs, compare the requirement with Storage Spaces or another supported redundancy mechanism.
