STATUS_VOLMGR_FAULT_TOLERANT_NOT_SUPPORTED
The requested layout needs fault-tolerant volume support
STATUS_VOLMGR_FAULT_TOLERANT_NOT_SUPPORTED is a capability error. Volume Manager was asked to create or manipulate a fault-tolerant dynamic layout, but the current operating-system or provider configuration does not expose that class of volume.
Windows distinguishes non-fault-tolerant simple, spanned, and striped dynamic volumes from mirrored and RAID-5 layouts. The latter keep redundant data or parity and therefore require support that a basic disk, unsupported edition, cluster scenario, or provider may not supply.
Do not troubleshoot this as a failed member unless another status reports a degraded existing volume. First identify the requested volume type and the management API or tool that chose it, then verify the platform supports that layout on the selected disks.
What to inspect
- Confirm whether the request is for a mirror, parity volume, or another operation that assumes redundant plexes or members.
- Check the disk type and provider because basic disks are not fault tolerant in the VDS storage model.
- If this is new deployment design, prefer a currently supported resiliency technology rather than forcing deprecated dynamic-disk features.
