STATUS_VOLMGR_INTERLEAVE_LENGTH_INVALID
The data-distribution unit is invalid for this striped layout
STATUS_VOLMGR_INTERLEAVE_LENGTH_INVALID concerns the layout parameter that controls data interleaving across disks. It is relevant to striped or parity-style volume construction rather than to simple single-extent storage.
VDS distinguishes striped and striped-with-parity volume types, both of which distribute data across multiple disk extents. An invalid interleave length means the layout description cannot be accepted with the requested geometry; the status does not say that any existing disk has failed.
Inspect the management request before changing hardware. Record the interleave value, disk count, sector size, and intended volume type, then compare them with the API or component that produced the layout. A stale or incorrectly serialized layout structure can present the wrong value even when the disks themselves are healthy.
What to inspect
- Capture the exact interleave length supplied to Volume Manager and the volume type being created or changed.
- Compare sector sizes across all participating disks and verify the caller is not reusing layout data from another disk set.
- If custom management software built the request, validate its units and structure version before retrying.
