STATUS_VOLMGR_EXTENT_NOT_CONTIGUOUS

STATUS_VOLMGR_EXTENT_NOT_CONTIGUOUS applies to a retained volume whose growth rule requires the next extent to be immediately adjacent to the existing one. It is more specific than "not enough space": free capacity may exist elsewhere on the disk, but it cannot be used for this extension.

Do not assume that a volume manager can relocate existing data or create a spanning layout as a side effect. The status describes a constraint of this volume state and requested operation.

What to check

Locate the current end of the volume and the next physical range on the same disk.
Determine which partition, metadata area, or other extent breaks adjacency.
Choose a supported migration or redesign path instead of forcing a noncontiguous range into a retained-volume request.
