The member count is inconsistent with the requested volume topology

STATUS_VOLMGR_NUMBER_OF_MEMBERS_INVALID rejects the number of volume members described by the request. It is a topology-validation status and does not by itself indicate that any member is missing from the machine.

The meaning of a member depends on the fault-tolerant layout: Microsoft protocol documentation treats a mirrored-volume plex and a RAID-5 column/member differently. The expected count therefore has to be interpreted with the volume and plex type, not as a universal constant.

Compare the declared member count with the actual member array and the intended operation. A request generated from stale topology can still contain valid member IDs individually while its count no longer matches the current plex organization.

What to inspect

Validate the count and member array length together before submitting the layout.
Record the associated plex type because member semantics differ for mirror and parity configurations.
Re-enumerate after regeneration, detach, or import events that can change the topology seen by management software.
