VDS_E_PLEX_MISSING
A missing plex is different from a plex that is present but failed. VDS represents plexes as distinct objects with GUIDs and extent topology; if the expected plex is missing, an operation that targets that object cannot proceed normally. The containing fault-tolerant volume may still remain online if another plex is available, which is why volume availability alone does not disprove this error.
Why this state matters
Requery the volume and enumerate current plex objects. Compare their GUIDs and extents with the topology recorded before the failure. Then inspect the disks that contributed to the missing plex for device removal, missing dynamic-disk membership, or I/O failure. Do not create a replacement topology until the operator has decided whether the missing disk may return with newer data.
Diagnostic focus
- Enumerate current plex GUIDs and compare them with the expected topology.
- Map the absent plex to its former disk extents and member disks.
- Check whether a disk is missing, offline, or no longer present in the pack.
- Preserve data-generation context before forcing recovery from a surviving plex.
