STATUS_VOLMGR_DIFFERENT_SECTOR_SIZE
STATUS_VOLMGR_DIFFERENT_SECTOR_SIZE means that the disks selected for one volume do not present the same sector size to Volume Manager. This is a compatibility constraint for the participating disks, not a filesystem-format warning.
Nominal capacity, vendor model, and even the physical media type are not substitutes for the sector geometry reported through the active storage stack. Virtual disks, RAID controllers, and array presentation can make devices that look similar expose different logical-sector sizes.
What to check
- Query the geometry of every participating disk from the operating system at the time of the operation.
- Verify that the intended volume design supports this set of devices; do not use a cloned layout from one member as proof for another.
- Use a supported storage design or migrate data instead of forcing incompatible sector geometry into a multi-disk volume.
