STATUS_SPACES_NO_REDUNDANCY

Redundancy has already been exhausted for this data

This status is more serious than a single drive becoming unavailable. The provider reports that no good redundant copy is available for the affected data. Whether the virtual disk remains partially accessible depends on the layout and the location of the lost allocation, but the condition cannot be solved by simply starting another rebuild without a recoverable source.

Protect the remaining evidence

  • Stop nonessential writes and avoid destructive recovery actions until the affected virtual disk and physical members are documented.
  • Check the chosen resiliency setting, available copies, fault-domain placement, and every member's health and operational state.
  • Restore affected data from a verified backup when the layout cannot provide a surviving copy; do not promise that adding a new disk recreates data that no longer exists.
