ReFS block‑level reconstruction

Question

Hi guys

Cold‑tier bit‑rot detected on HDD

Repair failed pulling SSD parity

Advanced‑settings mismatch triggered.

How can we manually force ReFS block‑level reconstruction ?

Thanks

No, ReFS does not provide a supported mechanism to manually force a block-level reconstruction. If integrity streams and Storage Spaces redundancy are enabled, ReFS automatically attempts to repair corrupted blocks by reading a valid copy from the mirror or parity data and writing back a corrected block. If that repair fails, there is no command to override or force the reconstruction process.

At that point, focus on identifying why the repair failed: verify the health of the Storage Spaces virtual disk, ensure all physical disks are online and healthy, and check for configuration mismatches between pool members. Review the System event log for ReFS and Storage Spaces errors.

If the volume is severely damaged, the supported recovery option is to restore from backup or use refsutil salvage to recover readable files to another volume. refsutil salvage is a data recovery tool, not a block reconstruction tool.
