We have a storage spaces two way mirror two column setup with ReFs.

Each time the DataIntegrityScan runs we get a warning.
Volume metadata inconsistency was detected and was repaired successfully.
Volume name: D:
Metadata reference: 0x204
Range offset: 0x0
Range length (in bytes): 0x0
Bytes repaired: 0x3000
Status: STATUS_SUCCESS

And each time Windows update requires a reboot the volume is detected as RAW!

If we reboot the server again it is detected as ReFs.

Running Windows Server 2016 Standard.
