So, to the point, I've been getting this on a 2016 server hosting hyper v:
A corruption was discovered in the file system structure on volume
\\?\Volume{1c63d7ca-0000-0000-0000-f01500000000}.
The Master File Table (MFT) contains a corrupted file record.
The file reference number is 0x9000000000009.
The name of the file is "<unable to determine file name>".
I didn't see that volume listed in diskpart, nor in vssadmin list shadows. I also checked for the GUID for the VHDs for the guests, not there. I'm thinking it's a vss but I can't fully determine.
Can anyone point me to finding out what that GUID is for?
