How know if file are loose files after a error

[studyfranco]

Hello,

I get a big error on my BTRFS volume (One big volume on a RAID6 megaraid), and my volume go to read-only.
I start a btrfs scrub to check errors, but I have more space than I think. I wanted to know if I loosed a part of my files.
How can I check that ?

Best regards
