Hello,
my /home folder is on a single device btrfs partition.
When I ls a directory, I get these messages on ls:
ls: cannot access 'file1' : Input/output error
ls: cannot access 'file2' : Input/output error
ls: cannot access 'file3' : Input/output error
and dmesg says:

I scrubbed the filesystem but no errors were detected/fixed.

How can I fix this corruption? How can I detect if more
files/directories are affected?
Kind Regards,
