Hi,
More on my issue, I have "uncorrectable errors"
# btrfs scrub status /
scrub status for e11013b3-b244-4d1a-a9c7-3956db1a699c
scrub started at Thu Apr 23 19:07:45 2015 and finished after 372 seconds
total bytes scrubbed: 167.13GiB with 13 errors
error details: read=13
corrected errors: 0, uncorrectable errors: 13, unverified errors: 0
Before going to my backups, how can know the files impacted by those
uncorrectable errors?
Best regards,
--Martin
