Hi,
is it safe (has it an effect?) to use the 'clear_cache' option in a
'mount -o remount'? I recognize messages in my kernel log regarding
'BTRFS info (device dm-7): The free space cache file (31215079915520)
is invalid. skip it'. I would like to fix it and would do it (in best
case) without reboo

Now i do a btrfs-find-root, but it runs now since 5 day without a result.
How long should i wait? Or is it already to late to hope?
