Once upon a time, Chris Murphy <lists(a)colorremedies.com> said:
How does the audit system determine space available? If it's
using btrfs configured for raid1 or raid10, df and stat will report the total storage of
all devices in the volume, unlike md raid (or even proprietary raid). Instead df reports
logs files as using twice as much space.
How is _anything_ (programs, users, admins) supposed to know how much
free space is left on btrfs? This behavior seems like an admin's
nightmare.
