Hi Strange indeed....
There is a better command to use;
btrfs fi usage /
Do you have the btrfs balance script running as a weekly cron job? /usr/share/btrfsmaintenance/btrfs-balance.sh script
It's present in SLE 12, but not in my openSUSE 13.2...
I manually ran and recovered a couple of GB on my system under 'allocated'.
So, I would try a before and after;
btrfs fi usage / /usr/share/btrfsmaintenance/btrfs-balance.sh btrfs fi usage /
I did as you suggest and appear to have gained ~2%. Minimal, but appreciated.
I failed to memtion that the drive is ssd and about 4 years old although it may be as much as 5 years. I wonder if the ssd drive is aging. I haven't had any indications from smartdrive ???

Hi Not sure for an Intel ssd, but if you use the -a option with smartctl eg; smartctl -a /dev/sda What attributes show lifetime or wear? I have an OCZ Agility 3 which is the same sort of era as your device, it's been running (power on hours) for over 20K hours now and still going strong. -- Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) SUSE Linux Enterprise Desktop 12 GNOME 3.10.1 Kernel 3.12.39-47-default up 1:53, 3 users, load average: 0.46, 0.23, 0.22 CPU AMD A4-5150M APU @ 3.3GHz | GPU Richland Radeon HD 8350G -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
