After some time, things ground to a halt and I got out of disk space errors. btrfs fi df / showed about 1TB of *data* free, and 500MB of metadata free. Below are the btrfs fi df / and btrfs fi show. I ended up having to reboot the machine. I was not able to get the machine to boot again after that, and ended up having to resort to a rescue environment, at which point I copied everything over to an ext4 filesystem. This is this first time I have tried btrfs since I experienced (unfixable) corruption a year or so back, with 3.7 and up. I was led to believe that the ENOSPC errors had been resolved. Would a more recent kernel than 3.11 have done me any good? turnip:~ # btrfs fi df / Data, single: total=1.80TiB, used=832.22GiB System, DUP: total=8.00MiB, used=204.00KiB System, single: total=4.00MiB, used=0.00 Metadata, DUP: total=5.50GiB, used=5.00GiB Metadata, single: total=8.00MiB, used=0.00 turnip:~ # btrfs fi show Label: none uuid: 9379c138-b309-4556-8835- 0f156b863d29 Total devices 1 FS bytes used 837.22GiB devid 1 size 1.81TiB used 1.81TiB path /dev/sda3 Btrfs v3.12+20131125 -- Jon Software Blacksmith
