Howdy, I have a little script that creates hourly/daily/weekly snapshots on a device that otherwise has plenty of disk space free: gandalfthegreat:~# df -h | grep cryptroot /dev/mapper/cryptroot 232G 144G 85G 63% / /dev/mapper/cryptroot 232G 144G 85G 63% /usr /dev/mapper/cryptroot 232G 144G 85G 63% /var /dev/mapper/cryptroot 232G 144G 85G 63% /home /dev/mapper/cryptroot 232G 144G 85G 63% /tmp /dev/mapper/cryptroot 232G 144G 85G 63% /mnt/btrfs_pool1 I have kernel 3.3.1. The FAQ of course talks about the topic: https://btrfs.wiki.kernel.org/articles/f/a/q/FAQ_1fe9.html but I can't get the filesystem show command to output anything useful: gandalfthegreat:~# btrfs filesystem show /dev/mapper/cryptroot Btrfs Btrfs v0.19 gandalfthegreat:~# and the btrfs df ssems to show that I'm ok: gandalfthegreat:~# btrfs filesystem df /home Data: total=169.01GB, used=134.70GB System, DUP: total=8.00MB, used=28.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=5.88GB, used=4.39GB Metadata: total=8.00MB, used=0.00 gandalfthegreat:~# I read about rebalance but it's a mostly new fliesystem will little churn, and I'm not anywhere close to full filesystem yet. So far, when this happened, I've had to delete a set of older snapshots. This would make sense if I was close to full, but at 63% I'm nowhere that. Any idea what's going on and how I can debug further and more specifically what I should capture next time I get a no free space error in userspace?
