Dear list, A tried to make a full defragmenting on my $HOME directory (which doesn't contain any snapshots). After some hours of running, it stopped with „No space left on device” error. I checked and it ate about 50 GB of free space. Before: Data, single: total=433.83GiB, used=~380.00GiB After: Data, single: total=433.83GiB, used=~430.00GiB Both times: Metadata, DUP: total=8.00GiB, used=7.08GiB In the "btrfs fi df" man page I didn't find anything that is related to this phenomenon. My questions are: - Is it a bug or some consequence of the defrag process? - Can I reclaim somehow the free space? Command used: shopt -s dotglob for i in *; do echo "$i"; btrfs fi defrag -clzo -r "$i"; done Btrfs and kernel version: Btrfs v3.12+20131125 Linux 3.14.4-1.gbebeb6f-desktop #1 SMP PREEMPT x86_64 Best regards, Ákos -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
