Is it expected? I obviously do have enough space and can create (and delete) files and directories but am not able to rename anything. Do I need to open bug report?
As Jeff noted, 10MB is really small and the effects of the safety over-reservation calculations are noticeable. Following the steps
linux-1a7f:~ # btrfs filesystem df /mnt System: total=4.00MiB, used=4.00KiB Data+Metadata: total=5.00MiB, used=60.00KiB
(~5mb of space to operate)

I can rename the files with 3.12-rc5, and I believe this is due to patch "Btrfs: fix worst case calculator for space usage" that should be safe to take to opensuse 13.1, but not at this time of release period. david -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
