Will result in anything reported in 'dmesg' output?[ 6431.514454] device label 388gb-data devid 1 transid 1086 /dev/sda6 [ 6431.514969] btrfs: disabling disk space caching [ 6431.514977] btrfs: force clearing of disk cachetried the same with kernel versions from http://kernel.ubuntu.com/~kernel-ppa/mainline/: * 3.2.20 * 3.4.0 with version 3.4.0, i could delete one tiny file, but only one. peter mentioned before to run the rm as root. yes, i did that, with all kernel versions, the error was the same all the time.Have you tried to delete the files with "echo > file" ? This will empty the file without requiring a new metadata allocation.thanks for the hint! i did with the original kernel, but now i tried it as root and with the 3.4.0 kernel as well. "no space left on device". is there a special kernel version or a special btrfs tool which allows to remove a file without writing more data?
Have you tried mounting with '-o nodatacow' yet?
