I'm an end user trying to use btrfs-convert but when I installed btrfs-tools and its dependency btrfs-progs on kubuntu 18.04, the installation was successful, and it shows that v4.15.1-1build1 was installed.
However, when using the command # brtfs-convert /dev/sda4 (with the drive unmounted) the resulting error appears "command not found" I also tried command "btrfs convert" in case this was folded into the main tool, but this also failed. 1. Is btrfs-convert still available? 2. Where can I find it? 3. Has btrfs-convert been replaced? what is it's new name? 4. Is it safe to use a downgraded version of btrfs-tools ie: 4.14 or older?
