This last command is wrong - snapshot name is missing. If you mean btrfs subvolume snapshot <mountpoint-for-btrfs-root> xyz - I get "File exists" (assuming that all previous commands were with <mountpoint-for-ntrfs-root> as current directory. This is on openSUSE Tumbleweed with kernel 4.6.4-2 and btrfsprogs 4.6.1-1. If my assumption is wrong, please copy and paste exact commands used to reproduce it. > 4.btrfs subvolumme show xyz > output > ..... > Snapshot(s) > xyz > xyz > ..... > picture from my console reproducing this.
