** Description changed: If I create a snapshot, of a subvolume and try to use btrfs send it fails with "No such file or directory" # sudo btrfs sub create /testvol Create subvolume '//testvol' # sudo btrfs - btrfs btrfsck btrfs-debug-tree btrfs-image btrfs-select-super btrfstune - btrfs-calc-size btrfs-convert btrfs-find-root btrfs-map-logical btrfs-show-super btrfs-zero-log + btrfs btrfsck btrfs-debug-tree btrfs-image btrfs-select-super btrfstune + btrfs-calc-size btrfs-convert btrfs-find-root btrfs-map-logical btrfs-show-super btrfs-zero-log # sudo btrfs sub list / ID 257 gen 16298 top level 5 path @ ID 276 gen 16298 top level 257 path testvol # sudo btrfs sub snap -r /t - testvol/ tmp/ + testvol/ tmp/ # sudo btrfs sub snap -r /testvol/ /test-snap Create a readonly snapshot of '/testvol/' in '//test-snap' # sudo btrfs sub list / ID 257 gen 16299 top level 5 path @ ID 276 gen 16299 top level 257 path testvol ID 277 gen 16299 top level 257 path test-snap # sudo btrfs send /test-snap/ > /dev/null At subvol /test-snap/ ERROR: open @/test-snap failed. No such file or directory This error has been reported upstream: https://bugzilla.kernel.org/show_bug.cgi?id=69401 Because ubuntu creates /home and / on subvolumes this currently prevents backup solutions based on btrfs send.
