Public bug reported: 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 # 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/ # 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. ** Affects: btrfs-tools (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1348430 Title: btrfs send does not work for snapshots in subvolumes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/btrfs-tools/+bug/1348430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
