So, out of curiosity, I did the following 1) btrfs sub create X 2) I unpacked some source (linux kernel) in X 3) btrfs sub create W 4) I unpacked the same source in W (so X and W have the same content but they are independent) 5) btrfs sub snap -r X X_RO 6) btrfs sub snap -r W W_RO 7) btrfs send W_RO | btrfs receive /mnt/btrfs2 8) btrfs send -p W_RO X_RO | btrfs receive /mnt/btrfs2 And this is the exact output of 8) At subvol X_RO At snapshot X_RO ERROR: chown o257-1648413-0 failed: No such file or directory
