This will show you in where both tools create their snapshots, and it will show (parent_uuid field) which subvolume they're taken from. While all of the snapshots with a matching parent_uuid are snapshots of the same thing in linear time for btrfs, the tools may have their own added administration on top (like snapshot names, or directories they're placed in), which prevents them from being able to do something with the other ones. This is not the fault of btrfs, it's because those tools probably are designed to ignore anything they didn't cause to happen themselves. -- Hans van Kranenburg -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
