I try to understand how to build a tree of snapshots (i.e. - which subvolume was used to snapshot/clone other subvolume). What is the correct way to determine it? In particular, "btrfs sub list -p" always prints something for "parent snapshot", while btrfs sub list -q" only prints parent_uuid for actual snapshots (i.e. for subvolumes I know are snapshots). Are "parent" and "parent_uuid" related to each other? Of not, what do they mean? -- 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
