I thought most *nix filesystems were like how you describe ZFS (and ext2/3/4) where all the metadata is at the beginning of the disk. At least with the ext family, doesn't the metadata reference the first 10 blocks of a file (where the last two blocks are pointers to double linked lists and the last a reference to a triple linked list). ... It's been a long time since I took that filesystems class, but I recall it's something like that?

That's about right. But with ext2/3/4 there are no snapshots and when you have a reference to a block you know that's the only reference, so it's not a problem there. https://en.wikipedia.org/wiki/Inode_pointer_structure https://en.wikipedia.org/wiki/Inode_pointer_structure has a summary https://docs.microsoft.com/en-us/archive/blogs/askcore/the-four-stages-of-ntfs-file-growth https://docs.microsoft.com/en-us/archive/blogs/askcore/the-f... talks about the NTFS equivalent
