but as the size of treenode is 32bytes and one treenode contains 8 or 16
physical chunk id. if one chunk equals one page that has 2kb data,so that
one file can be as large as 2^16 * 2KB=128MB. that's what i mean.
what does chunk_group and tnode_size used for?
i'm confused about tnode_size and chunk_group in the sourcecode.
