I'm trying to understand how the different types of blocks work for Unix / Linux file systems.

Where can I find what the difference between a superblock and an uberblock means?

One's more über than the other. – Mehrdad Oct 27 '11 at 17:42
What does that mean? – Kaitlyn Mcmordie Oct 27 '11 at 18:16

I think it was a joke... – Shinrai Oct 27 '11 at 18:23
Nevermind the uberblock. What is a 'superblock'? – Kaitlyn Mcmordie Oct 27 '11 at 19:08

Have you done a Google search on the two terms already? What have you found, and what parts confused you. Asking questions is good, but it is important to do some basic research yourself as well. – Zoredache Oct 27 '11 at 19:49

Uber is just German for Super, and is used in English the same way.

You can read about it here, let me quote it for you:

A superblock is a record of the characteristics of a filesystem, including its size, the block size, the empty and the filled blocks and their respective counts, the size and location of the inode tables, the disk block map and usage information, and the size of the block groups.

Uberblock is the Superblock of the ZFS filesystem, here's a good presentation on ZFS.
