ext3 file system resources

Hi, I am looking for detailed books, documents, websites that cover the ext3 file system in a fair bit of detail.
Can anyone recommend to me any material that may be of use.

Many thanks

Cheers,

Thanks for the links.
I want to look at ext2/3 security features but I am having trouble pinning down how ext3 implements security features. I realise that there are filesystem permissions and also ext2 attributes that use certain flags to add security to files. Are these the main methods (permissions and attributes) that are used in filesystem security? Are there any other methods that linux uses to add security to its filesystems?

Cheers,

Does anyone know if extended attributes are implemented the same way in ext3 as in ext2?

Thanks

Yes, the only difference between ext2 and ext3 is the addition of journal.

Just to enhance what nske said, journalling, which is the main difference, helps by reducing the file system recovery time in the event of a system crash as it logs changes to the file system (to different extents depending on the mode selected).
