can anyone please tell where i could find a decent documentation for ext3 inode?
where all the fields in the inode are explained in detail.
Thanks in advance.

Since you asked broad questions before, could I ask you what you've actually searched for and what you found?

i have searched on google. and have come across many sites like wikipedia etc.. Also gone through source code.But all of these explain very little.
Want a more detailed document sorts.

So basically you're giving me a non-answer. Completely understandable if you never came across the concept of reciprosity. Point is
by giving back nothing specific, nothing tangible, we don't know what you found and what it lacked in "detail". Therefore you make it hard for us to help you. So I'll just send you off to read Dave Poirier's The Second Extended File System. If that's not enough look for "Understanding the Linux Kernel" (ULK) version 3.

have started reading the ulk.
but the link which u gave ceases to open. does it have an alternate page? basically i want to have maximum documentation/information about the inode as i am working on filesystems and inode/superblock being the backbone of filesystems, i need to understand these structures very well.

You can get a lot of information using dumpe2fs. Install the kernel source and read the header definition for the ext3_inode structure.
