According to this Red Hat bug report (which I am trying to reproduce) it looks like the Netapp filer is able to store data directly in the inode, in case of very small files.

Considering I had a FS with large inodes, would it be possible to store data in such a way on a Unix / Linux file system?

ext4 since kernel 3.8 supports this: it can store (very) small files within the inode, as described in the filesystem layout documentation.

Other filesystems support this on Linux too, or variants of the idea; for example Btrfs stores small files in the parent extent.

    Thanks. I will now have to find out out to create such files, though it will probably be the matter of a different question. – Manu Apr 21 '15 at 10:32
