[lustre-devel] Index operations

I am trying to understand how index operation work in Lustre. I have a 2
node setup. One of them is a client and the other node is hosting both MDS
and OSS with ZFS as backend filesystem.
I put printk in osd_oi_probe() and I see that there are 128 object indexes
created for each of the MDT and OST.
Now, when I create a file or directory from the client I want to know how
the object index gets mapped to file FID. How the FID -> dnode mapping
works in conjunction with index object.
Any input appreciated.
