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.
