Hi, 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. Thanks, -Sudhe
