I'm making (as we speak) a 12TB RAID6 array, using XFS. My first attempt I noticed XFS was making waaay too many inodes. I know in ext3 I can adjust the inode count, like # bytes per inode, etc. Does anyone know how to do the same in XFS? Man xfs is super confusing on inode count manipulation. I have no idea what numbers it wants in its parameters.
Since my fs has mostly large (2-4GB) files, I like to reduce the inode count by 1-3 orders of magnitude from the defaults to give me more usable space.
Thanks!

Oh! I found some SGI docs that say that XFS doesn't pre-allocate inodes? So I guess there is no wasted space?
Then what the heck was df -i reporting to me when it said 644244416 inodes existed? Is XFS passing df some made-up number or is that the hard system max?
My first foray into XFS is proving interesting...
