Hi all, I was wondering what is roughly the rate of metadata to data, ie. how large an MDT would you need for an X size OST? I assume it depends on the average filesize etc. (where lots of little files need more metadata then less big files), but say worst case how much should be allocated? Is it a factor 10, 100, 1000 or even better? Thanks, Eli
