So this has started your meta-data service. You now need "data" service (i.e. OST(s)). > And “df –h” shows the correct size of my lustre filesystem.

You most certainly do. OSTs are where the data (i.e. the contents of the files in your filesystem) are store. You also need to mount the Lustre filesystem (as a whole) on a client and access it from that client. > Any ideas what I’m doing wrong? How do I access the lustre storage? You create OSTs, mount them, then mount the filesystem on one or more clients and access it from there. It sounds like you really need to take a(nother) read through the operations manual at manual.lustre.org to get a better picture of the overall architecture. b.
