Hi Benny,

Thanks a lot for the reply! I will check exofs.

We are looking for a block-based cluster file system that can be
deployed on top of a cluster of commodity machines and can use the
machines' local storage instead of using a SAN. We find that OCFS2 is
a good candidate. Is it possible to use OCFS2 as the storage server in
pNFS?

Thanks a lot!

best,

Yudong
