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?
The Linux pNFS file layout server code is designed to be used by
cluster file systems that use the DLM layer. So far, GFS2 has been
exported by pNFS, but OCFS2 has not. It should (in theory) be
relatively painless to export OCFS2...

Thanks a lot!
best,

Yudong, what are you looking for in your tests?
Another option for the pNFS files layout is spnfs which is good for
basic testing
but it is experimental and not very well supported currently; i.e.
if it breaks
under load you'll probably have to fix it yourself...
You could also consider testing exofs - a loosely clustered,
objects-based
file system that provides scalable performance and is stable enough
for
rather intensive workloads.

Thanks.
