Lee,

I have been experimenting with iSER/iSCSI and OCFS as the filesystem for a data-intensive system and so far so good. I recommend you look into these if you are looking to create a cluster filesystem.

Thanks mate. So how about PVFS or I just use NFSv4 in the iscsi target
device? I don't know if there are some performance increase from NFSv3
to NFSv4.

Thanks.
