Hi All,
Thanks so much for all the info! It looks like Lustre may be the way
forward, for the foreseeable future at least. I hadn't thought of the
limits on accessing/writing small files but by default I was going to
keep our home dirs mounted as NFS anyway and just let people know the
limitations (saying that I did have it in the back of my mind to copy
the home areas across though!). I'm interested in glusterfs but if noone
else is using it I'm happier going with stuff that there's experience
out there for!
Thanks again!!
Mark
