All the steps that you did look ok. However, pvfs2-1.3.2 is fairly old and a lot of performance and stability fixes have gone in to our releases since then. Let's try to figure out why pvfs2 1.5.1 does not build for you and then diagnose performance/stability issues from there.. Can you find out what version of berk db is installed on your cluster? Perhaps our configure checks need to be tweaked on your setup to detect things correctly.. thanks for the reports!
