Sorry I forgot to mention this in the just sent email. When I tried to build
pvfs2 1.5.1, all the steps went through until I reached the step of creating
the storage space:
# /opt/pvfs2/sbin/pvfs2-server /etc/pvfs2-fs.conf
/etc/pvfs2-server.conf-<frontend> -f
PVFS2......starting
[E....] (null): Berkeley DB library configured to support only DB_PRIVATE
environments
[E....] dbpf_getdb_env(//pvfs2-storage-space/....../):Invalid argument
thanks

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!
