Hi Antonio,
While it's possible that you're getting misleading error messages, the
most likely problem is that you've got new client libraries but an old
server (thus the "Server is too old for your client" message).
Have you (or someone) installed more than one version of PVFS2 on the
system in the past?
Thanks,
Rob

Hi,
I have a problem with the use of btio (NPB vers. 2.4) :

PVFS_util_init_defaults: No such device
as one looks at the problem is that the file "pvfs2tab" are not in "/etc/".
I have tried also :
setenv PVFS2TAB_FILE "/tmp/astrano/pvfs2tab"
but the problem persists !
With mpi-io-test can be used : " -p /tmp/astrano/pvfs2tab", and in BTIO ?
you can help me? Thanks
Antonio
