[Pvfs2-developers] Problem with btio-pvfs2

[Rob Ross]

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
