It's definitely not (just) NetApp, though it may be their NFS -- or
NFS in general; I couldn't say. I can't speak to their NFS
implementation, beyond having generally heard good things about it,
but I've run PostgreSQL on filers for years, and have never seen that
message. Granted, I've only been iSCSI- or fibre-attached (or had the
storage path abstracted away by some form of virtualization), so I
haven't seen every possible use-case.

In general, though, I'd be pretty wary of running postgres on an NFS
mount. I know a lot of people run Oracle that way, but at the
filesystem level, there are some vast differences between the two.

Has anyone ever seen this message on non-NetApp NFS?
