I'm kind of new to working with NFS shares, but here's what I have.








On a client computer, I run the following:

mount /mnt/storage

It hangs for a very long time, then fails with:

mount.nfs: Input/output error

What's the problem here, how can I tell what's going wrong?

can you add the output of 'showmount -e servername' on the client? – Michael Mittelstadt Jun 16 '11 at 0:31
Just a thought, but the URIs can be successfully resolved to IP addresses? – Dabu Jun 16 '11 at 7:01

I needed simply to run portmapper on each client before trying to mount. Weird. I would assume that the mount.nfs command would know to do that, but it apparently doesn't.
