strange NFS status message

[Mike]

can't get NFS working on FC5, have tried /etc/exports and
system-config-nfs. When I run /sbin/service nfs status, I get:

Shutting down NFS mountd: rpc.mountd (pid 4612) is running...
nfsd (pid 4609 4608 4607 4606 4605 4604 4603 4600) is running...
rpc.rquotad (pid 4596) is running...

Yup, I've tried stops and starts; SELinux settings make no difference
(and I don't think there's any relationship there). I see nothing
related in /var/log/messages

What am I missing? Where else should I look?
