1.2.3.4:/foo /foo nfs auto,rsize=8192,wsize=8192 0 0 1.2.3.4:/bar /bar nfs auto,rsize=8192,wsize=8192 0 0
(I've added "auto", after reading your reply, but that should be on by default anyhow). I've also attempted with "defaults" in the options field, same results. 1.2.3.4 is SunOS 5.x box.
I'm not sure if this will help, but since SunOS 5.x is on other side, try mounting volumes using NFS ver. 2 by default. Add
MOUNTD_NFS_V2=default
to /etc/sysconfig/nfs
Or add nfsvers=2 as one of the mount options for filesystems mounted off a SunOS server, i.e.
1.2.3.4:/foo /foo nfs auto,rsize=8192,wsize=8192,nfsvers=2 0 0 1.2.3.4:/bar /bar nfs auto,rsize=8192,wsize=8192,nfsvers=2 0 0
