Johnny:

Thanks for the reply!

I've already got this entry in /etc/fstab:

128.2.2.25:/mnt/cisrc  /usr3  nfs  rw,rsize=8192,wsize=8192,hard,intr,user 0 0

and it looks to me as if it should be adequate,... at least it always HAS
been up until the kernel update I got yesterday.

The error occurs during boot when the startup tries to mount all filesystems,
as well as whenever I type: "mount /usr3" or anything else that causes the
sys to try mounting it.

Any other ideas?

Thanks again!

Fred

PS: yes, nfs is running:

# pwd
/etc/rc.d/init.d
# ./nfs status
Shutting down NFS mountd: rpc.mountd (pid 4816) is running...
nfsd (pid 4812 4811 4810 4809 4806 4805 4804 4803) is running...
rpc.rquotad (pid 4799) is running...
#


also, I note that (as shown above) the nfs status command says its
shutting down NFS mountd. I believe this is an error in the nfs script,
which contains:

status)
        [ -x /usr/sbin/rpc.svcgssd ] && /sbin/service rpcsvcgssd status
        echo -n $"Shutting down NFS mountd: "
        status rpc.mountd
        status nfsd
        if [ -n "$RQUOTAD" -a "$RQUOTAD" != "no" ]; then
                status rpc.rquotad
        fi
        ;;

Do you agree? Should a bug be filed on this?
