file locking to work.
On the client, the system call fcntl(,F_SETLK,)
returns ENOLCK (No locks available).
On the ShareSpace, I turned on all sorts of
debugging. (cd /proc/sys/sunrpc; echo 1 > nlm_debug,
Now dmesg (on the ShareSpace) shows this every time
a lock request comes in:
nsm_mon_unmon: rpc failed, status=-13
lockd: cannot monitor 192.168.2.2
(The IP address is that of the client)

isn’t. But I can’t start it, because the ShareSpace
firmware does not contain /usr/sbin/rpc.statd.
(There are only /usr/sbin/rpc.nfsd and /usr/sbin/rpc.mountd.)
I downloaded the source code to the ShareSpace firmware
but didn’t get very far trying to cross-compile statd from the
Is my diagnosis correct, and, if so, would it be possible to
get an upgrade to the firmware that includes statd?
