NFS no longer mounts: rpc-statd fails to start

Whenever I try to start an NFS mount I get:

I tried to chown /var/lib/nfs to rpc, which just gives me the error minus the "Running as root" line:

I have tried to reinstall nfs-utils:

$ pacman -R nfs-utils
$ rm -r /var/lib/nfs
$ pacman -S nfs-utils 

It then re-creates the directory with the permission of the root user... I'm not even sure if this error even related to rpc.statd not starting...

I also tried to run rpc.statd -F --no-notify in my shell, but that just exits with code 1. No error, no nothing... There's no verbose or debug flag documented in the manpage.

I also tried to empty my /etc/exports, and my system is up to date (pacman -Syu). I didn't change anything, it just stopped working a few hours ago...

Note that using mount -o nolock /data works; so the rest of the NFS/rpc deamons seem to be fine...
