Debian Squeeze (NFS broken with backports kernel)

Our office server has been running the Squeeze-Backports kernel for some time – without issue – until today. Amongst the things it ‘should’ do, is act as an NFS server for the office computers (giving us a common /home directory).

Every so often, NFS breaks for some reason. Perhaps in some way, the NFS server feels a need to keep a hold over me.

Anyway, as a routine update, the server started running a newer kernel ( linux-image-amd64 3.2.0-0.bpo.4-amd64 ) today. From then on, NFS clients were unable to mount and at most would give :

mount.nfs4: Connection timed out

(I even saw this on the server when trying to mount the export there)

On the server, the only error message I could see was :

svc: failed to register lockdv1 RPC service (errno 97).

Upon upgrading the nfs-kernel-server package to¬†1.2.5-4~bpo60+1 –

apt-get install -t squeeze-backports nfs-kernel-server

everything started to work again.
