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.
