I have a NFS server running Debian Squeeze. Additionally it’s using the 3.2.x kernel from backports, and the nfs-kernel-server from backports too.
Sometimes NFS breaks, and gives helpful messages like :
mount.nfs: connection timed out
or just:
Stale NFS handle on clients.
While I’m confident that my /etc/exports and other configuration files are correct, it still insists on misbehaving.
Below is a random shell script I seem to have created to fix the NFS server –
#!/bin/bash set -e /etc/init.d/nfs-kernel-server stop /etc/init.d/nfs-common stop /etc/init.d/rpcbind stop rm -Rf /var/lib/nfs mkdir /var/lib/nfs mkdir /var/lib/nfs/v4recovery /var/lib/nfs/rpc_pipefs for f in /var/lib/nfs/etab \ /var/lib/nfs/rmtab \ /var/lib/nfs/xtab; do [ -e $f ] || touch $f done /etc/init.d/rpcbind start sleep 2 /etc/init.d/nfs-common start sleep 2 /etc/init.d/nfs-kernel-server start echo "NFS may now work" exportfs -f
Yes… “NFS may now work” … that sums it up about right.
