I did falko's guide on howto set ut NFS share with 2 servers.. But when server 1 goes down and 2 takes over the client gets "Permission denied" and the same when server 1 gets up again and takes back the command. And some times i have gotten "mount.nfs: mount to NFS server '192.168.13.100' failed: RPC Error: Program not registered" and i need to restart nfs-kernel-server on the server to get it to work.. Yes i added Reverse dns record for the client's hostname. Anyone know something that can help me fix this?
