NFS4 with KERBEROS

I was wondering if any of you have used NFS4 with KERBEROS in a HACMP setup and environment with more than 1 resourcegroup that has NFS mount in them.
I Configures the host keys for an Network File System (NFS) server I get stuck with the nfshostkey
I can only add one at a time per system so when I failover NFS stops working.
