I get these errors on my mysql hosts:
ERROR: lsb:nfs-common: could not parse meta-data:
ERROR: lsb:nfs-common: no such resource agent
ERROR: lsb:nfs-kernel-server: could not parse meta-data:
ERROR: lsb:nfs-kernel-server: no such resource agent

I could install the nfs software on the mysql servers and mysql on the nfs
server. 
But it does not seem like an elegant solution.
