Re: [Linux-cluster] nfs4 kerberos

That's interesting about making the portmapper dependant on the IP, was
this for the same reason I'm seeing just now. I used the method from NFS
cookbook where I pseudo load balancing by distributing my NFS exports
across my nodes. Sadly the RHEL 6 portmapper replacement (rpcbind)
replies on the node IP and not the service IP, and this breaks NFSv3
mounts from RHEL5 clients with iptables stateful firewalls.

I opened a bug on this one and have a call open with RH (via Dell) on

But I too would like a good clean method of doing kerberized NFSv4 on a
RHEL6 cluster. I thought NFSv4 being so central to RHEL6 this would be
easy on a RHEL6 cluster (without using XEN)? Can the cookbook be

Which brings up another point. The RHEL cluster documentation is good,
however it doesn't really help you implement a working cluster too
easily (beyond the apache example), it's a bit reference orientated. I
found myself googling around for examples of different RA types. Is
there a more hands on set of docs around (or book)? It could almost do
with a cookbook for every RA!
