[DRBD-user] rpc.lockd / rpc.statd on heartbeat takeover of drbd systems.

Please forgive the rambling disconnected nature of this message, I have spent
too many hours attempting to answer my own question. I yield, surely someone
on this list has figured out the answer to the question, but not got it in big
bold letters in the howto yet.
should I worry about getting lockd and or statd going correctly?
or should I just make sure the system is configured never to run statd?
what *all* does the script 'nfsserver' called out in the howto do? where can I
get a copy? It is not on my system, not described in the howto and not
apparent with a google search. Does/should it do anything with rpc.statd?
I have been running on the assumption that it is some other distribution's
version of fedora's /etc/rc.d/init.d/nfs script, and it seems to work in the
limited testing I have done.
on Fedora Core release 1,
/etc/rc.d/init.d/nfs --- manages rpc.nfsd, rpc.mountd & exportfs,
/etc/rc.d/init.d/nfslock --- manages rpc.lockd and rpc.statd
if I should worry about it, then should nfslock come before or after nfs in
the haresources line?
"Re: NFS SERVER TAKEOVER"  offers an incomplete analysis/recommendations.
"RE: [NFS] Clustered NFS?"  looks like the drbd HOWTO gets many of the
preconditions ragnark mentions taken care of.
looks like starting rpc.statd with -n SHARED_NAME may be the way to go.
perhaps it should be the fully qualified DNS SHARED_NAME though.
and somewhere in this reading I found that putting
'STATD_HOSTNAME=SHARED_NAME' in /etc/sysconfig/network should do the same
thing...after reading nfslock it looks like Fedora implements this.
Horms indicates that starting rpc.statd the 'number of reboots' gets
incremented causing "the clients do what you want them to do - esabish new
file handles with the other nfs server."
Is this what we really want them to do? I thought we wanted the clients to
think nothing happened, though I am probably making the mistake of looking at
clients as the people at the keyboard.
