is this a typo or is "mgr" the real dns suffix? Single label DNS name 
are really not recommanded.  Could you please first try to reprovision 
with a standard domain name with a .local, .loc or .lan at the end?

After that, check in your /etc/hosts that the machine name nfs4.mgr.loc 
does not maps to, make it point to your eth0 address, with 
FQDN name first and short name second.

Hope this helps,
