I've seen the above errors several times before. The symptoms that
seem to be present when it occurs is the lack of a valid dns entry for
the entry in /var/spool/pbs/server_name, which is pbs_oscar by default
(for example, type 'host pbs_oscar' and getting a host not
found).
Often times (but not 100%), I've been able to correct this by changing the
entry in /var/spool/pbs/server_name to match the dns entry for the head
node. If the nodes can resolve the IP for the head node, you're in luck.
I've always (100% of the time) been able to correct this by writing my own
DNS authority zones for the cluster, and resolving all of the
oscar-specific hosts in /etc/hosts manually through bind (eg. pbs_oscar*).
Afterwards, rerun the "complete cluster setup" and the test-cluster should
pull through without a complete reinstall.
I'd provide some easy zone examples here if you're interested, but
hopefully someone will interject here about why this isn't the "Right
Thing to Do(tm)".
Anecdotal observations: Most of the time I've seen this issue when the
cluster is being installed without an external network connection or when
there is no DNS entry on the local LAN's dns for the IP of the head node.
I'd appreciate it if anyone could chime in here with steps that I could
take so that this step isn't necessary.

(*) Keep in mind though, that underscores are not valid characters for
hostnames (ref: RFC 952 and 1123), so that alternate DNS servers
(pdnsd, for example, which is more light weight and secure than bind)
will refuse to honor these hosts.
