Bernard,
looking at the instalation with fresh eyes this Monday morning.
I noticed that one of the head nodes Ethernet controllers (nVidia force2
on motherboard) was flaky under SL4.2.
It was always slow to start up and sometimes failed causing, ntp
problems, ccsd to fail, and a very very slow start of NFS.
This may or may not have explained the NFS mount and client node login
issues.
But enough is enough. I've decided to stop messing around with
unsupported version on my first set-up and have switched to FC3 to start
afresh. Should have done this to start with. Sorry if I've wasted
anyones time.
on the SL4.2
I don't believe I *had* to use SL_* rpms. I did as I had on SL3.
I definitly saw the conflicts betweem Twisted and python-twisted. which
resolved by removing Twisted (and the dependecny listed with apitest)

Hi Neil:
To get this far I needed to
- add all sl_release*.rpm and all SL_* rpms to the detected
redhat-4EL-i386.rpmlist
these are, I guess, SL extensions to redhat 4 default rpms.
So you're saying using the default rpmlist you cannot create an image on
SL 4.2? Can you enable debugging for update-rpms:
# export DEBUG_UPDATE_RPMS=y
then try to build it (with the default rpmlist for RHEL4), and post the
error log?
- then, prior to running install-cluster, I manually removed
api-test
and Twisted because of conflicts with python-twisted.
This should not be necessary if you are using b5 as this has been fixed:

d=9368&atid=109368
If this does not work then please let us know.
my (only?) issue now is user passwords
- In the cluster-test user 'oscartst' on server to node and node to
server requires a password. i can't see where this was set. and
empty password didn;t work.
these is a user oscartst in /etc/passwd
- I can't log into the client node directly. what user/passwords are
default for root ?
/home is mounted
If /home is mounted (via the headnode) on the compute nodes, then you
don't need a password as you can get in using SSH authorized keys, so
something must be wrong here.
Is it possible to run cluster test via command line without
the wizard ?
Yes, just run the script /opt/oscar/testing/test_cluster on the command
prompt.
Cheers,
Bernard
