Hi
I solved this problem by backing up the luci db (it's binary stored in Data.fs), 'luci_admin backup', saving the luci_backup.xml, removing luci (rpm -e luci), reinstalling it (yum install luci),
adjust node ip's in luci_backup.xml, copying it back to /var/lib/luci/var/, and restoring it back with 'luci_admin restore'. Of course, luci has to be shutdown during this procedure.
It worked this easy for me because the keys of my nodes didn't change.
I don't know if this is the proper solution, but at least it worked for me and maybe helps other people with the same problem.
Kind regards

Hi Dave
Did you solve this problem? I have a similar case here. I changed the
IP's of one of my two node cluster and now I can't get the cluster back
into luci. I assume luci stores it's config in a binary Zope Data.fs
file. But how can change something there?
BTW: Changing node IP's was pain! A Howto would be an interesting thing
for the Knowledge Base or even RedHat Magazine. I think it would really
be appreciated by many Cluster Suite operators.

Yes, The issue is that when I first built the cluster I used the
full qualified host name. I changed the cluster.conf file,
But some where it is still getting the old fully qualified host name.
I can see it in the log files. Where else does it
Store the cluster host names other then the cluster.conf file ?

Hi Dave,
Did you make the appropriate changes on the iptables, to reflect the
new IPs given to the servers?
Sincerely,

We moved our Linux cluster to a new tcpip subnet.
It is running Redhat V4 update 6. After the move I fixed the
cluster.conf to reflect the subnet name.
I then went into luci. When I select the cluster tab I get an error
message stating "an error occurred when trying to contact any of the
nodes in the ermmro cluster"
The systems show up ok in the homepase tab and everything looks
correct under the storage tab.
