[Linux-cluster] Linux cluster moved to new subdomain

[Lorenz Pfiffner]

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
Lorenz
