It's sort of involved to edit the cluster configuration (CIB)
offline. All nodes need to be shutdown, then remove all cib.*
files on all nodes but one, and on that node you can then edit
the CIB file like this (with crm for instance):

# CIB_file=/var/lib/*/cib/cib.xml crm configure
...

Then you have to remove the corresponding signature file
(cib.xml.sig), because after edit it's not going to match
anymore. Perhaps there's a way to generate it by hand, but I
don't know how. At any rate, pacemaker loads cib.xml in case
the .sig file is not present.

Thanks,

Dejan
