pacemaker-1.1.rng was renamed to pacemaker-next.rng in Pacemaker 1.1.12,
as it was used to hold experimental new features rather than as the
actual next version of the schema. So, the schema skipped to 1.2.

I'm going to guess you were using the experimental 1.1 schema as the
"validate-with" at the top of /var/lib/pacemaker/cib/cib.xml. Try
changing the validate-with to pacemaker-next or pacemaker-1.2 and see if
you get better results. Don't edit the file directly though; use the
cibadmin command so it signs the end result properly.

After changing the validate-with, run:

  crm_verify -x /var/lib/pacemaker/cib/cib.xml

and fix any errors that show up.
