Hi,
I'm running CentOS7 ARM port on Raspberry PI 2 model B.
Base system works fine but I noticed that not all RPM packages are 
available.
For my testing purposes I needed pacemaker and corosync installed on 
RPi, but unfortunately it is still not in repo.
I have built both corosync and pacemaker with tiny changes in spec-files:
%if 0%{?rhel}
- ExclusiveArch: i686 x86_64 s390x
+ ExclusiveArch: i686 x86_64 s390x armv7hl
%endif
May be some repo maintainer could build and push pacemaker/corosync to 
the repo?
