This can happen, if the cluster.conf in the initrd has a lower version number 
than the cluster version number. If this is the case, the active cluster.conf 
with the higher version number will be used.

Yes, you can run this on the booted systems. bootsr is just doing some updates 
to the chroot environment, if not already done.
