Public bug reported:
In /etc/ceph/ceph.conf, if I set hostnames in the mon_host variable and
separate them with spaces, the parsing algorithm breaks down. The
expectation is that all three of these cases should work. Once
hostnames are introduced in the mon_host line, spaces are no longer
allowed anywhere or parse errors happen.
Precise is being used, here is the ceph-common package information:
