The checkDNS script which is run inside the ceph-mon pods has had
a bug for a while now. If a value of "up" is passed in, it adds
brackets around it, but then doesn't check for the brackets when
checking for a value of "up". This causes a value of "{up}" to be
written into the ceph.conf for the mon_host line and that causes
the mon_host to not be able to respond to ceph/rbd commands. Its
normally not a problem if DNS is working, but if DNS stops working
this can happen.
This patch changes the comparison to look for "{up}" instead of
"up" in three different files, which should fix the problem.
