Hi Bernhard,
I thought 4 out of seven wouldn't be good because it's not an odd number...
but I guess after I would have brought up the cluster with 4 MONs I could
have removed one of the MONs to reach that (well, or add one)
Think of it like this:
You created 7 mons in ceph. This is like having a parliament with 7 members.
Whenever you want to do something, you need to convince a majority of
parliament to vote yes. A majority would then be 4 members voting yes.
If two members of parliament decide to stay at home instead of turning
up to vote - you still need 4 members to get a majority.
It is _not_ the case that everyone would suddenly agree and acknowledge
that only 5 parliament members have turned up to vote, so that only 3
yes votes would be enough to form a majority.
It doesn't matter at all whether the number of parliament members
showing up to vote is odd or even.
