Setting pool size to 1 is dangerous. Add an option like yes_i_really_really_mean_it, similar to what we have for pool deletion, when pool size needs to be set to 1.

ceph osd pool set mypool size 1 --yes-i-really-really-mean-it

Pool deletion also requires a config option to be set on the monitor before it's allowed through.
I think we should do that for pool size 1 as well, and not make it easy for users to find that option?

I assume you are talking about:

To remove a pool the mon_allow_pool_delete flag must be set to true in the Monitor's configuration. Otherwise they will refuse to remove a pool.

Is that correct?
