Re: Rebuild the monitor infrastructure

Hi Bryan,

I asked the same question a few months ago:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-February/000221.html

But basically, that is pretty bad; you'll be stuck on your own and
would need to get in contact with Inktank - they might be able to help
rebuild a monitor for you.

Cheers,
Martin
