Re: redundancy with 2 nodes

Hi,

I think you are right. I was too focused on the following line in docs: "A cluster will run fine with a single monitor; however, a single monitor is a single-point-of-failure." I will try to add another monitor. Hopefully, this will fix my issue.

Anyway, I think that "ceph status" or "ceph health" should report at least something in such state. Its quite weird that everything stops...

Thank you
Jiri

Hi,

I have:
- 2 monitors, one on each node
- 4 OSDs, two on each node

POOMA U here, but I don't think you can reach quorum with one out of two 
monitors, you need a odd number:

http://ceph.com/docs/master/rados/configuration/mon-config-ref/#monitor-quorum

Perhaps try removing one monitor, so you only have one left, then take the 
node without a monitor down.
