Hi to all

I've been far from ceph from a couple of years (CephFS was still unstable)

I would like to test it again, some questions for a production cluster for VMs hosting:

1. Is CephFS stable?

Yes.

2. Can I spin up a 3 nodes cluster with mons, MDS and osds on the same machine?

Yes.

3. Hardware suggestions?

Depends on your load. :-)

4. How can I understand the ceph health status output, in details? I've not seen any docs about this

I think it is quite self-explanatory when you know how works Ceph. Don't run Ceph if you don't understand it :) Hell don't plan a Ceph deployment before understanding it either (reading this list can help too, look at the archives).

5. How can I know if cluster is fully synced or if any background operation (scrubbing, replication, ...) Is running?

Looking at the health status output.

6. Is 10G Ethernet mandatory? Currently I only have 4 gigabit nic (2 for public traffic, 2 for cluster traffic)

It is not mandatory, I administer 4 3-node clusters and all have 1gbit NICs.

Cheers
Eneko
