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?
2. Can I spin up a 3 nodes cluster with mons, MDS and osds on the same machine?
3. Hardware suggestions?
4. How can I understand the ceph health status output, in details? I've not seen any docs about this
5. How can I know if cluster is fully synced or if any background operation (scrubbing, replication, ...) Is running?
6. Is 10G Ethernet mandatory? Currently I only have 4 gigabit nic (2 for public traffic, 2 for cluster traffic)
