moveing from 6 to 8 mons and loosing 4 of them instead of 3 will not
save you.

Nice.. Perhaps if I create a VM in Proxmox01 and Proxmox02, and join this
VM into Cluster Ceph, can I solve to quorum problem?

Your question has already been answered. You need majority to have quorum.

I was thing about it, and perhaps if I deploy a VM in both side, with
Proxmox and add this VM to the CEPH cluster, maybe this can help!

Hi,
Can you resend your schema, because it's impossible to read.
but you need to have to quorum on monitor to have the cluster working.

Objet: [PVE-User] Proxmox CEPH 6 servers failures!
Hi there
I have something like this:
CEPH01 ----|
|----- CEPH04
|
|
CEPH02 ----|-----------------------------------------------------|----
CEPH05
| Optic Fiber
|
CEPH03 ----|
|--- CEPH06
Sometime, when Optic Fiber not work, and just CEPH01, CEPH02 and CEPH03
remains, the entire cluster fail!
I find out the cause!
ceph.conf
[global] auth client required = cephx auth cluster required = cephx auth
service required = cephx cluster network = 10.10.10.0/24 fsid =

10.10.10.140:6789 mon osd allow primary affinity = true
[mon.pve-ceph06]
host = pve-ceph06 mon addr = 10.10.10.150:6789 mon osd allow primary
affinity = true
Any help will be welcome!
