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 = 
e67534b4-0a66-48db-ad6f-aa0868e962d8 keyring = 
/etc/pve/priv/$cluster.$name.keyring mon allow pool delete = true osd 
journal size = 5120 osd pool default min size = 2 osd pool default size = 3 
public network = 10.10.10.0/24 [osd] keyring = 
/var/lib/ceph/osd/ceph-$id/keyring [mon.pve-ceph01] host = pve-ceph01 mon 
addr = 10.10.10.100:6789 mon osd allow primary affinity = true 
[mon.pve-ceph02] host = pve-ceph02 mon addr = 10.10.10.110:6789 mon osd 
allow primary affinity = true [mon.pve-ceph03] host = pve-ceph03 mon addr = 
10.10.10.120:6789 mon osd allow primary affinity = true [mon.pve-ceph04] 
host = pve-ceph04 mon addr = 10.10.10.130:6789 mon osd allow primary 
affinity = true [mon.pve-ceph05] host = pve-ceph05 mon addr = 
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!
