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!
