  1. [SOLVED] Ceph : delta in reported total space

    Hello, We now have a well working Ceph cluster with 5 nodes (PVE5.4, Ceph luminous). OSDs are distributed like this : * host1 : osd.12 : 1750 GB osd.13 : 1750 GB * host2 : osd.0 : 894 GB osd.1 : 1750 GB * host3 : osd.5 : 1750 GB * host4 : osd.4 : 1750 GB osd.5...
  2. [SOLVED] Separate Ceph and corosync networks on running cluster (PVE5)

    Hello, In the past, I made a mistake : using the same 10G network to run proxmox cluster AND Ceph cluster. I know, that's bad practice.

We have setup a dedicated 10Gbps network between all nodes for DRBD replication. It would be great to use it for...
  5. [SOLVED] Firewall auto-add MASQUERADE rule

    Hello, We just activate firewall on a Proxmox 4.4 installation. We observed that proxmox automatically add a masquerade rule : # iptables-save |grep MASQ -A POSTROUTING -o vmbr0 -j MASQUERADE So we need to delete this rule at every reboot or the VMs are seeing connections from the hypervisor...
