  1. [SOLVED] IPv6 Neighbor Solicitation not forwarded to VM

    Hi, I have a weird problem here. Sometimes the IPv6 connectivity of VMs is broken. In this case the Router send ICMP Neighbor Solicitations to the VM, but doesn't get a response back, so the neigbor entry for these VMs are in failed or incomplete state on the router. After capturing a bit it...
  2. PVE/CEPH Cluster Verhalten

    Hallo, wir haben ein 3-Node CEPH/PVE Cluster (PVE 6.4-5/ CEPH 15.2.11) und haben ein paar Ausfalltests durchgeführt. Dabei ist uns aufgefallen, dass CEPH quasi gar nicht mehr reagiert, wenn die Links vom CEPH Public und CEPH Cluster Netzwerk down sind. Also auch die (pve-)ceph. Befehle geben...
  3. Hostname/IP in hosts Einfluss auf "Server Address"?

    Hallo zusammen, uns ist aufgefallen, dass auf unserem 3-node Ceph-PVE-Cluster (PVE 6.4) auf jedem Knoten teils unterschiedliche Server Addresses verwendet werden: Server View -> Datacenter -> Summary -> Nodes. Unsere Nodes haben natürlich mehrere IPs (GUI, Corosync, Ceph Public, Ceph Storage...

  6. [SOLVED] SAN Multipath/LVM // systemd-udev-settle hangs

    Hi, I'm struggling with multipath and lvm configuration. I know it is not directly related to PBS, but on this there runs PBS 1.0.11 (Enterprise subscription). I want to use a SAN LUN (Multipath with 2 links) as a physical volume, to run LVM on that and use it as a Datastore for PBS. Server...
  7. [SOLVED] PBS questions

    Hello, I'm new to PBS, we have installed a PBS instance to backup our 3-node Proxmox/CEPH Cluster. We have configured a user on PBS for the VE integration with permission "DatastorePowerUser" on the exact datastore for the VE Cluster. Is this sufficient as least privilege? How does the...
  8. [SOLVED] CEPH separate public/cluster network

    Hi, we have set up a 3-node Proxmox VE/CEPH Cluster with one network/VLAN/IP-range for both public and cluster network. Now we decided to separate public and cluster network into 2 VLANs/IP ranges. 1. Is there a way to do this in an easy way? (we don't have workload, yet - so service...
