gurubert replied to the thread Pardon my less-than-intelligent question, but is there a way to install Proxmox on a Ceph cluster?.No no no. You got your math wrong. To achieve the same availability as EC with k=6 and m=2 you need triple replication (three copies) meaning a storage efficiency of 33%. It is rarely necessary to go beyond 4 copies. -

"lower" and "higher" are subjective. Ceph achieves HA using raw capacity. suit yourself. this is not a recommended deployment. You are far better served by just having two SEPERATE VMs each serving all those functions without any ceph at all-... -

The number of OSDs isn't relevant to a pool as long as it is larger then the minimum required by the crush rule. For example, If you have an EC profile of K=8,N=2 rule, you need a minimum of 10 OSDs DISTRIBUTED ACROSS 10 NODES. so 1 OSD per node...

Was sich geändert hat: Vermutlich haben bei der Neuinstallation/dem Update die OVS-Bridges oder Bonds die MTU 9000 von den NICs übernommen (OVS negotiiert die MTU automatisch anhand der...

MMarco83 replied to the thread Proxmox SDN Traffic breakout Interface and routing.Yes correct... I configured my SDN underlay network via ‘Fabrics’ using OSPF, and everything works perfectly. The traffic runs exactly over my dedicated VLAN into my switch fabric. But my problem now is: when I attach a guest VM (with SNAT or...

Ich glaub ich habe die Lösung. Habe gerade mal bei der VM die MTU auf 1500 begrenzt und siehe da, ich komme mit allen Protokollen auf alle PVE/PBS. Bleibt also die Frage, was hat sich vor einem halben Jahr geändert?
