Hello,
I have a 4 nodes cluster (named pve-01 to pve-04) each server have 96GiB ram and 16CPU with 4 NICs 1Gb and a dedicated switch.
To give some context pve-01 and pve-02 are installed with the proxmox iso and pve-03 and pve-04 with debian 11 then pve installation.
Why debian 11 : because proxmox iso didn't boot on pve-03/04. 2 NICs are in active+backup and used for UI and corosync and the other 2 NICs are used for VM vlan.
Ping between node on corosync network is ~0.236ms. And all my test are done on the UI of pve-02.
So when pve-04 and pve-05 are powered together, they get out and in (and the Quorate state change every 30 sec to 1min30sec). I can see 50% packet loss if I ping from pve-02 to pve-03 or 04.
If I shutdown or unplug the network cable of one of them, the other "stay in", the packet loss "disapear" and the cluster is healthy and stay healthy until I restart the one shutdown.
When I say getting out and in, it's on the UI the green check or red cross near the name of the node in server view. And when pve-04 or pve-05 are marked out, I can still right click->shell on them.
What's happening ? I followed install pve on debian11 for the installation of pve-03 and 04, did I miss something important ?
Best regards,
Pierre
