I am hoping someone can point me in the right direction on how to setup up different networks for the different traffic, including "public" and "cluster". I am new to linux / proxmox, so detailed instructions are appreciated.
As of now all 5 servers are running the latest PROXMOX and they are...
Hi guys,
I am trying to change Ceph networks. Since now I had one subnet (172.16.254.0/24) both for public and cluster network. The goal is to have this configuration:

Hello,
I've got a 4 node PVE cluster with 3 of those nodes sharing a ceph pool. I'm running Ceph Quincy 17.2.7. I did an upgrade from Proxmox 7.4 to 8.1 and followed the steps on the 7 to 8 guide including updating to the correct repos for both PVE and Ceph. While the PVE upgrade seems to have...

Hello,
I would like to set up a Proxmox cluster at OVH. 3 Hosts with CEPH for HA.
I was thinking of using the Advance 3 offer from OVH. I've mapped out a solution in my lab with 3 machines,
each with a 1TB SSD. After configuring a 1TB CEPH datastore including the SSD for each host.

I was trying to install Ceph on a new 3-node Proxmox cluster. Therefore, I created two extra network bridges for my two 10G ports. The installation of Ceph was successful. However, when I wanted to configure the public and cluster networks, I encountered the following error:
Multiple IPs for...
Hello, I'm managing a cluster of 4 nodes using proxmox 7.4-17 with CEPH. After a messy shutdown caused by a long power outage, a couple of VM images were corrupted, but we could restore them from backup. However, two of the OSD services refuse to come back, showing this kind of error:

Proxmox noob here - I've been asked to setup a 3 node PVE 8.1.10 cluster specifically to investigate options for monitoring with our NMS.
First install, I hit the (apparently) well known CEPH v18.2 (Reef) dashboard compatibility problem, and subsequently rebuilt the cluster and installed CEPH...
We'd been having issues with a particular (Synology) Hyper Backup quite some time.
Synology support analyzed the log files and told us that there's no ETag returned after a multi-part upload:

Hi,
Long shot.... Trying to repair the questionable decision to reinstall for upgrade from 7.4.x and to 8.1.4.
Question: Why is the iperf3 showing these issues? Not necessarily even a problem, but still very strange results.
