Hey Scott I have not used a full mesh for Ceph. They have always been switched (physical external) networks. But, if the networking is good, Ceph should not care. Now that you have connectivity on the Ceph networks, does ceph -s give you any output? Or are all your monitors gone?

Thanks for posting your ceph.conf. I think you will have trouble routing fe80::/64. Since I am a fan of IPv6, let's keep it IPv6. Please change your cluster network to something in fd00::/8 (the usable half of fc00::/7). It should be a random prefix, but something like what you are doing...

Hey Scott I do not know of any guide for re-installation. There might be. This might give you what you need to remove Ceph: https://forum.proxmox.com/threads/removing-ceph-completely.62818/ If you are just setting up your cluster, starting fresh is a solid way to go. If you want to try to...

Hi Jens Thanks for posting the last bit of information. So, you are all fixed up now? Or, at least know what is taking up your space on that node?

In your /etc/hosts file, there is an inconsistency. 192.168.102.2 node0.localdomain node2 This should be: 192.168.102.2 node2.localdomain node2 Did you rename your nodes at some point? You will also want to check your /etc/hosts on node0. It should be something like: 192.168.102.X...

Please post the following items: The contents of /etc/pve/storage.cfg The output of find /mnt -maxdepth 3 -type d -ls Where were you looking for /mnt/synology? Were you looking in /etc/fstab, /mnt, or somewhere else?

Were you connecting to your Synology with NFS? I suspect that this is the issue. I have seen cases where a connection to an NFS share is lost, and the data is written locally. If you remove the NFS share and re-add it, you may get a message indicating that you cannot because the directory has...

Sorry, I can see it isn’t NFS. Do you have any NFS storage?

Is your HA-Storage NFS? What is the output of pvesm status?

Please post the output from these commands run on pve1: zpool list zfs list

What are the contents of your /etc/hosts file on node0? From the command line: cat /etc/hosts From the web GUI Datacenter > node0 > System > Hosts

You need to edit the Ceph config /etc/pve/ceph.conf The Ceph Network Configuration Reference will be helpful.

A big part of hardening on any platform is to change default configurations to something more secure. You are right, they both start fairly secure. Install sudo Create and user non-root users Enforce TOTP (TFA) in the GUI on all accounts Ensure TLS certificates for the GUI Harden ssh (guides...

Proxmox does not require specific hardware to get support from them. We are a Proxmox Partner and also do not require specific hardware. Some partners might. Of course, better hardware is usually better :-)

During the installation, you will set up the boot/OS drives. After installation, you will be able to configure the drives. Depending on what you want to do with them, you will do that in the web GUI or command line.

Good catch. Yes, you need to have eno3 and host0 on the bridge. I'm a little out of practice hand-building these. I wrote an Ansible script to build them for my deployments, and now, with SDN, I am moving things back to Linux bridging. # === BRIDGES === auto vmbr0 iface vmbr0 inet manual...

Okay, below is an OVS interfaces file, which should provide an example from which you can build your own. IMPORTANT: You are responsible for reviewing it and confirming it will work for your purposes. I have no way of knowing the configuration of the rest of your setup. A few notes: vmbr0 is...

Please post your Please post your /etc/network/interfaces file before you do the OVS config and after. If you do not have the before version, please post what you have.

Have you installed the openvswitch-switch package?

You need to have quorum ( 50% +1 nodes) to make changes to the PVE file system. You need to bring at least one of the other nodes online.
