    Problems with cluster (adding nodes and QDevices)

    Hi, As some of you have already noticed in other threads, I have huge problems with the cluster and more precisely with adding a node and qdevice for quorum.

Can I pass Node 1's GPU to any VM's that I build on Node 2 (Mini PC)? I do have Nvidia's Grid license...

    Clustering: Any way to work round "a joining node can't have any guests"?

    The question: I see from the documentation at that "All existing configuration in /etc/pve is overwritten when joining a cluster. In particular, a joining node cannot hold any guests, since guest IDs could otherwise conflict, and the node will inherit...

    login failure and pve data is missing after joining cluster

    Hello. I recently added a node (pve2) to an existing proxmox cluster (pve). These nodes are on very similar hardware and are both running 7.4-16.

    Good Evening, I've got a partially broken cluster and I'm not sure how to fix short of fresh installs on everything. When jumping through the GUI, the cluster looks healthy and fine. However, if I'm on any node and try to jump into a vm on another node (to see stats/summary, console, change...

Therefore I added link0 and link1 with a separated network (dual stack) and on a dedicated NIC port, and link2 and link3 the addresses with has gateway...

    Is it possible to create a high-performance cluster using only two PCs with Ceph? What are the correct configuration steps?

    I have two PCs, each with 16 GB of RAM and 500 GB of SSD storage.
