    Multiple brigdes

I connected vmbr0 to bond0 (for management and some VMs), then created vmbr1 connected to bond1. If I test vmbr1 with a static IP address from network, it works fine, but...

    [SOLVED] A smoother Ceph reset experience

    I really like what Proxmox VE has done for creating a cluster. I'd *prefer* that there be a smoother reset experience for removing and re-adding a node to a cluster than going to the command line, but I can live with hand-jamming a one-liner. Caph is *not* like that - and in general I've found...
