    RBD Cache to offset consumer NVME latency for an uptime prioritized cluster (data consistency lower priority)

    Hi everyone, so I have a proxmox cluster with zfs replication on consumer NVMEthat I'm planning to change into Ceph. The cluster host multiple VMs that require high uptime so users can log in and do their work, the user data is on an NFS (also on VM). The data is backup periodically and I am ok...

    /var/tmp/espmounts/7276-6706/EFI/proxmox/6.5.13-6-pve: No space left on device when installing new kernel

    I have a single node install with PVE 8.2.4 and ZFS Mirror as boot drive. I was doing apt update and was suggested to do a apt --fix-broken install. I ran that and got this: root@pve:~# apt --fix-broken install Reading package lists... Done Building dependency tree... Done Reading state...

    Proxmox CPU allocation with P and E cores?

    Hey guys, how does Proxmox handle the P and E cores when allocating? For example, on a 13900K, I will have 8p and 16e => 36threads => 36 vCPU. When creating a VM, I input 8 cores for the VM. How would that behave performance wise? Will it get maximum 8 P cores? Or will it use CPU % like 8/36...

    ZFS mirror various disk size

    Hi Aaron, I'm planning to do the same: 1x2TB NVME 1x4TB NVME Mirroring 100GB from each and leave the rest unpartition so I can use them for other things. For this, based on your instruction, I would have to: 1. Choose the 2TB for ZFS RAID0 during installation 2. Use hdsize = 100GB 3...

    Installing Proxmox Root on LVM-Thin

    Hi, I was wondering if it's possible to install Proxmox and have the root partition be on lvm-thin instead of think lvm like default. Wouldn't that be a better approach since now the root can take as much or as little storage as needed from storage?

    Overprovision CPUs

    Thanks, you're right that currently I'm limited on memory. The setup is a Haswell Xeon 4c8t and 16gb of ddr3. I'm moving to a i5 12400 6c12t and 64gb of ddr4 next week. I honestly don't really need much more cpu power and the xeon is doing just fine with my 2 VMs + 20 or so LXC but ram is...

    Overprovision CPUs

    My host has 4 cores 8 threads. Does it make sense to allocate 8 vCPU to all my LXC and VMs if I know that none of them will ever max out all 8vCPU at the same time? I'm not sure if that will create any scheduling issue or overhead as compares to allocate a smaller number to each of them. I saw a...
