    Proxmox Memory Usage

    The Proxmox dashboard says almost 80% of the memory is used. I checked that it adds up the max memory of the virtual machines and containers. That's about 50Gb in total. When I add up the real memory usage (like the 111Mb of my media server), then the total is around 20Gb. I am wondering what...

    ZFS-newbie question about LXC snapshots

    I am afraid I am missing a point in my Proxmox setup. LXC snapshotting is said to be enabled on ZFS. I recently did a setup from scratch, so I decided to use ZFS on all my disks with RAID1. (I have pairs of equally sized disks.) I googled a bit to learn about ZFS, and it is mostly suggested to...

    ZFS: create dataset in pool or not?

    I am new to ZFS, but because I have set up my server with a couple of equal-sized disks, I think it makes sense to create RAID1 sets with them. Obviously, I can do that with LVM, but I want to learn something new. I created a ZFS pool on the command line: zpool create nvme_pool mirror /dev/sdb...

    Need advice: MIDI Software on Proxmox - Kernel Recompilation versus VM Passthrough?

    I'm exploring the integration of MIDI software, specifically GrandOrgue, with my Proxmox setup. My machine is robust (24-core AMD Ryzen 9 3900X, 64GB RAM), and currently handles several VMs and containers smoothly. I'm contemplating two approaches: Direct installation of XFCE and GrandOrgue...

    What do I need to change to enable making snaphots?

    When I try to make a snapshot of an LXC it says: The current guest configuration does not support taking new snapshots. Why is that? hmm.... just had a quick look at my other containers and VMs. All of them have the same issue, except one. As far as I can see the difference is the disk...

    Can I remove local and local-lvm?

    I use the storages nvme and ssd for all my VMs and LXCs. I do not use local and local-lvm. Can I safely remove them? Or otherwise just unselect all contect types, so that I cannot use it for anything?

    NVMe vs SATA SSD (VMs/LXCs vs Data)

    I have NVMe SSDs, and SATA SSDs. As I am planning to reconfigure my server, I was wondering what would be wise.... I will combine the disks into two logical volumes, mounted as /nvme and /ssd, and I want to use one of them for the VMs and LXCs, and the other one for the data folders that are...

    LVM striping: a good idea?

    I have grouped similar disks into LVs. NVMe SSDs together in one LV, the SATA SSD's together the second LV, and a bunch of spinning disk together in one big LV. My main concern about this is (if I understood it correctly): the system first fills up the first physical disk before using the next...

    ZFS newbie question

    From what I have read, I understand that ZFS is a lot faster than EXT4, so I want to give it a try. I do not need RAID redundancy, because it is only a homelab that does not run any critical applications. And in case of troubles, I have Ansible playbooks to set up all my containers and VM's from...

    [SOLVED] Add notes via command line?

    I have Ansible playbooks for creating containers and vms. In the proxmox module I cannot set the Notes that are displayed in the Proxmox GUI. I would like to add some kind of description. Can that be done through the command line, so that I can script it?

    dev-hugepages.mount: Failed to execute /bin/mount: Exec format error

    My proxmox systems does not start up correctly anymore because of this message. What could be the reason of this? And more important: how to fix it..... UPDATE: I compared the /bin/mount files on the system and the ISO. They appear to be equal in size. But the version on the iso works, and...

    Find older templates (Debian 9)

    In my current version (pve 7) I have LXC templates for Debian 10 and Debian 11. I want to have a version where the default-jdk is openjdk 8. That was Debian 9. I assume there was a Debian 9 template in earlier versions of Proxmox. Is it still downloadable somewhere?

    Delete orphaned backups

    When I delete a VM or LXC, then the backup is not deleted along with it. My backup disk is having a lot of backups that do no longer belong to an existing machine. The pruning system doesn't take care of that either. What is the best way of cleaning those old backup files?

    Understanding backup retention correctly?

    I do not have the backup server installed, instead I use the backup option of the DataCenter. When I set: keep-daily=2,keep-weekly=1 then I have the backup of yesterday and the day before, AND it will keep the backup of last sunday. - the backup on Tuesday will keep Monday and Sunday, pruning...

    Refresh /etc/resolv.conf automatically

    Earlier today, I changed the DHCP settings in my router because I have a new local DNS server. I have set the lease time in my router to 10 minutes. I would have expected that this change was propagated through my netwerk, but the proxmox host did not pick it up, apparently. /etc/resolv.cont...

    Proxmox nested inside Proxmox?

    Hi there, I read about nesting a Proxmox installation on a Virtualbox VM. But I am wondering if installing Proxmox on a VM would work on my Proxmox server itself? I am developing shell scripts and playing with Ansible to install and manage my Proxmox box. Each time I want to do a real test, I...
