hmm... more study needed. I do not understand the difference between VMs and LXCs. A file system is a file system, regardless of the files that are on it, is my simple thinking. But that's my lack of knowlegde in this area...

SATA ports aren't a problem. With your information I think have made my plan. I'll use two small 2.5" disk in a ZFS RAID1 config, for the Proxmox base system. And I am going to buy a PCI NVMe expansion card (with 4 M2 slots) and a bunch of 1TB disks. When I add 4x 1Tb, then I have 6 of them in...

Okay, thanks. I also had another idea, but I don't know if it makes any sense: why shouldn't I take a smaller hdd as boot drive for the OS. I still have some old 2.5" laptop disks lying around. Then I can use the fast ssd's entirely for the VM disk images and containers. Or am I talking nonsense...

I just created a VM with a single disk and installed Proxmox on it, using ZFS RAID0. Works great. I just wanted to check if it works, and it is my very first attempt to use ZFS. I've read that ZFS is still a good thing, even if you use it on a single disk. However,I might still decide to...

Okay.... I based my information about performance mainly on this video. Are those benchmarks not true? But anyway, I am always trying to learn technologies that are new to me, so I think I am indeed going to backup everything and reinstall Proxmox with ZFS. You recommend not to use RAID0, but...

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...

Great! Exactly what I need. Thx.

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?

I have been thinking about it... I think it is a non-issue. The idea of containers is that they only contain an application. The data should stored somewhere else. Often, the installation of an application does not take a lot of time. So, what is the problem of recreating the container in the...

All green: TASK [proxmox_roles/lxc : create container] ****************************************************** ok: [pve] TASK [proxmox_roles/lxc : read vmid] ************************************************************* ok: [pve] TASK [proxmox_roles/lxc : make sure container is started]...

Hi all, I have a nice LXC role in Ansible to create new containers: - name: include password include_vars: file: vars/proxmox_root_password.yml - name: create container proxmox: vmid: "{{ lxc_vmid }}" node: "{{ inventory_hostname }}" api_user: root@pam api_password...

This worked. The grub boot works again.

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...

I switched my server off because I moved it to another room. After reboot it says: error: disk 'lvmid/<very long name>' not found. grub rescue> I checked in the bios, and it looks like all my disks are still available. I have two nvme disks of 1Gb in a volume, and two hhd's together in a...

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?

hmm... I was hoping to find a way (or a shell script) to select backup files that do not belong to an existing machine. In my retention scheme, backups will be removed when they are older than 1 week. So I will add a cron job to clean up files having -mtime +7. Then I do not need to do anything...

I think I can use this cron job for deleting orphan backup files. I noticed that the pruning feature does not clean up backup files of VM's that do not exist anymore.

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?

That prune simulator is great !!

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...
