I found this: https://askubuntu.com/questions/1311227/why-does-apparmor-kill-dhclient

I get lots of these messages from dmesg -e: [ +0,019118] audit: type=1400 audit(1699468339.167:19): apparmor="DENIED" operation="create" class="net" info="failed type and protocol match" error=-13 profile="/{,usr/}sbin/dhclient" pid=494 comm="dhclient" family="unix" sock_type="dgram" protocol=0...

I've worked a bit more on this and written two scripts to help me keep two VMs in sync across different hosts. I know, the "official" way to do this is via a cluster, but I like this "handheld" approach more. First, I've written a bash script to help me make snapshots of my VMs (called "ubuntu"...

Thanks to the suggestions from Dunuin I've looked into ZFS replication, and found a way to make it work - although not automatically, yet. I will shortly describe this here, hoping others may be inspired and follow up. I have two Proxmox hosts, A and B. And I have VM 100 running on host A...

Thanks - I will look into ZFS replication, this seems like a good idea.

Thanks - "Incremental restore" would be a nice feature :)

So, I have have Proxmox running with a VM on one node (node A), and twice each day I run PBS to make a backup of this VM. I runs very smoothly and fast, thanks a lot. In case of problems with node A, I have node B ready to take over. I've tried to connect nodes A and B inside a cluster, adding...

Hello I'm feeling foolish, I really believe this should be quite simple. I have 2 Proxmox hosts, connected to the same LAN with a gateway to the world outside. This works fine. Now I want to create a separate LAN to use for the cluster I want to set up. Each hosts has 4 ehternet connections...

Answering part of my own question: I managed to make most things look ok by doing: # systemctl stop pve-cluster # systemctl stop corosync # pmxcfs -l Now the node doesn't complain about missing quorum, and I managed to do backup with PBS with no problems. I also managed to make backups from...

Thanks a lot. I tried this, but now I have in some way messed things up, I think. Now pvecm won't run on the primary node in the cluster. I get this # pvecm status Cluster information ---------------------------- Name: 68B Config Version: 17...

I have a Proxmox installation, humming on nicely on a HPE Microserver with 4 disk bays. Proxmox is installed on a single disk, formatted as ZFS, but this disk is too small, and I also want some redundancy. So now I want to move the entire installation to two, larger disks, with ZFS Raid1 on the...

I have a small cluster with a VM providing services (web, email ..) to the outside world. Now and then this VM needs to be updated, e.g. with a new kernel version, and this may require rebooting the VM, leading to 5-10 minutes of downtime. Is it in some way possible to update the VM without...

I tried to rename: Shutdown the VM zfs rename /rpool/data/vm-102-disk-0 /rpool/data/vm-103-disk-0 I then in the GUI tried to edit the hardware configuration for VM 103. But I wasn't able to change Hard Disk (scsi0). Must I detach the hard disk "local-zfs:vm-102-disk-0" and add new virtual...

Thanks a lot for replying. You're right, there's a mismatch between the VM ID and the disk ID. I will get this fixed, next time I shut down the node. Below is the output you ask for. root@sonja:~# pveversion -v | column proxmox-ve: 7.2-1 (running kernel: 5.15.60-2-pve) libjs-extjs...

I try to replicate a VM from one node to another but get the above message. I've searched the forums, and the solution to this problem seems to be to make sure that the VM volumes aren't marked with "replicate=0". Well, I don't think I have this problem, please take a look here on the...

Thanks again for your support. It is ok for me to shut down node A for a short time. Here's the output of zfs list: root@sonja:~# zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 399G 500G 104K /rpool rpool/ROOT 6.94G 500G...

Hello, thanks for your interest. Only two nodes in the cluster The VM was HA-managed Yes, the config file was present in node B Yes, 103.conf new references the disks of 102. 103 is humming away and serving its users nicely. No one except me as sysadm has noticed any changes The two nodes are...

Thanks for the info regarding RAM for the MicroServer Gen10. I now shifted one of my 16 GB blocks to a new 32 GB. They work perfect together, giving me 48 GB. It's a bit odd to think about that when I bought the server, I knew from previous that I probably would need all the RAM I could get...

I have a small cluster with replication of one VM from one node (A) to another (B). I shut down node A, as I needed to change RAM, but when the node rebooted, the VM (102) on it had disappeared. When I looked into /etc/pve/qemu-server, the file 102.conf was missing. I couldn't make a new file...

I have a Proxmox Backup Server making regular backups of a VM on another machine, and it works fine. But I find it hard to restore just a single file. According to the wiki, it's possible to restore a single file, but I can't find the "File Restore" button in the GUI? I can do it via the...
