@oguz I've never done this kind of thing before and searching online doesn't tell me much. Which commands would you suggest I run? This is the disk in Proxmox: As you can see, Proxmox uses ZFS. The disk is formatted as ext4 in the VM. And this is the output on the VM: root@roompot:~# df -h...

Unfortunately the backups are still failing every day and I have no clue. What should be the next step @oguz ? In the meantime I have provided an alternative backup.

Hi @oguz, I ran the smartctl command on both NVMe drives I have, but no issues were found. Then I updated both the host and the VM (apt update && apt upgrade) and rebooted both, but still no luck. The backup process still fails at 50% and the error is the same. Below is the output of smartcrl...

I understand there is no webhook support, but what about getting some structured data out (like json or xml) about the backup that was just run. What commands could be useful for exporting the backup information?

Starting today, backup up a VM fails on our Proxmox host. I have no idea why and see no clear cause. The disk is not full and the VM is very small. It has worked every time before. This is a single server (no cluster) and the backup of the small VM is saved locally. The filesystem is ZFS...

@sg90 unfortunately I have no idea about any extra load on the server. It seams like a long shot, as this server is hardly doing anything at this time. It's not fully in use yet (due to lack of time on my part). I also don't have a monitor attached, but will try to find one. Is there no way to...

Hi @wolfgang . Is there anything else I can do?

I know there has been a few threads on running a script after a backup, but I want to ask 1 specific thing. Can we trigger a webhook and send it the details of the backup in a JSON or XML format? Is there structured data available somewhere we can easily HTTP POST or do we need to code the...

Hi Wolfgang, thanks for your reply. Here is the info you requested. Adding it as attachment because the forum won't let me post long messages.

output is: root@proxmox:~# pveversion -v proxmox-ve: 6.1-2 (running kernel: 5.3.10-1-pve) pve-manager: 6.1-3 (running version: 6.1-3/37248ce6) pve-kernel-5.3: 6.0-12 pve-kernel-helper: 6.0-12 pve-kernel-5.0: 6.0-11 pve-kernel-4.15: 5.4-6 pve-kernel-5.3.10-1-pve: 5.3.10-1...

Hello Wolfgang. Thanks for your reply. I have an rpool, but not using swap. The command "swapon -s" returns nothing. How can we investigate further?

I have a single machine running the latest Proxmox (recently updated it too), but it freezes completely about 1x per month. The machine is a very simple setup (no cluster) and runs our office software. Some limited downtime is not a big problem. This machine has: - ZFS - 6 WD Red drives - Intel...

Could I mount the file as a filesystem and then delete stuff?

I have a VM backup that I want to restore, a .vma.lzo file. This file is huge because of an out-of-control process. Can I delete a dir from inside a .vma file and then restore the VM? Restoring the entire VM with all the unneeded data inside would take up way too much time.

Does the Proxmox GUI control "zed"? I mean, are we supposed to set this up manually if we want ZFS warning emails? Would be nice to have this arranged automatically for us, no?

I'm sorry, the VM has an "additional IP" that we got from the datacenter. This IP cannot be kept / moved to the new machine because the IPs are linked to the rack. The new server will be in a different rack. In other words, the publicly facing IP that the VM uses will change. The hypervisors...

We currently have a single machine Proxmox setup with 1 VM inside. The hardware is getting old and needs to be replaced. Typically, we would: 1) Prepare the new machine 2) Stop the VM on the old machine 3) Backup the VM 4) Transfer the VM 5) Start the VM on the new machine 6) Change all the IPs...

Well it's an open question so I don't really know. You make a valid point that I hadn't considered! Maybe I should mount a network share for some data by installing samba on the host...

Is it possible to create a VM on underlying ZFS storage, and not have the VM format it's disk as ext4 but instead use the zvol directly? Thus avoiding a filesystem on filesystem situation... Just wondering if this kind of thing makes sense and is possible so ZFS can be put to optimal use.

Hehe, I don't mind Proxmox being larger scale oriented. I was just surprised by the newer partitioning and didn't account for issues like this. With the older versions (before LVM-Thin) you could just backup out of the box and didn't need to worry about partitioning. That was better IMHO. Will...
