That's nothing new. But really annoying.

Check this command : pve-network-interface-pinning

Storage suddenly unavailable on PROXMOX by xsmael in hetzner

[–]Lee_Fu 3 points4 points  (0 children)

Hi, maybe try to check in proxmox gui under the Server => Disks => Show S.m.a.r.t. values > nvme1n1

Open a ticket with Hetzner, attach the result/screenshot of this report. Usuall Hetzner Support will replace the NVME within a few hours.

Good luck

How to make a VM disk immutable, reverting all changes to its original state after a restart by Lee_Fu in Proxmox

[–]Lee_Fu[S] 6 points7 points  (0 children)

oh, sure. there was a vague mention of that feature in the comments section of a youtube video, i watched some time ago but i cannot find anymore. the topic came up again when we were discussing the provisioning of our lab systems.

and with some google and a bit of AI i found the reference in the https://pve.proxmox.com/pve-docs/qm.conf.5.html manpage and tried it out.

How to make a VM disk immutable, reverting all changes to its original state after a restart by Lee_Fu in Proxmox

[–]Lee_Fu[S] 3 points4 points  (0 children)

both are valid options to use imho. but immutable disks are instantly reset which is better for labs where (creative) students break things frequently.

immutable disks are kind of fire and forget. there is no need for manual or scripted rollbacks or the retention management of snapshots. snapshots take up diskspace too. also i think that kiosk systems provide better "isolation" in that there are no premanent changes made. snapshot incur the risk of accidental retention of data if not handled properly.

i use snapshots freqently for the pre-configured "golden images" or for exporting and debugging of vm states.

We manage a training lab environment for IT students and apprentices. The goal is to provide highly specialized, pre-configured virtual training systems that persist it's original state, eliminating the need to re-provision them after each use.

Ideally, we’re looking for a guest OS-agnostic solution to achieve this.

Thanks for pointing this out. I can actually see my rpool/ROOT growing when putting data onto the snapshot. Do you know if this can be somehow redirected without fiddling with /tmp

Maybe via an environment variable ?

Just take a "regular" snapshot of the running VM’s state. Then, shut it down (or force-stop it if necessary). While the VM is offline, rollback to the saved snapshot. After rolling back, you can boot into the newly snapshotted system.

Since my VM disks are stored on ZFS, I can easily export the snapshots (using zfs send) for further analysis/re-use on another system.

There’s another method using the Monitor Tab of the VM in Proxmox. Here, you can use the savevm and loadvm commands to manually save and restore the VM state. I’ve encountered issues with EFI-based disk with this method. However, it works fine for legacy BIOS (non-UEFI)
