hello, I'm running an opnsense firewall guest and filesystem is ZFS, this the only "production" instance right now i have disabled some ZFS features on the guest already just wanted a confirmation that this is harmless: checksum compression encryption sync xattr=sa also should i disable the...

I am currently planning to migrate to Proxmox, but would like to find out some important things before I actually take the step. Before I ask my questions, I think it is best to describe my setup/requirements: I don't run many VMs, but a few with high IOPS and consistency requirements, as I run...

I want to share the results of me trying to mount multiple zvols in an lxc container to share them using smb/nfs/sftp The command outputs are trimmed to only include the relevant parts. Goal: Gounting ZFS-Pool into lxc Container. Prerequisites Proxmox VE 8.2.2 Container 102 (to mount to) A...

Hello, I want to shrink the size of a vm from 100G to 30G. I booted the vm into gparted and resized the partition to 29G I shutdown the vm ran "zfs set volsize=30G rpool/data/vm-201-disk-0" to leave a little overhead ran "qm rescan" and got the message that the disk-0 has no 30G instead of...

Hi, as mentioned in the title, I am running in issue when there is something wrong with my vm-storage zfs pool I just decided to move the pool from an NFS share on truenas (virtualized) to native proxmox zfs, but yesterday when I was trying to move the VM disks from the original source to the...

I have Proxmox 8.2 running CT's and VM's on Linstor - DRBD shared storage with underlying ZFS. I can create snaptshots without any problems. In fact PBS uses it to backup running containers. As far as i know snapshots is a prerequisite for converting CT's to a template ? I created a Debian 12...

I'll preface this with saying that I'm fairly new to Proxmox. I have built a couple of nodes multiple times as I've torn them back down and started over as I've learned more in my journey. Right now I've got two nodes and will be adding a third one shortly. The two existing nodes are identical...

Hi everyone, i'm a real beginner on proxmox and I have a problem with the creation of a CT. When I try to create one this message appear: mounting container failed TASK ERROR: unable to create CT 100 - cannot open directory //pool: No such file or directory I don't know why he try to open...

Hello, I am trying to repair my Proxmox installation after replacing my disks, and fail to do so :) For the background: I installed Proxmox on my laptop-converted-to-a-server, with two SSD, with a zfs pool and mirror replication across the two disks. Not much, just: One LXC container with a...

Hi, Recently I set up a monitoring stack in my virtualized K8s cluster (Prometheus, Grafana) and set up node exporters on many VMs/nodes, including my PVE and PBS nodes. Not soon after I started getting alerts regarding major page faults (hundreds over half a minute, sometimes every half hour...

Hello Proxmox community, I have a problem regarding the creation of a new ZPool. I have 6 SSDs of varying size that I want to form into a RaidZ2. The GUI is no good since you need the -f to "confirm" the wasted additional space. (I also tried with same size partitions, but proxmox only shows...

Since the auto install feature has been released, I was wondering if anyone has successfully deployed a PVE installation completely automatically using PXE boot? I have tried in the past installing using PXE boot with a `preseed.cfg` file but was unable to configure ZFS this way. I also tried...

Hello, anyone tell me how I can set the default location for vms/containers and isos/templates without using alphabetical order? It's annoying to change the location/move the disk every time when I don't think about it. For example, when I want to create a container, it still uses local as the...

Hello everyone, So I have had my Proxmox Backup Server installed and running for about 6 months now, with a RAID1 ZFS pool of 2 HDDs of 1TB each, running like a charm. I am slowly but steadily running out of space (I have prune and GC configured), so I bought 2 2TB NAS HDDs. I already swapped...

Hello! I'm currently running Proxmox 8.1 and originally had a Ubuntu Server VM set up for months, which I've loaded data on my hard drive in path /mnt/WD14-1 through two separate virtual disks (/dev/sdb1 mounted to /mnt/WD14-1/sdb1/, /dev/sdb2 mounted to /mnt/WD14-1/sdb2/). I just created a few...

Hello, I currently have 2 HDDs (WD Red Plus 4tb model WD40EFPX) and I want to but a 3rd one, I didn't start any configuration with proxmox for this 2 but I am willing to buy a 3rd one (originly I bought 3 from amazon but one arrived damaged and not working) before I start working with proxmox I...

Hi. I am fairly new to Proxmox as well as ZFS please forgive me if I misuse any terminology. I have a TrueNas server that is hosting some datasets. I would like to replicate snapshots of those to PBS. I have already configured and successfully connected the two through SSH. However when I try to...

Hallo Zusammen Ich erstelle auf Proxmox ein Windows 11 Sysprep image. Danach erstelle ich ein Full Clone der Maschiene im ausgeschalteten Zustand. Beim starten der geklonten Maschine erhalte ich oft ein Bluescreen: DRIVER PNP WATCHDOG Dieser resultiert in den Sysprep logs zu folgendem: Error...

Hello, I have been searching for a way to find a way to compare VM disk hashes. An older backup-restore test server is setup with XFS and I can easily compare VM disks with sha1sum . However, I could not find a way to do the same on ZFS which is our main cluster based on. I can list properties...

Updated-edit on bottom Hey I'm pretty new to proxmox (and zfs) been using it for about a month or two and really like it so just wanted to say thank you right away. However there are a couple things I don't fully understand, I think it will be clear after I explain what I'm trying to do and...
