Hello everyone, First of all, thank you for stopping by. Just to be clear: this thread is not an advertisement, a comparison, or any criticism of vzdump and Proxmox Backup Server. They are phenomenal, industry-standard tools built by people who know this platform far better than I do. If you...

This tutorial might leave out some details, and in parts be written a little bit sloppy. Sorry if you don't like that writing style, sorry. If you have suggestions on how to edit it to make it better, feel free to add stuff. There seems to be a lot of misunderstandings, when it comes to ZIL...

I am sharing a quick summary and the corresponding PHP code that I found helpful. After installing php-cli, this script provided clear insight into my current thin provisioning status. I hope this proves useful for anyone managing similar storage configurations...

Hi, Proxmox VE 9.2 running on a 2U, 4 nodes test cluster. All 4 nodes started with an SSD as the boot drive (ext4/LVM). 3 out of 4 have a 2TB mechanical drive to experiment with ZFS replication, all with a pool called "local-zfs01". I added a mechanical drive to the 4th and started adding it to...

OSNEXUS has released v1.1.2 of the QuantaStor storage plugin for Proxmox VE. It adds QuantaStor appliances as a native PVE storage type for VM disks and LXC containers over iSCSI. It installs as a standard Debian package and registers through Proxmox's custom storage plugin interface as storage...

Hi! First, a quick disclosure. I'm one of the developers at Hetman Software, a Ukrainian company that has been developing commercial data recovery software for over 15 years. I hope this doesn't come across as self-promotion. I'd like to propose a technical experiment, get feedback from...

I have successfully been using a privileged lxc to export NFS shares for quite a while. Each share exports a separate ZFS dastaset. Mounting those shares on a Debian 13 desktop system, all file operations worked apparently flawlessly. My client fstab specified NFS vers=4 but I believe v4.2 was...

I am setting up a new proxmox node that will run as all-in-one. It will have database (SQL-server) vms / lxcs self-hosted AI (ollama + Blackwell 4000) I have a mini-itx board with 1 pcie that will be populated by the GPU. It also has 2 m.2 slots that I will use for storage. What would give...

Hello all! New to Proxmox, so forgive my ignorance. I'm looking to have my server sent for colocation and will have proxmox installed for multiple VM's. My main goal will be for small vm's for linux, small game servers, or just general usage. My issue is that I have 8 total enterprise SSD'S. I...

Hi, I have a JBOD server with below configurationn -> - I have two datapools. Each are under RAID-5 - Proxmox VE is installed on the server and these two RAID-5 datapools are attached to it as ZFS shares DATAPOOL-1 and DATAPOOL-2. - TrueNAS 13 is installed as a virtual machine over Proxmox VE...

Hi, I followed the "changing a failed bootable device" procedure. I did this because smartd started warning me daily about 24 offline uncorrectable sectors (and then went down to 16). While the resilver, I saw some failures on the *new* drive: # zpool status -v rpool pool: rpool state: ONLINE...

Hi everyone! :) On PVE 9.1, with zfs-2.3.4-pve1 and zfs-kmod-2.3.4-pve1 I suddenly had a storage (non-OS) zpool suspended, due to I/O errors on "ata3" (1 of 2 disks of a ZFS mirror). I was able to copy several hundred GBs of data onto a backup from that suspended zpool (still showing both disks...

Hallo, ich habe bereits einen kleinen pve seit ein paar Jahren im Einsatz. Nun würde ich gerne einen zweiten aufsetzen, u.a. auch zum Datenspeicher. Es handelt sich um einen HP 800, mit 2 NVME, 1 SSD, 1 HDD Die Installation habe ich auf der 2 TB NVME vorgenommen und dabei, nach vielem Lesen...

Hi, what are the caveats for using a ZFS Pool with SAN LUNs ? is this a supported setup for production use ? are there similiar issues as with ZFS with a local HW RAID controller (in non IT mode) ? assumption: 1 node per zpool (no shared LUNs)

Hello I've a serious problem with a PVE/PBS Node. 2 Windows VM that continuously log problems with Storage and sometimes they crash. Hardware/Software: Dell R440, PERC H730P (Non-RAID mode / true HBA mode confirmed via iDRAC — Controller Mode: HBA) Controller firmware: 25.5.9.0001 (confirmed...

I'm attempting to migrate a VM with a 650GB ZFS disk from a pve8 to pve9 host. When first trying to migrate the VM, it failed with the following: () 2026-07-22 09:36:45 use dedicated network address for sending migration traffic (<ip>) 2026-07-22 09:36:45 starting migration of VM 104 to node...

Hi everyone, Since Proxmox doesn't leer disk from the GUI, Iwrote a Bash script that automates the whole process. It runs entirely on the host with the guest stopped, so there's no GParted or live-CD juggling. It handles the tricky parts (filesystem, partition table, and the underlying host...

I have a pool made up of 4x NVMe drives, each with a capacity of 960GB, and two VDEVS each with a two-way mirror. The filesystem containing my VMs have a record size property of 64k, while the pool's ashift size is 12. Other than the massive fragmentation the pool is showing, I see a pretty...

Is it possible to use a ZFS dataset on an external harddisk as removable PBS datastore? The disk contains a zpool that holds a PBS datastore, say zpool/pbs-ds. The zpool also holds other zfs datasets, say zpool/data1, zpool/data2, etc. Adding the datastore to PBS as a local datastore with the...
