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...

Es ist mal wieder Zeit ein Proxmox VE Homeserver vorzustellen. Als Basis dient ein * ATX Mainboard ASRock B550 PG Riptide Highlight: - NIC 2.5 Gbit/s, - 6x SATA3, - 1 PCIe 4.0 x16 Slot, 2 PCIe 3.0 x16 Slots, 1 PCIe 3.0 x1 Slot - PCIe 4.0/3.0 x4 NVMe (je nach CPU) Als CPU kommt der sehr...

Hey all, So I have recently inherited an r730 that I would like to move my current r430 into. With this change the entirety of the r430 components (CPUs, RAM, HDDs, PCIE NIC, and RAID controller) would simply be removed from the r430 and into the r730. I assume the transfer should be as easy as...

I ran into a kernel level issue with the latest zfs: https://github.com/openzfs/zfs/issues/18648 (I opened the issue) According to some folks on there the issue is only existent in zfs 2.4.x and downgrading to 2.3.x should be a valid workaround until fixed. I was able to downgrade zfs to...

After being advised to use the remote-migration feature to keep QEMU and LXC templates in sync between our three clusters, I have implemented additional remote-migration tasks in our Ansible playbook which is already capable of creating and deploying the OS templates within our primary cluster...

My only point here is that the term “snapshot” has different meanings, heavily depending on the contextual point-of-view: PVE VM snapshot This is the native Proxmox function. It freezes the current status of a VM. This state can be “unfrozen” later to restore this very status via “rollback”...
