Hello, we are currently in the process of migrating our vmware esxi to Proxmox. One of the next steps is migrating the samba fileserver, since it is ~3TB large, I want to set up a new vm/lxc on the pve node and transfer the data with rsync so I can switch to the new system more or less “on the...

Hello everyone, I use Proxmox and Proxmox Backup Server. I have a single ZFS-formatted 8TB archive HDD that I use with Nextcloud that's showing 97% full, a RAID1 ZFS 8TB HDD pool that I use with PBS for backups that's showing 97% full, and a RAID6 ZFS 8TB HDD pool used as a secondary PBS backup...

As a new user to proxmox (coming from TrueNAS Scale), I made a bunch of mistakes that cost me an aggravating week of time/effort. The two biggest issues I had were: Not realizing I had to export my TrueNAS zfs pool before importing it into Proxmox (which ultimately corrupted my zpool and made...

Replacement HDD gets here tomorrow. In the mean time I'd like to save the mirrored good drive from working overtime to resilver the failing drive. I also don't understand how to swap the new drive with the old drive, since I don't have any open drive bays to add the new drive to the pool...

It improves operational stability by default. Also runs nightly tests on AlmaLinux-10.1 and AlmaLinux-9.7, and ties up some loose ends in the docs. If you missed 1.17, it also improves handling of snapshots that carry a `zfs hold`. Also improves monitoring of snapshots, especially the timely...

Hi there, I'm currently running Unraid in a VM on Proxmox and passing through the SATA controllers, as well as one NVME drive on my Motherboard. I started using Unraid as an easy method to use disks of different sizes and have a cache in front. But over time, came to realize that the vanilla...

We have recently run up against an issue where large (>4GB) copies cause lockups within a Windows guest. These can be copies within the same folder, or across disks. The original issue was seen on a RAID Z-1 pool (6x 870 EVO SSD), but has been replicated on ZFS RAID-1 pool with Micron 7450. The...

Hello everyone, "Und täglich grüßt das Murmeltier" I just upgraded my kernel from 6.17.4-2 to 6.17.9-1. Sadly now I'm missing following binaries/scripts: - arcstat - arc_summary Is it possible to include them in the next releases and how can I install them now? Thanks in advance

Hi everyone, i have a kind of weird behaviour with a PBS based on a HP DL380 Gen10. Since the upgrade to PBS 4 the system sporadically "spits out" one of 10 SAS disks. Interestingly enough its a different disk every time and it's mostly just one. These disks get marked as failed in the ZFS...

I had a zpool with 4x8TB SATA drives in a RAIDz2 with a total capacity of 16TB. I updates to PVE 9 and ZFS to 2.3 and attached 2 additional drives to the zpool using: zpool upgrade <poolname> zpool attach <poolname> raidz2-0 /dev/disk/by-id/<drive1> zpool attach <poolname> raidz2-0...

Hi, We have a proxmox 8.3 host running on a fujitsu Primergy RX2540 M4 server. It's running zfs on top of hw raid which I know is not recommended, but I don't think it should lead to this behavior. It has crashed three times during the last 4 months. I was only able to capture the call trace...

I did an in-place upgrade from PVE8 to PVE9 but after the update the kernel and zfs are still showing old versions even though they both seem to have updated: # pveversion pve-manager/9.1.4/5ac30304265fbd8e (running kernel: 6.8.12-18-pve) # uname -a Linux ghar80 6.8.12-18-pve #1 SMP...

Hi everybody, I have a zfs pool that is filling up but I can't understand why But the sum of all vm disks doesn't match with used space above Only vm-1107 has snapshots # zpool list rpoolData NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT rpoolData...

Hi everyone, We’ve been deploying several new Proxmox 9 nodes using ZFS as the primary storage, and we’re encountering issues where virtual machines become I/O locked. When it happens, the VMs are paused with an I/O error. We’re aware this can occur when a host runs out of disk space, but in...

Hello all! I'm a developer with OSNEXUS. We’re excited to announce the pre-release version of the QuantaStor Proxmox Storage Plugin, designed to simplify the management of QuantaStor storage within Proxmox VE clusters. This plugin enables seamless creation and management of ZFS-over-iSCSI...

We had an issue with one disk of our ZFS-Pool. The disk was changed, pool resilvered all fine. Two errors are still remaining: root@pve1:~# zpool status -v pool: rpool state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may...
