zfs

I have installed Proxmox VE and made a virtual machine with Debian 12 on it. There I installed nextcloud and gitea but I have second thoughts on my drive configuration. What I did: 1. Created ZFS pool in proxmox on dedicated SSD. 2. Created and attached disk in this pool. 3. Inside debian VM...

I have not been able to locate a definitive guide on how to configure HBA passthrough on Proxmox, only GPUs. I believe that I have a near final configuration but I would feel better if I could compare my setup against an authoritative guide. Secondly I have been reading in various places online...

I have been trying to understand if the bug mentioned with Thunderbolt devices has been resolved by any of the latest kernel updates, I’m on 6.8.12-7. I know people use Thunderbolt for many things, eGPU, NIC etc. in my case I am wanting to connect a 4 disc DAS over thunderbolt 3 which exposes...

Hello. After I discovered ProxMox I'm moving from VMWare but I'm trying to understand some key concepts of ZFS since my server RAID failed me at least twice corrupting data on my 2 SATA SSD devices on RAID 1. I'm still using hardware RAID for now, but planning to study ZFS before moving from...

Hi everyone, I’m new to Proxmox, so apologies in advance if this is a mistake on my part, but I’m encountering an issue that seems odd, and I’m not sure if it’s a bug or something I misconfigured. Here’s the situation: I had a Windows VM with two disks. The first disk was 52 GB, the main...

Hi All, Here is my scenario. I have an NFS pool on an Unraid server. I also have a MiniPC with Proxmox on it where I run all my media servers. I am trying to mount this ZFS from Unraid into Proxmox. Is there a step by step on how I can do this. I tried to go to Storage in Proxmox and add ZFS...

Hi everyone, We recently took on a client with a Proxmox-based cluster. One of the servers hosts a virtual machine running Nextcloud, which contains over 500 GB of small files ranging from 30 KB to 4 GB. The VM disk is in RAW format. During the update process (while creating a backup) of the...

Hi, I have 2 proxmox hosts each with local zfs with draid2 with 8 sas disks, 2 sas ssd nvme for zfs cache and other 2 sas ssd nvme for zfs log. The utilization of zfs cache is very low only 458G out of 1.5TB. What can I do ? Thanks!

Hello, i was just found error when i try to install ZFS, i already tried ZFS before, but after i reboot it shows error like this root@projecthome:~# uname -r 6.8.12-6-pve root@projecthome:~# modprobe zfs modprobe: ERROR: could not insert 'zfs': Invalid argument root@projecthome:~# zfs version...

Dears, I have a very strange behaviour when looking at the ZFS pool. There is a 1TB NVME in the box, this capacity was shown for a long time. Suddenly, the available capacity sank down to 355 GB for no reason. SMART status of dthe disk is okay, PVE tells me the following disk sizes: I...

There are a large amounts of improvements in ZFS 2.3.0 if you use NVME and deduplication: https://github.com/openzfs/zfs/releases/tag/zfs-2.3.0 When can we expect this release to become available?

I have a ZFS Raid1 USB HD that my proxmox 8.2.4 can see: root@pvelab:~# df <SNIP> kyoudaiHD 2726474496 762213376 1964261120 28% /mnt/giant kyoudaiHD/archives 4291559040 2327297920 1964261120 55% /mnt/giant/archives kyoudaiHD/backups 1964261248...

Hello, I am in the process of migrating some LXC containers from one host to another where I have different types of storage. The source host where the container is located has ZFS storage and the destination host has XFS (LVM). How should I proceed? I have tried to make a copy of the...

Hallo liebe Proxmoxer, ich bin derzeit bei der Konfiguration meines ersten eigenen Homeservers. Leider bin ich von der Informationsflut und den teils widersprüchlichen Aussagen, welche man in den Weiten des Internets bezüglich der Best Practices bei der Speicherkonfiguration findet, etwas...

Not too long ago, I decided to increase the capacity of my rpool, and replace it's SATA SSDs with larger NVMe disks. So I attached the two new larger NVMe disks to the rpool and let it resilver. I decided to leave the SATA disks in place until I next had the time and need to reboot the server...

Hi, I have a 5 node cluster setup with PVE 8.2.7, the nodes are using a pair of direct attached disks as an OS mirror and a ZFS pool on a 12 disk HPE D3600 Disk Enclosure using direct SAS connections to each node One of the nodes has lost connection to the ZFS pool. I am about to flatten the...

Hi, I currently have a ZFS pool of SSDs where I have some VMs on zvols (ext4 fs), and I want to create a VM with an encrypted disk that would be encrypted using LUKS and use BTRFS as a file system. I have read that using a COW filesystem (BTRFS) on a COW filesystem (ZFS) is not a good idea...

Should I use ZFS at all? For once this requires a disclaimer first: I am using ZFS nearly everywhere, where it is easily possible, though exceptions do exists. In any case I am definitely biased pro ZFS. That said..., the correct answer is obviously: “Yes, of course” ;-) Integrity ZFS assures...

Assumption: you use at least four identical devices for that. Mirrors, RaidZ, RaidZ2 are possible - theoretically. Technically correct answer: yes, it works. But the right answers is: no, do not do that! The recommendation is very clear: use “striped mirrors”. This results in something similar...

Hi, On the beginning of 2024, I set up a new storage server for my work using ZFS and Samba on Proxmox. I added to the ZFS pool a "special" vdev, which gives a really good performance when the 40TB (around 50 Million files) of data are backed up, as the file metadata can be analysed very quickly...
