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...

Hello! I am struggling with a quite weird problem imho. Running Proxmox 7.4.1 (without subscription) without any issues for a long time until recently the SATA controller card locked up and I had to do a hard shutdown. Connected the 4 harddrives to the internal ports and booted up. The pool...

Hello; Having the Proxmox installed to Dell Poweredge R620 10bay; with RAID6; 8 SAS HDDs in use, 2 SAS HDDs are not in RAID; all, Proxmox: working as configured. Few days ago, bought second R620, 8bay, with 8 X 1TB SAS HDDs, with the H710 Mini in HBA mode, so no HW RAID enabled. I did not...

Hallo zusammen, ich habe ein Problem mit meinem Proxmox-Server, das ich alleine nicht lösen kann. Der Server läuft mit einem ZFS-Mirror und hat 32 GB RAM. Vor kurzem wollte ich eine ISO-Datei herunterladen, aber der Download stoppte immer bei ca. 1,3 GB. Seitdem ist mir aufgefallen, dass ich...

Why are clones not supported when using `ZFS over iSCSI`? Refer to table in: https://pve.proxmox.com/wiki/Storage:_ZFS_over_ISCSI In contrast, NFS has support for clones via qcow2. https://pve.proxmox.com/wiki/Storage:_NFS

As part of investigating different options for ZFS dataset replication under proxmox, I've comes across a tool called `pve-zsync`.This appears to be for syncing zfs datasets between hosts, a bit like how `pvesr` syncs the zfs disk images between hosts. I'm struggling to understand if `pve-zsync`...

Hello, recently, I decided to change how my NAS should work (VM with OMV ---> LXC with Cockpit) to make better use of the shared folders/files/mount because I wanted an arr-Stack. I found these awesome Tutorials Tutorial bind mounts and ZFS bind mounts. I got it to work except for the Tdarr...
