zfs

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...

Hi all, We're running into a limitation in the GUI when trying to clone a vm from a snapshot on ZFS storage. On LVM this works fine, I know this works a bit different and also allows for non-linear snapshots which ZFS doesn't. A full clone however should be possible in my AFAIK. I'm able to...

I rebooted one of my HA boxes over the weekend, and a message popped up at the BIOS level that one of the 2 SSD drives is 'near life end'. The system has 2x240GB SSD drives in a ZFS RAID 1 (created during install by Proxmox). The mfg. is sending me a new drive (actually 2) as they appear to be...

It just occurred to me that the Reason why I'm getting such a MASSIVE overhead on my Backup Server (which has 2 x RAIDZ-2 x 6 Disks each) is because the Default ZVOL on Proxmox VE is (or probably "was" for a long Time, and many of my Virtual Disks are quite Old) 8k, which results in a Space...

I have a Proxmox (currently running version 8.3) server, that was installed on ZFS RAID1 a few years ago, booting Legacy BIOS mode. There is a 512MB EFI partition present on the boot drives, but when I switch the BIOS to EFI boot mode. nothing happens beside the EFI shell starting. Searching...

Hello, I have a very strange problem. I have two PVE 8.3.0 nodes with AMD Ryzen CPU's, 64 GB RAM, 1 TB NVMe with ZFS and 2x 2,5 GBit NIC's on each node. All VM's replicate from node1 to node2 every 15 minutes. Node1 is the primary node, node2 was just added. When I try to live migrate a VM...

What's shown in the dashboard for "Free" space (3.99TB): How much space is actually "Free" (1.70T): How can i get the dashboard to show this statistic accurately?

I see the last update to this topic was almost 3 years ago so I will stir it up again. I have a Proxmox cluster of desktop PC's running 8.3.2. Node 3 was previously running Ubuntu 22 with ZFS, 4 x 4TB raidz1 drives and 4 x 10TB raidz1 Vdevs (zdevs?) combined into a single volume of about...

Hi community. I've just installed latest proxmox ve on a small server with 4 SSDs connected to the backplane. I chose ZFS RAID10 in the installation to have everything on these 4 SSDs. I updated, restarted etc and when I just wanted to deal with vms I realised that local-lvm has status unknown...

Hi, I know barely enough to make my life difficult and yes, searched, read, tried many steps found here and elsewhere. Essentially, mounting a mirrored zfs dataset in a container to run Samba file sharing. Saw this guide: https://blog.kye.dev/proxmox-zfs-mounts and followed it. Next steps...

Hello! can i delete a snap like: STORAGE/VM/KVM/vm-122-disk-0 STORAGE/VM/KVM/vm-122-state-prenelarge simply: zfs destroy STORAGE/VM/KVM/vm-122-state-prenelarge ? Thanks

Good day, I have renamed a ZFS dataset that contained a lot of snapshots. I just used zfs rename tank/data/mydataset tank/data/newdataset to rename the dataset and it looks like it worked. Also when I list the snapshots using zfs list -t snap, they are still all present, even with the correct...

I have a proxmox cluster v 8.3.1, each node has a boot drive (rpool) and 2 SSDs mirrored with ZFS (vm-storage0). Under cluster>storage there are listed local, Type directory local-zfs, Type ZFS vm-storage0, Type ZFS root@prox3:~# zfs list NAME USED AVAIL REFER...

I want to re-install proxmox from scratch, but use another two disks in a zfs mirror on the same machine. While installing, it tells me that there is already a zpool "rpool" and therefore I cannot install proxmox. Anyway, I chose to rename the pool to something like...
