Hello everyone! I could use some help. I'm still new to ZFS and trying to troubleshoot an issue I'm experiencing. tl;dr I'm receiving i/o errors on my external backup devices when I try to use the Send|Receive commands. It is possible that 80% of the HDDs are bad, but I would like to rule...

Down another rabbit hole I go. This time, on ZFS on-disk encryption. I was surprised this is not enabled by default, but I'm a noob, so bare with me. You can run the follow to set encryption to on: zfs create \ -o encryption=on \ -o keyformat=passphrase \ -o keylocation=prompt \...

Hello, I would like to know when ZFS version 3.0+ is expected to be released and on which Proxmox version it will be available. Is it already possible to use ZFS 3.0+ via the Proxmox pve-test repository, or do we have to wait for an official stable release? I am particularly interested in the...

Hey all, when installing PVE on my Minisforum MS-01, I selected to use a RAIDZ1 mirror for my two NVMes as the root. While passing through the GPU to a Docker VM works perfectly fine, I of course lose display functionality on PVE itself. This should be perfectly fine most of the time, but if...

Hi, it's me again. Dear forum friends, Today I'm here with a question that has me thinking and that I can't seem to make sense of. I have a server with very good hardware specifications. In fact, I posted about it a while ago to see if I should install ZFS in RAID 10 to host my VMs. These are...

Greetings, good evening, fellow forum members. The company I work for is in the process of acquiring a High-Grade dedicated server from OVHCloud. I've previously worked with servers from that provider, but smaller ones from the Advanced range, using Proxmox and installing with the ISO without...

Hello everyone, We recently completed a migration from ESXi to Proxmox. The migration went smoothly, and everything worked perfectly. However, after one week, we noticed two different storage views in Proxmox, and we're unsure which one is correct. One view shows only 900 GB free, while the...
