zfs

I have a single node install with PVE 8.2.4 and ZFS Mirror as boot drive. I was doing apt update and was suggested to do a apt --fix-broken install. I ran that and got this: root@pve:~# apt --fix-broken install Reading package lists... Done Building dependency tree... Done Reading state...

Hello everyone! We currently have a PBS server in ZFS with a mirror pool (2 x 4TB HDD 7200trs 128mo cache). We would like to add a second one to that pool (mirrored vdevs striped) in order to gain performance (RAID10-like). Our idea is also to improve Garbage Collector performance (maximizing...

I have a PVE host that is currently reporting that "local-zfs" is nearly full. There is only one guest with one virtual disk stored in this pool; the virtual disk was originally 50TB and I have since reduced it to 43TB using zfs set volsize=43T rpool/data/vm-301-disk-0. Anyone experience this...

Hi pve users, I recently finished installing my services on the proxmox server running on zimaboard 432. The installation is on two mirrored SATA disks with ZFS. Since I have the version with 4GB of soldered RAM, the memory runs out immediately, at the moment I only use four containers which...

We moved the hardware we had on-hand to Proxmox a year ago and now looking ahead to what's next (Fine tuning, improve reliability, and best practices). This is for a small business of around 10 users with a small amount of data (1.5 TB). The data is mostly spreadsheets, documents, and Access...

Hi I've brought Minisforum MS-01 and have been running proxmox from last 4 months on a single Samsung 3.84TB PM9A3 U.2 SSD drive stably. Now, I've brought 2 more Samsung 3.84TB NVME SSD PM983. The device has 3 slots 1. U.2 PCIe 4.0 x4 (max 8 GB/s) used by PM9A3 U.2 SSD (7 Gbsps) 2. M.2 PCIe...

"ZFS ate half of my RAM." - :eek: That's pretty much how it started. Diving deeper to this subject it appeared that it's very common problem. Here are few topics on this forum that I read to understand what's going with ram: "Disable ZFS ARC or limiting it" "zfs_arc_max does not seem to work"...

Hey guys, Unfortunately I had the issue that my Proxmox host was not reachable anymore, that is why I restarted it. Unfortunately after that it is not possible anymore to import the rpool. I just get two PANIC messages and the timeout messages. I let the server importing the pool for over 10...

I have been struggling with an issue for the past few weeks where using either "Move Disk" in the GUI or "qm move disk" in the CLI from one ZFS pool to another soft locks all storage pools on the host, VMs become entirely unresponsive. This only seems to happen with VMs >30GB, for some reason...

Hey folks! I'm using a ZFS pool on my machine, and I've been mounting filesystems from the pool into Proxmox LXC containers. However, I've run into a problem where if a dataset has children (e.g. `tank/media` contains `tank/media/movies`, `tank/media/music`, etc.) then the filesystems below it...

Hi guys! I currently do my backups to a NFS share on TrueNAS. But since the TrueNAS also sits in my home, I cloud sync it up to OneDrive from there. In the future I would like to switch to PBS instead, mostly just for fun of trying out new things. I have an unused i5 8th gen NUC and was...

Hi, everyone; this is my first posting here. I'm sorry if this is the wrong place to ask this. I am deploying a new server in my Organization that has Proxmox. We're a VMWare shop that is moving away from them. I have this new server with 16 3.84 TB NVMe drives that I set up in a RAIDd2 setup...

Hi guys, hope someone can help. So I have a single drive zfs pool using a 22TB Seagate Ironwolf pro. I have another 22TB drive (a Seagate Exos X22). I know I can add this to the pool as a mirrored drive, but I also need to increase my capacity, but will never do stripe. I can obtain another...

Hi! I found some comments about using Snapshots (LVM or ZFS or GlusterFS ) in Storage causes disk performance degradation ( permanent slow I/O ), but if you remove all the Snapshots, the performance is returning to normal. Has anyone here had a similar experience?

hey everyone, So rn I'm running the storage backend for my proxmox ve (8.2.4) box via zfs over iscsi. Trunas core box provides the iscsi backend. I have two storage pools on my truenas box: HDD_Pool: 4x 8TB WD Reds running raidz2 ( atime 12 and 128k record size) Nvme_Pool: 6x TB Samsung 990...

Hello, Yesterday i discovered by a complete coincidence that one of the drives in ZFS pool has completely failed without any prior notice. by a complete luck i want to check something in ZFS tab and i saw one of the pools is degraded. i go today a new 4 TB HDD and installed it, then i ran this...

Dear Proxmox Community, I have a project I wrote back in 2021 I'm re-writing with Proxmox in mind. I met a local business owner who hosts his servers on Proxmox, and he sounded interested when I mentioned I had compiled ZFS modules inside a kernel, so it sparked some interest in me to...

Hey Guys, I have scoured through the forum to try and answer my question with no success... I have 3 PM nodes running windows VM's with the storage being ZFS backed, with thin provision enabled. I noticed the 1 ZFS array reporting 17TB used, but in the VM there's 20TB storage assigned, but...

Hello, I am in the middle of trying out Proxmox for the first time. My old PC used to be Windows 10 which had 4 Hard Drives running as a Zpool, accessed by Windows. It was a pain to get ZFS to work for me using OpenZFSOnWindows, but it worked. The Zpool stored a large quantity of games from...

[TL.DR]: RAID card firmware bug seems to cause a non boot issue on Kernel 6.8.4-N-pve, works on 6.5.13-5-pve. Any ideas on how to fix? Today I have done a lot of troubleshooting for one of my Proxmox servers. It started when I was rebooting the server after some updates. Suddenly it wasn't...
