...mirror (like RAID-10), not RAID-Z1 (like RAID-5) because that will perform way better. Are this enterprise grade ssd's? If you use consumer grade ssd's ZFS is not a good idea, then you probably should stick with hardware raid and LVM Thin on top for your VM's. *update* some more info about zfs

I operate a small 5-node HA test cluster on PVE 9 with Ceph. During fault-injection tests (power loss, forced resets, cable disconnects) I observed that when Ceph OSDs were located on SSDs without power-loss protection (PLP), virtual machines would occasionally become unbootable due to storage...

...100% in as a follow-up question and it seemed that there's many knowledgable people in this thread. The question: how about using consumer grade SSDs, but with a dedicated SLOG device like a P1600X M.2 SSD for those sync writes? Use-case: Homelab, general VM workloads (mixed bag of everything).

I would not use ceph with this setup because for a stable ceph cluster you should have at least 5 nodes (preferably all the same) with at least 2-4 drives on each node and 25G+ networking (LACP / MLAG) dedicated to ceph. You will need a dedicated network interface for cluster traffic (1G...

...created fresh Proxmox installations, configure cluster. As we went deeper and deeper we tried ZFS storage, then Ceph, but these consumer Grade SSD's can't keep up with the load, and right now it is working probably worse that if it was just server with Windows install on it and scheduled...

You are right, performance might also be a thing in a homelab. And this PDF proofs my point even further. While the Samsung SM863 is a "server grade SSD", it is almost 10 years old and gets outperformed in many metrics by basically all existing (none QLC) consumer drives on the market ;) But on...

Yeah that document is pretty much what I had been reading, and while I know that is more talking about workloads for the VM's etc they are pretty much adamanet about not using consumer grade stuff. Again I think I am going to go with the dell boss cards with the m.2 ssd's. Looks like Dell used...

I am curious about write amplification for OS only volumes not where you are storing your containers or vms. I have a situation where I only have physical space for 4 ssd's 2 nvme drives. In my case I am going with 4 enterprise ssd's and for the lack of finding cheap enterprise nvme going with...

Hi everyone, I’ve built a Proxmox server on an Intel NUC 12 (i7-12650H, 10 cores / 16 threads) with 64 GB DDR4 Crucial 3200 MHz RAM. For storage I currently use: NVMe Crucial P5 Plus 2 TB (ZFS, small/light VMs) SATA Samsung 860 QVO 1 TB (main VMs) USB 1 TB drive (used for occasional backups)...

Hi all, firstly I know this is going to be an essay to read but I figured better off answering as many questions as possible upfront. I wanted to get some feedback and suggestions on how to make best use of my setup. I'll list my setup information and what I'm trying to achieve below. I do have...

Hmm. I don't have one, but from my experience, a bare metal install of PBS is straightforward and uncomplicated. For my homeprod setup I have been running PBS on a Lenovo M910Q with a consumer grade Crucial 2TB SSD for the better part of three years with no issues. So I would like to think...

The 8 servers gone to 8 separate schools which do not have other server side components (like a NAS for bulk storage), and the school central is poor, cannot afford much more hardware purchase. This is also why the HDD mirror build in the first place instead of (server grade) SSDs. As I...

You will get no benefit from putting the boot partition on an SSD drive. You may also want to investigate faster storage solutions instead of keeping VM data on a HDD mirror. Almost nothing could be slower. I really prefer to keep as much of my data on a separate NAS as possible. And in my...

Hi, I'm running a PVE 8.4.1 3-node cluster that I mostly use as a lab for a team of 10-15 developers to practice and train on. The rough specs of the 3 machines are: HP Z6 G4 - single Xeon Gold 5220 CPU - 384GB 2666 memory HP Z840 - dual Xeon E5-2699 V3 - 512GB 2133 memory HP Z840 - dual Xeon...

There's a big difference between consumer and DC SSDs depending on what you use them for. One example. Also see table here. The source of the picture from that first link is here.

It bears stating that for most users in a homelab, all these logs are pretty unimportant. There unfortunately isn't any control in the UI to turn off persistent logging, but it's not incredibly difficult to do so from the command line. That might make this decision easier for a home user. Where...

Oh, and I remind you that in Windows Server there is no compression enabled by default! Don't give up on Proxmox! The staff has done an extraordinary job and we are confident that if there is indeed a problem, they will solve it! We must support them, including by subscribing to the system!

Hello JordansGhost. I think I should have opened a topic for my question and not inserted it in your post! I'm sorry. But, did you test with the compression on ZFS turned off? I had significant gains with the compression turned off in ZFS on the host. In my case, especially with a VM with...

To my original post. Further testing has shown 8.4 has dreadful performance on the internal SSD (1TB consumer grade as its a small 3 node cluster system in the house) however it has worked fine for 6 months. It does not matter whether I format it ZFS or LVM-Thin. I get 40-60% IO issues and the...

Really need the specs in terms of DWPD or total write endurance / size of drive. Generally 0.7+ DWPD is plenty for backups that are once a day. Most of your data will not be changed by PBS, only the indexes. Even if expect your backup rotates out every 30 days (ie: a log server with 1 month...
