Fleecing on or off does not make a difference. There is no PBS instance involved. Storage is single NVME (2TB KIOXIA XG8 Series) with LVM volume. Graphs below definately show the issues, mouse cursor is at start of backup job. Memory usage is also pretty high: 87.23% (54.24 GiB of 62.18 GiB)

So..., with fleecing enabled everything is fine? Then leave it turned on and call it a day ;-) Some cheap consumer disks (SSD and NVMe) go easily into a "too slow"/"stuttering"/"high delay" mode. When such a device is really busy to supply the data to a backups job it may not be able to...

...using them. A work laptop in an office normally sees a lot more activity throughout the day than the avarage homelab, and the consumer grade SSDs in those still last for years. I think, many users on this forum seem to be applying their experience from the business world, where multiple...

I don’t have the hardware with me right now, but these are explicitly enterprise SSDs, not consumer-grade drives As I already mentioned in the previous post, I’m using the hardware exactly as it is If the RAID controller is in HBA mode (which it is in the ZFS setup), what impact is it supposed...

I do not know how many nodes you utilize. If you have only three of them: https://forum.proxmox.com/threads/proxmox-ceph-performance-with-consumer-grade-samsung-ssd.179948/post-834586

Hello all i have a 3 node proxmox cluster with ceph. each node has 2x 4tb samsung 870 QVO ssds. I have noticed my vms being really slow and i was wondering how much of that is because of the ssds. I have checked my network and everything else. Im here to just confirm if what AI assistant is...

I am looking into moving my VM storage to a NAS and am curious as to what texhnology people were using. Additionally, what drives (HDD/SSD/NVMe) are you using as well as connectivity ( 1G/2.5G/10G/10G+).

Hello Jungle! To find your new enp name (likely due to the onboard interface shift), use 'ip a' in the CLI. After you locate your new enp name, edit /etc/network/interfaces to correct the bindings for the vmbr0 interface, save the changes and run 'ifreload -a'.To make sure you'll never have to...

Good evening, I am running into some issues when trying to add a new NIC to an existing Proxmox install. My current network setup is via an onboard Realtek 1gb ethernet controller on a Gigabyte motherboard (all consumer grade equipment, in a homelab setup). I am trying to add a TP-Link TX201...

maybe your hardware raid have writeback cache ? what is your ssd model ? datacenter grade ssd with supercapacitor ? (zfs will run poorly on consumer ssd). 0% pressure is totally fine, it should be 0% to have good performance.

Thank you everyone for the help. That was kind of my conclusion. The only doubt is that from what I saw installing windows on zfs and lvm on pve2 the difference is massive, while on a native 9.1 test machine it was way less noticeable, so I guess there might also be something else at play...

you shouldn't use consumer ssd like Samsung evo with zfs. zfs is doing synchronous write, and consumer ssd don't have a supercapacitor to keep sync writes in memory cache before writing the nand cell. (it's really something like 200~400iops on theses drive with 20000 iops with datacenter...

If your system has PCIe slots and SAS cards are readily available at low prices, SAS SSDs can be purchased relatively cheaply on the used market since they are not intended for general consumers. I recommend them. *DWPD also significantly exceeds consumer SSDs like the 0.3, reaching 1 to 10...

Dear experts, I am going to take the plunge soon and install my very first Proxmox system. :cool: Target hardware is an not-so-new mini-PC (M900 tiny) with 16 GB RAM, one NVMe-SSD (128 GB) and a SATA-HDD (256 GB), all of it used consumer-grade. Intended usage is as a small home server in my...

Thanks Max for taking the time to research the info regarding HMB. Thou I knew about HMB and nvme devices I was unaware that HMB only stores some of the FTL and will constrain random reads and random writes. Actually a backup of a newly installed large vm disk should not put a very large load...

Hmm, I see—assuming that your datastore is on that Crucial NVMe SSD, I think that the host memory buffer might be at fault here, then. The problem with an HMB is that it (eventually) will cause performance to degrade during random reads/writes. I double-checked, just to be sure; to quote...

Rack server CPUs are SLOW. https://www.cpu-monkey.com/en/compare_cpu-intel_core_i7_4790k-vs-intel_xeon_gold_6140 This is what you will get. Basically what counts is the speed per single core. Your cpu may run a lot of VMs and it will NOT SLOWDOWN. But it won't be fast. Another issue I've seen...

RI is enough? I’m more expert on nutanix and they require only MU drives. In your opinion with 2 drives as cache how many performance can I get? It’s normal to get less than 1 normal HDD performance ?

It should be at least two in a mirror, if you loose your special device(s) all your data in that zfs pool is gone because all the metadata of your zfs pool is stored there. If you add ssd's and your budget allows it then i would recommend to use only ssd's for your zfs pool. You could purchase...

Case is, I am planning on user consumer grade NVMEs (Seagate FireCudas) and as far as I can read, running ZFS on non-enterprise SSD s is heavily discouraged. Its not entirely clear to me if BTRFS has the same usage linked challenges as ZFS on that grade of hardware, some say yes, some say no...
