Search results for query: ZFS consumer SSD

Dear all, I am running PVE in a what i consider being a rather typical "IT nerd" setup, a 3-node-Cluster on consumer hardware. Private use only. 2 nodes are built identically: AMD 3200G (2C/4T) APU, 32GB DDR4 RAM, M2 NVMe for OS, 2x4TB HDD for storage (connected to SATA onboard), GbE NIC 1...

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...

Hallo! Ich habe nun endlich etwas Zeit die INTEL SSDs einzusetzen. Die beiden sind jedoch kleiner als die drei Crucials, die aktuell in meinem System laufen. Wenn ich das jetzt nicht durcheinander bringe, dann laufen meine 3x 1TB Crucials als RAID-Z1 und ich möchte die beiden INTELs als RAID-Z0...

10year old ceph blog, also apply for zfs https://ceph.io/en/news/blog/2014/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/ https://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/ don't expect any good performance with consumer...

However, to be fair, I could imagine that there are probably significant differences between different consumer SSDs. So far, I’ve always used Samsung Evos (TLC) and, in one case, a Pro (MLC), and I haven’t managed to kill any of them yet, at least not with my workloads, even with ZFS. So I’d...

I'm not one of them :)

I think power-loss protection is somewhat overrated as well in a home lab, particularly if the budget is limited. With modern file systems, and modern branded SSDs it's not strictly necessary, provided you can accept the loss of any data that was "in flight" when the power went out. The file...

Watch out when doing PBS backups with that setting. If I remember correctly, PBS makes use of that. To get back to your initial question "How to reduce wear out" the correct answer IMHO would be: Don't worry! Others here recommended PLP drives, but in reality most workloads are perfectly fine...

Das Thema ZFS und SSD-Wear wird gerne übertrieben. Ja, ZFS hat durch Copy-on-Write und Checksummen etwas mehr Write Amplification als LVM — aber bei modernen SSDs (auch Consumer) ist das in der Praxis irrelevant. Die meisten SSDs halten locker 5+ Jahre im Dauerbetrieb, auch mit ZFS. Was...

Hello and thanks for your reply. I hear that too, one person on youtube apparently debunked this (for reference: https://www.youtube.com/watch?v=V7V3kmJDHTA ) but the common knowledge remains: ZFS kills SSD... I can't quite explain this, hard data seems to show it doesn't as much as one would...

Hello and thanks for your reply, is there a real advantage though? Over tuned ZVOL I mean, I see that WAF could be severely reduced by turning some knobs in ZVOL config, is that true? Because it mostly comes from (I suspect) AI generated content, I have no first hand experience with this...

(small reminder: don't use zfs on consumer ssd/nvme . they can't handle a lot of fsync because they don't have a PLP/powercapacitor), and zfs do a lot of sync. It's really like 200~1000 iops max with this kind of drive.

Hallo, meine Windows 11 VM auf der 2 Datenbanken laufen ist recht träge. Kurze Vorgeschichte: Bis letztes Jahr hatte ich meinen Proxmox auf Consumer Hardware laufen (Intel i9 12600k, 128 GB Ram, Samsung Prosumer SSD). Einige Container und VMs drauf. Es lief soweit gut bis auf eine Windows 11...

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...

Hi folks, I'm looking to use Proxmox on my home server and I'm struggling to make a decision on whether to use ZFS or btrfs or something else entirely. My home server is mostly used to backup photos (immich) and run a few services (jellyfin, paperless, home assistant, etc). I thought I had...

... und anschliessend beschreibst Du, wie man das vermeiden kann. Vermeiden kann man es nur, weil es "normalerweise so passiert". Proxmox (auf ext4 installiert) verwendet LVM Snapshots auf Blockdevice Ebene für die VMs, nicht QCOW auf Fileebene. Das als Begründung anzuführen für einen ext4...

Hallo und frohes Neues 2026. Alles Gute für Euch und das ganze Team! Ich hab nicht gehört und nun bekomme ich die Rechnung. Mein Proxmox system Läuft auf einem ZFS von ca 3TB aus 3 jeweils 1TB großen Consumer SSDs. Nun passiert es regelmäßig, dass das ganze System "zögert" also langsam bis...

Also das mit der "religiöse Diskussion" war etwas übertrieben formuliert, der Post ist bis auf die pauschale LVM Abwertung sehr hilfreich. Simple suggestive Aussagen wie "LVM ist Mist" und "ZFS killt SSD ist ein Märchen" helfen IMO nicht, da ziehe ich mich normalerweise zurück. Es wird hier...

I'm looking for some guidance here! After building many systems with SSD and Proxmox I continue to struggle to find a great SSD. Crucial, PnY, Fanxang we all know are consumer SSD. I've been looking into Silicon Power A58, but even that says its a consumer SSD, but with SLC. So does that mean...
