ssd

Hello, Currently we running 2x MX500 2TB ZFS RAID 1 which are consumer SSD's, my question is if I add two additional Samsung datacenter grade SSD's which are the PM883 with RAID 1 ZFS, can I still let proxmox run on the consumer SSD's when I run all the VM's on the two ssd grade ssds? Thanks...

Hello, i have a weird problem i cant understand, i have a couple of cheap 1tb kingston ssds (yes i know that comes with its own problems) that i have ran in SW RAID1, ive been running my VM's of this raid pool, but what i have found out is that after about 6gb of writes, the speed goes all the...

Hallo in die Runde, ich habe seit ein paar Wochen immer wieder das Problem das alle meine VM die auf den Disk "sdf" und "sdg" liegen abstützen und dann die beiden Disks gelockt sind. Die VMs booten dann ständig, aber finden kein Boot-Device mehr. Erst wenn ich den Lock entferne und ProxMox...

Goodevening, I have a question according to my Proxmox setup, I have a 128GB RAM server with 2X 2TB SSD's in RAID1 (ZFS) configured. I saw that the wear out is around 10% in 34 days, I was researching on the internet and find a possible solution to adjust the ZFS settings like: recordsize to...

Hallo Forum, leider findet man nicht wirklich viel zu dem o.g. Setup, was meine Frage sehr wahrscheinlich auch beantworten wird. Macht es sinn, aus einer 1TB M2 NVMe und einer 1 TB SSD ein RAID1 für die LXC und VM´s zu erstellen? Kurz zum Vorhaben; ich habe zwei identische Mini-PC´s mit 1x...

Hallo zusammen, nachdem ich einen SSD-Pool zu meinem bestehenden HDD-Pool hinzugefügt habe schrumpft der HDD-Pool extrem schnell, so dass vermutlich morgen ein Produktionsausfall bevorsteht. ursprüngliche Umgebung: 3-Node-Hyper-Converged-Cluster, (PVE Vers. 6.3-6) mit verteiltem Ceph (Vers...

Hi All, We have 2 datacenters, one located in each building. We are setting up a new proxmox VE HA cluster of 4 machines. The idea being if one building goes down for an extended time, the other 2 servers will be able to keep everything up. In this setup each server has 8 ssd's. one ssd...

Hello. Recently i replaced SSD drives on hosts and faced a problem. Veey slow performance in VMs. Lot of time i couldn't understand what happens. I used Crucial CX500, but bought Samsung 870 QVO (as in tests it is faster?) So, after some time i found (in experimental way) that with "discard"...

I have Home Assistant and Ubuntu 20.04 running in virtual machines and every day I come home to find the console flooded with these messages. I ran a SMART test on my SSD and it came back clean with no errors. Sometimes when I reboot the VM it starts back up fine, other times I have to run fsck...

Hi, I self-host Proxmox on a dedicated server, running on 2 SSDs in ZFS mirror + 2 hard drive with independant pool. My SMART results on the SSDs start to worry me a bit, and I'm thinking about ditching ZFS. Some recap: It seems to me the "Power_On_Hours" is incorrect. This server has...

Hallo Liebe Proxmoxer:innen, Ich mache ab Dezember eine Umschulung zum Fachinformatiker - Systemintegration und möchte mir zu den Lernzwecken eine Testserver basteln. Wenn ich Proxmox installiere verlangt dieser immer eine Swappartition, und da fängt meine Frage runde im Kopf an? Und zwar...

Hi there! I have two PVE 7.0 on ZFS, one with 12 x 4TB 7.2K SAS HDD in ZFS RAID 10, the other with 4 x 4TB SATA SSD in Z1 and they're coming out with near identical IO performance, which is suspicious! From benchmarking with FIO with caches and buffers disabled, on sequential read / writes, the...

Hello, What does it mean when I see a negative percentage in the Wearout field ? (attached)

Hello, I want to buy SSDs for Proxmox Root-FS, VMs/ CTs, and Special Device for ZFS for two 6TB WD Red HDDs. I found this model online for 115$ (used): Seagate Nytro 1551 480GB 6G SATA Mainstream Endurance Is it recommendable? I am running Nextcloud and some very small CTs (e.g. Unifi...

I have a pair of HPE DL360 Gen8 dual Xeon, 64GB RAM, 2 hdd 10k sas for system (ZFS RAID1) and 4 consumer sata SSD They're for internal use, and show absymal performances. At first I had ceph on those SSD (with a third node), then I had to move everything to NAS temporarily. Now I...

Hi there, I'm new on Proxmox and I'm installing it on my Dell R720 server. I have only one Samsung SSD 870 disk on it and Proxmox didn't recognize this disk. The iDRAC is showing the disk as Active and looks good. I tried a couple of things (youtube video, etc) no luck. Does anyone know...

Hi, we are running an older Proxmox Ceph cluster here and I am currently looking through the disks. So the OS disks have a Waerout of two percent but the Ceph OSDs still have 0%?!?!?!? So I looked into the Lenovo XClarity Controller: So for the OS disks it looks the same, but the Ceph...

Hi All, I installed proxmox (using ext4 filesystem) on a 5212MB SATA SSD (used consumer-grade Sandisk SD8SB8U512G1001) to evaluate it. I run some benchmarks using fio, to get an idea of how fast it is. Before installing proxmox, I benchmarked the disk with PassMark's Performance Test on Win1o...

Ich habe 2x die P2 2000GB von Crucial als NVMe SSD. Der Pool den ich erstellt habe heißt whirl-pool. Muss ich noch was ändern ? ich habe etwas von ashift=off gehört... wie mache ich das? macht das Sinn?

I was wondering, why the "discard" option at Hard Disk isn't set by default. Can that cause negative effects or why it's not set by default?
