raid

I have a very specific and strange problem and ita kinda urgent to solve it in a timely manner. Yesterday I encountered a kernel panic on my proxmox server looking at server management logs apparently there was a power outage and ups was out of service for maintenance booting to the default...

Hello! I'm considering picking up an Asus Barebone PN52 for a low power homelab (I have an enormous homelab, but electricity prices has gone up, so I can't keep it up at the moment). It can fit an NVME drive as well as a 2.5" drive. I am considering getting a 1TB SATA SSD (Samsung 870 EVO...

Hello. I am having big IO delay problems using Proxmox 7.2 and i see major speed issues, sometimes VM appearing to freeze. My current configuration is CPU : AMD Ryzen 7 3700X 8-Core Processor RAM : 64 GB DDR4 HDD: 2x12TB TOSHIBA MG07ACA1 (configured in software RAID1 probably) Speed...

Hi all, I've been searching for a solution for the past week and I'm still running around circles. I'm running ProxMox 7.2-11 on a Dell T710. The server used to have 8 1GB drives in RAID5 (total space 7TB). When installing ProxMox I've created a 7TB LVM, which I then split into smaller...

Hi everyone! I just bought a server and installed Proxmox VE on a ssd device. Now I want to run only one VM with Windows Server 2022. The VM should be stored on my Microchip Adaptec SmartRAID 3101E-4i Controller with 4 SATA SSD devices, which I turned into a RAID10. That worked very easy. The...

I have a HP ProLiant ML350p Gen8 with a Smart Array P420i storage controller. I have 6 ST1000VN002 1TB Seagate Ironwolf drives in a RAID10. pve is installed to the RAID10 and then I am using the default local-LVM storage for the VMs. pveperf shows: root@pve:~# pveperf CPU BOGOMIPS...

Hi, I'm a new user to Proxmox, I haven't installed yet, just currently building the server it will sit on. Given Proxmox supports ZFS, should I use a RAID enabled controller, and let that deal with RAIDing the drives? Or should I use a RAID card flashed to IT mode, and allow ZFS to handle the...

We see everywhere the advice "don't use ZFS on top hardware RAID". But I also see opinions that it's a myth. This question is not about the rationals to avoid (or use) hw raid with ZFS. I'd like to hear from Proxmox community about first-hand experience with ZFS on top hw raid, especially...

Good day everybody, we would like to subsequently set up a software raid 1 on our Proxmox system with mdadm. Proxmox itself is currently installed on an NVMe with ext4, which is now to be mirrored on another NVMe. However, the following error occurs. "Floating point exception" root@pr-001:~#...

I have a trouble where mdadm autoactivates zfs volumes from VM's. I would not like mdadm to touch anything from zfs volumes. I tried to search for it since it's more like debian problem, but could not filnd a solution. Probably a filter when loading mdadm module? root@elite:~# cat /proc/mdstat...

I am wondering if it is possible to create a zfs pool on a raid0 mdadm, I love the performance of the latter and the functionality of the former with proxmox.

Hello, what do you think about BTRF in a production server Raid 1 or Raid10 ? Some one use BTRFS RAID5 or RAID6 ? ( I'm reading that is not stable ..) Thanks!

TL;DR ZFS RAID1 vs RAIDZ-1? Hello comrades, After a long trip with Proxmox 6 its time to move on to 7 now. Trying a new clean install i found the BTRFS implementation (not interested for now) and an old intrigue that I could never answer. -Why on the Filesystem options i get options like ZFS...

Dear readers, The current problem that I'm facing right now is adding a 4th disk to my raidz-1 pool. I have read some articles that it is not possible to expand your current raid pool. To give some context, I'm running 3x6TB Toshiba X300 drives in a RAIDZ-1 configuration (I know, 3 drive...

Dear Proxmox Community I recently started renting a dedicated server. The Provider allows for automized installation of Proxmox VE 6, which I've chosen. The server has 2 SSD's of 74.5G and an additional HDD available. However, the installation was done (as to be expected) on a single drive...

Hallo zusammen, ich habe vor ca. 2 Jahren meinen ersten Proxmox Server aufgesetzt um zu lernen. Mittlerweile ist er gewachsen und ich mache so ziemlich alles mit dem Server. D.h. auch alle meine Daten sind dort abgelegt und können von jedem Gerät genutzt werden. Ich denke aber, dass ich das...

Hi! I'am new in proxmox. I'am building my home lab. I have 2xSSD 480GB Samsung + 2xHDD 2TB drives. I want to made 2T drives in RAID 1. (SSD probably also) I have PERC H730 raid controller. What files system should i choose? ext4? ZFS? lvm? lvm-thin? I want to have about 3-4 VMs, with system...

Hello, I would need your recommendations on what type of raid would be the best for my PBS install, I planned to use ZFS. Server hardware : - 64Go RAM - 24x 8To (HDD, 7,2k) - 2x 1To (Sata SSD), for the OS. For the OS, I guess I will use raid-1 on both SSD (2x 1To) Regarding the storage of...

Hi, I installed Proxmox 7, and I am trying to create a new ZFS using two 1TB NVME drives via the GUI. However, I get the below error: command '/sbin/zpool create -o 'ashift=12' nvme mirror /dev/disk/by-id/nvme-Sabrent_1765071310FD00048263...

I have a server I've installed Proxmox onto that has one SSD for the main system installation. I'd like to add an identical drive in a month to mirror my base install as a software RAID-1 (raidz maybe?) so I don't have any down time for when the primary SSD fails. Can this be done, and if so, how?
