Problem with Proxmox 8.2 on Dell R360 with PERC S160

[ilmik]

Hello everyone, I'm asking for your support to help me solve a problem.
I have a Dell R360 with 2 onboard disks and a PERC S160 (software RAID controller), with which I create a RAID 1, then I create a Virtual Disk using the two disks. So far, everything works fine.
The problem arises when I try to install Proxmox 8.2, which in the initial phase (where you need to select the disk for installation) shows me /dev/sda and /dev/sdb but doesn't see the single virtual disk.
Basically, it detects the two physical disks but not the virtual one.
Has anyone else encountered this "problem"?
Thanks to everyone in advance.

The issue is that the Perc S160 is a software controller, not a hardware one. Even after creating the VDSK, Proxmox continues to see two physical disks without recognizing the VDSK. I resolved this by using the physical disks directly, without the server's VDSK, and allowing Proxmox to handle the RAID configuration. I hope this can be helpful to someone.

I have this issue since 2023 , do you have a new news about using PERC S160 Software with RAID 1 ?

Hi UK SPEED,
I also initially thought it was an issue, but it’s actually not a problem. The PERC S160 works as expected.
Let me explain better: the PERC S160 is a Software RAID solution for Dell PowerEdge systems, and to keep it short, it is not supported by Proxmox.
Here you can find the list of supported controllers: https://pve.proxmox.com/wiki/Raid_controller

The solution necessarily falls into two possible options:

1. Let Proxmox manage the software RAID (ZFS).

2. Purchase a controller compatible with Proxmox and your Dell PowerEdge system.

I hope this was helpful.
