raid does not recognize disk during installation

[juan_cipolletti]

Hello everyone, I am new to the promox world and to the forum, I am trying to install promox 8.0.2 on a gigabyte b450m ds3h v2 motherboard, but it does not recognize any disk and/or raid array. The manufacturer offers to add a raid driver, but only for windows installation.I appreciate any help you can give.

Best regards,

You could disable the onboard raid in UEFI (setting disk controller to AHCI or something similar) and then try software raid like mdadm, ZFS or btrfs.
Onboard raid is terrible anyway. It combines the downsides of a hardware raid with the downsides of a software raid,without the benefits.

I would either buy a proper hardware raid controller with cache + BBU or alternatively a software raid like ZFS.

Hi Dunuin, If I'm correct, I have to try to create the raid with some software (mdadm, ZFS or btrfs), I understand that this task must be done previously with some linux live ???...sorry if I don't understand, I don't speak English.

In case of ZFS or btrfs you select that as your storage when installing Proxmox VE from the ISO.
Mdadm isn`t officially supported. There you would need to install a Debian using the Debian ISO, select a mdadm software raid while installing it and then later convert that Debian into a Proxmox VE.

HI Dunuin, Sorry for the delay in my response. I was able to solve, and selected in the ZFS installation and created the RAID, working OK. Thank you very much for the help.

Best,
