[SOLVED] Help understanding why Proxmox thinks my drives are in a RAID and how to change that so I can use them

[karlm]

I have an Asrock motherboard with an AMD Ryzen processor - the bios is specifically set to not provide RAID support.
I have two nvme 1TB SSD's on the motherboard and 10 2TB 7200 RPM drives hooked up to a SATA expansion card which specifically states:
Supports: Storage pool with 16 x SATA disks, or configure Software RAID in Windows/Mac OS/Linux.
Limitations: Does not support Hardware RAID or OS booting

i installed Proxmox 8.4 using the 1TB drives in ZFS for the install, and on reboot the 10 SATA drives show as
/dev/sda to /dev/sdj of type Hard Disk and usage ddf_raid_member

The disks were part of a RAID on a LSI controller in my ancient dell server, if that helps explain this?

I just want to use them as a new ZFS configuration, but Proxmox tells me that I cannot as I have a hardware backed raid

This is the SATA Card:

Thanks in advance

Amazon did say they'd take the card back and want me to ship it by the 16th but if I can gte past this problem I'd rather keep it than fish all the cables out of my system

Maybe this is just a generic warning that everybody sees when clicking the 'Create: ZFS' button? I also see "Note: ZFS is not compatible with disks backed by a hardware RAID controller. For details see the reference documentation." even though I have no hardware RAID. This has tripped up people in the past.

EDIT: If it's not that then please show the exact error message and maybe a screenshot as "Proxmox tells me" is not very specific.

I did see that I can wipe disk for all ten of them. I may as well do that as they were 10 of a 12 disk raid before.
And now I can create a ZFS - DOH!
Stupid FNG issue

This is the generic warning I mention and it does not appear to apply to your situation.

You might need to wipe those disks as Proxmox thinks they are already used, which explains the "No Disks unused" message in the other screenshot.

Glad to see that you managed to resolve the issue. Please edit the first post and select Solved from the pull-down menu.
