I configured 2 SSDs in RAID1 on my hardware controller. After Proxmox install, the RAID volume shows up as "degraded" (Fig. 1) on the controller. The SMART values (Fig. 2) reflect that one drive is being used but not the other.

I had the RAID controller "repair" the degraded mirror, but that resulted in being unable to boot into Proxmox. No bootable partition could be found. So I reinstalled Proxmox from scratch after once more making a RAID1 volume, and got the same result, a "Degraded" RAID volume.

What am I doing wrong?

It looks like it is seeing the bare drives in Proxmox.

If you can disable RAID on the backend and just pass off the drives to the OS then you can do the install as ZFS Mirror (I don't remember the exact verbiage for it) and then you have ZFS file system and it handles the drive Mirror.

It doesn't work with backend RAID though since it handles it for you. ZFS is far better than HW RAID
