Instllation error in Proxmox 8.2 on Dell R420

Hey all, I'm new here and trying to install ProxMox 8.2 on my homelab server to mess around with. So I started out with a virtual disk on my RAID array (PERC H310 mini) and I was initially intending to install it in ext4 mode on top of the virtual disk and let my RAID controller handle the virtual disk and the array. Unfortunately that didn't work, it would consistently fail at 100% spitting out an error saying "failed to prepare efi boot using grub". I tried a few fixes that were suggested here and on reddit but none of them worked, so I ended up flashing the H310 mini into IT mode and trying to install PVE using the zfs RAID10 and having it handle the array. According to everything that I've read that usually seems to be thing thing that everyone does and it seems to work for most people, but I had no such luck.

Once I got the controller flashed I went to install PVE using the graphical installer thinking that using zfs would be better. Unfortunately, that didn't work either. This time around, the installer failed at 3%. It seems like it was able to create the zfs array but then it immediately failed giving me the error "Unable to create zfs root pool". On suggestion from someone on reddit and a couple other forum posts I booted into gparted live, totally erased the disks and then tried again, failing in the same spot. I snapped a picture but I can't upload it here because its too large apparently. Basically its spitting out this:

Code:

So I'm quite a bit confused whats going on here. Any help would be appreciated, I really want to get this up and running but I just don't get whats going run here
 
Seems i like IO Error while installation check your RAID setup and HDD, start installing on a single disk for checkout. might help.
Hmmm I definitely could try that, but once I get it installed onto a single drive, I would have to exclude that drive from any RAID array that I intended of building right?
 
try like this:
- boot of a linux live cd, for example Linux Mint and check the smart data of the drives
- reset the BIOS to default
- go to dell support page for R420 and search for "DELL Server Update Utility, Linux 64 bit Format" load the iso on to a USB drive or load it in to iDRAC, this iso will update the firmware of ALL devices (BIOS, network card, etc)
PS: I hope that you have an UPS for this server...just in case...the entire process will take some time and is noisy
- check if there are any firmware updates for the drives
- redownload the proxmox ISO and write the image with Rufus
- try reverting back to IR firmware, see https://fohdeesha.com/docs/H310.html and double check if this is the actual card in the server
- if you wanna still try IT mode, follow the instructions from the page above and also "Optional: Boot Images"
- and for the issue with the usb drive, try not to delete the wrong drive

A single HDD can work. You can check all your HDDs, and re-installing Proxmox is not difficult; you can do it again. Make sure to get Dell support to recheck the drives.
