In my homelab have a Dell R720 server with an H710 RAID controller installed. I built a Raid5 array using the onboard controller with 8 4TB HDDs. I was able to create a partition in fdisk without any issue, but when I go to mount it I receive the following error message:
~$ sudo mount /dev/sda1 /mnt/raid_array/
mount: /mnt/raid_array: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.
I'm not sure what this error means or how to resolve it. I'm almost certain it's not a bad filesystem, but I'll include screenshots of everything I can think of as relevant.
Here's lsblk:
$ lsblk
