Newly created mdadm raid 6 cannot be mounted

I have a newly created mdadm raid 6 that was built using this command:

sudo mdadm --create --verbose /dev/md127 --level=6 --raid-devices=8 /dev/sdi1 /dev/sdj1 /dev/sdk1 /dev/sdl1 /dev/sdm1 /dev/sdn1 /dev/sdo1 /dev/sdp1

it shows when I use lsblk:

But I can’t mount it, istead I get this error:

$sudo mount /dev/md127 temp

NTFS signature is missing.
Failed to mount '/dev/md127': Invalid argument
The device '/dev/md127' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

What’s wrong? Thanks for any help.
