Multiple partitions on a raid created randomly?

I just made a new raid mirror with MD in omv and all of a sudden like 5 other partition raids showed up. This drive shouldn't have any partitions on it, I also cleaned it before I started messing with MD. What is going on? The drive should be a 2tb drive. Meaning the extra 900gigs are coming from nowhere?

i ended up running lsblk to get my drives listed. and sure enough my drive showed a partition

i used the umount commands to make sure nothing was mounted to my linux system after going back to omv and deleting the MD

i then used sudo fdisk /dev/(the drive that was giving me issues)

deleted the drive with d then w

loaded back up then made sure to do another wipe of them through linux instead of omv just to be sure

sudo wipefs -a /dev/(drives)

sure enough some file data was on one of the drives

the other two were clean.

was able to trigger the MD to start again, we will see the success later!
