I'm aware that there are a lot of similar questions about this, I have tried following through the responses but nothing has helped. I'm more than happy to post more logs if needed.
The end goal: Have three ssds (sda, sdb, sdd) all mounted as 1 large folder but pvcreate is struggling with sda.

I've recreated the partition with fdisk -c /dev/sda setting the type to LVM (e8).
A different questions suggested overwriting the beginning of the partition with dd if=/dev/zero of=/dev/sda1 bs=1M count=20
I have also checked the LVM configs at /etc/lvm/lvm.conf and there are no filters in place.
Sorry for not providing enough detail at the start!
