https://github.com/ceph/ceph/blob/master/udev/95-ceph-osd.rules Lists the 4 variants, in your case it sounds like a normal ceph volume so the guid you want is probably 4fbd7e29-9d25-41b8-afd0-062c0ceff05d.
You will need sgdisk to set the guid correctly (part of gdisk)
from man
-t, --typecode=partnum:{hexcode|GUID}
Change a single partition's type code. You enter the type code
using either a two-byte hexadecimal number, as described ear‐
lier, or a fully-specified GUID value, such as
EBD0A0A2-B9E5-4433-87C0-68B6B72699C7.
your exec should look like
sgdisk --typecode=4:4fbd7e29-9d25-41b8-afd0-062c0ceff05d /dev/sda

This is a similar issue that we ran into, the root cause was that ceph-deploy doesn't set the partition type guid (that is used to auto activate the volume) on an existing partition. Setting this beforehand while pre-creating the partition is a must or you have you put entries in fstab.What should it be?
