I am familiar with creating the regular softare raid using mdadm in rhel based distro.

However, if you want to create a software raid on lvm on the initial creation do you mark the 't' type as 8e in fdisk?

So is this correct in this example:

fdisk -cu /dev/sda

create 2 new partitions /dev/sda5 /dev/sda6

mark them as type '8e' lvm

Then create the software raid:

mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda5 /dev/sda6

YES

Then do this:

pvcreate /dev/md0

vgcreate myraid01 /dev/md0

lvcreate -n lvraid02 -L 512M myraid01

Is this correct in order/procedure for software raid on LVM?

Any help/advice would be great.

What cares about the type field in the partition table? That's a Windows thing.

My question is initially do you need to set the partition to 8e on the raid on lvm is that the correct order?


Or do you create the raid normally and do the lvm.


I am trying to confirm if correct order in procedure.

It does matter on the partition type otherwise you would not have the options in the fdisk utility.

thanks
