I am going to Kickstart a CentOS 7.x installation with software RAID 1 remotely for the first time. So I am kinda inexperienced at this and wondering what I need to make this work correctly.
A CentOS 7.x kickstart with hardware raid, I use the following partition configuration:
# Disk partitioning information
part biosboot --fstype=biosboot --size=1
part /boot --fstype=ext4 --size=1024
part / --fstype=ext4 --size=10000
part /vz --fstype=ext4vz --size=40768 --grow
part swap --size=4096
This works very well.
However since I have never ever done a software RAID 1 on CentOS in general, I am wondering what the correct commands are to do so? I did some searching, but most tutorials / information I found on Google is pretty dated or uses LVM (Volume Group), which I don't want.
I want the exact same thing as I have above, but this time with software RAID 1.
Can someone give me a workable example of how this can be done? And do I need to make changes as well to other aspects of my Kickstart configuration? E.g. bootloader configuration.
Oh and I don't use EFI. Don't know if that is important to mention.
Sorry for popping the question. I did search, but couldn't find any workable information and/or examples to experiement with. And as I said; I am doing this remotely and I don't have direct access (well unless I drive).
Thanks in advance!

I wanted to give it a go on a local test machine with 2x 120GB SSD's in software RAID 1. So I went through the CentOS 7.x installer by using this tutorial for the CentOS 7.x installation GUI.
Well after a wait, I rebooted and apparently it was setup correctly:
Filesystem Type Size Used Avail Use% Mounted on
/dev/md127 ext4 9.5G 4.7G 4.4G 52% /
devtmpfs devtmpfs 1.9G 0 1.9G 0% /dev
tmpfs tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs tmpfs 1.9G 9.7M 1.9G 1% /run
tmpfs tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
/dev/md124 ext4 74G 53M 70G 1% /vz
/dev/md125 ext4 488M 149M 305M 33% /boot
tmpfs tmpfs 379M 4.0K 379M 1% /run/user/42
tmpfs tmpfs 379M 48K 379M 1% /run/user/1000
tmpfs tmpfs 379M 0 379M 0% /run/user/0
So since this was setup correctly I decided to take a peak at the anaconda-ks.cfg file. No partition scheme in there. Okay, so I checked the next file "initial-setup-ks.cfg". Same thing, no partition scheme. Sigh.
I always thought that your current setup, through the installer GUI, was reflected in those files? Wishful thinking apparently. So I am back to scratch again...

Nobody has an idea on how to do this correctly? :(
