Linux Virgin here need help setting up software raid1

[Nazarah24]

Hi, i'm trying to install linux and set up software raid 1. I'd like to use ubuntu/server 18.04 and the system only has 2 identical drives so it would need to be installed on the array. It's for a testing game server (want to get more familiar with linux) I tried installing ubuntu first and there was no options in setup and then i tried and failed using mdadm. Then i saw something about an alternate install/iso and tried Ubuntu server got as far as the partitioning section now i'm stuck again. I have no clue what i should be doing i'd really appreciate someone to hold my hand lol

What you're trying to do is not trivial on ubuntu. Fedora and centos at least give you the option of using btrfs during the installation process.

 

with ubuntu, you can try to follow this guide.

That's how I created my raid

 

sudo  apt-get install mdadm

 

mdadm /dev/md0 --create --level=1 -n 2 /dev/sdb1 /dev/sdc1

That's great, but you can't do that either during or before installing the operating system

Ubuntu uses GRUB though, 1804 used GRUB2 which your article says the following about:

Although normally present, it may not be present for GRUB 2. In order to circumvent this problem a /boot filesystem must be used either without md support

So yeah, you might actually need to install the package in order for mdadm to work.

Nobody is saying you can't boot off of a raid setup, the question is: how do you set it up using the ubuntu live environment, while also being able to install ubuntu on it?

Personally I wouldn't, I found software RAID a hassle when I tried it.  As someone not yet familiar with Linux, I would strongly recommend just using it without until you are more comfortable.

 

What sort of game server are you planning and are you sure RAID is of any real benefit for it in the first place?

just noticed this got any replies lol i managed to get it working by using an older ubuntu server 14.something. Then used the get app ubuntu desktop command then updated to the latest
