I have to install CentOS on a server with 8 140GB HDDs. I know

There are easier ways to quickly delete all your data.

Use JBOD

I mean RAID 1

I'm working with my jobs sysadmin and he wants me to do this but I don't know what I'm doing. He wants CentOS with raid 1 on a server

>>56550502
8 drives in RAID 1 is kind of overkill. Three is more than enough...
If you have decent raid hardware make an 8 drive RAID 6 and install on that, or make a six drive RAID 6 and install on a RAID 1.

Forgive me for being a retard but 'how do I do that?' and do I do it before or after I install centos?

>>56550545
you can use hardware raid if you've got it in your server, which would be the best way to go.
But you can also setup a software raid with MD in the centos installer
wouldn't recommend ZFS or BTRFS for beginners, it's a world of tears if you're not experienced.

Thanks, I don't wanna be a leech so I'll just google for a bit. Any sources I could go to learn this, or books that you guys recommend?

centos wiki (not great, kind of outdated)
arch wiki (with a grain of salt)
debian wiki (commands will be different)

Arch has some of the best docs in the game. They don't always apply to the distro you're using or the versions of packages, but they're a good place to look...

do raid10 or raid6
use mdadm

>the best way to go.
no it's not. software raid (with mdadm) is much easier to recover once things break. hardware raid is really only good if you have multiple servers and can afford to have identical hardware raid cards and/or mobos in stock to replace the broken ones.
