Subject: Re: [CentOS] 4 X 500 gb drives - best software raid config for abackup server?
Hi there, I am currently setting up a server that will house my
backups (simply
using rsync).
This system has 4 X 500 gb drives and I am looking to raid for max drive space and data safety. Performance is not so much a concern.
My experience with software raids in nil, so some of these may seem like pretty dumb questions.
I was thinking a raid 1 is probably sufficient.
Would it be best to raid 1 two drives each and LVM them together?
My next question would be about how to do this as I have
never done a
linux software raid.
You are in luck. I never did one before when I started too. I did a step by step procedure that covers adding and removing drives... For centos 5.x, with 4 drives. http://www.bobhoffman.com/wordpress/?page_id=44
This will take 2 drives into a raid 1, with LVM and all that. IT adds a third drive as a hot spare incase one fails. It adds a fourth as a standalone backup (good for a rync of the raid)
Just remember to wait for the drives to sync up before doing too much.
This is a step by step for newbs like me and is perfectly tailored for what you need. Let me know if you have any issues.
