I have question regarding RAID 1. Can I setup software RAID 1 after having installed the first drive and setup ubuntu 12? I know that during server install and partitioning I can select RAID and setup then, but what I am not clear on is how in the world to setup RAID 1 after the fact? Can someone provide directions for this?

Also, can I RAID 1 two drives one being 500GB and the mirror drive being 1TB? Of course the mirror drive would have a 500GB partition but that's my point.

Lastly, can one drive be on IDE and the other on a SATA controller? I know speed will be an issue, that doesn't matter, I just need to know if it will work without corrupting data and if it's the same process?

Thanks.

Hi all, I'm looking to replace my hard disk, which is a Seagate Barracuda 7200.11 ST3500320AS 500GB. My friend told me to get a SATA HDD, not a SATA-II. What is the difference between the two?

Let's assume you've got a box like one of these with space for 24 SATA disks. What are the best bits of advice for deploying this? For instance, should you be greedy and go for the 1.5 or 2tb disks or are they just not reliable enough to be used in an array like this and you should stick with 640gb… >>> More

My MacBook Pro runs slower the longer it's on. I am getting kernel warnings. The resets correlate with AC power connects and disconnects. I don't know if the warnings do. (How do I tell?) Are these bus CRC errors? Or something else? Can this damage the drive or corrupt data? What is it seeing… >>> More
