Circumstances finally forced me to bite the bullet and learn something I had been putting off for too long: setting up a RAID array under Linux. I'm almost embarrassed, now that I've done it, that I waited so long because it was way simpler than I'd imagined. I thought I'd have to figure out all kinds of magic with LVM, parted, and mdadm, but I found this tutorial that showed a simple set of mdadm commands to set up RAID 1:

This was actually one of the simplest scenarios: the system had an SSD for the root/boot partition, and two 2 TB hard drives for data storage (/dev/sdb & sdc), so I just needed to set up RAID 1 and not worry about the intricacies of booting from RAID. So, software RAID seemed like the quick & easy way to go with a minimum of fuss.
Now the nagging question: is it really this simple, or does the tutorial above oversimplify and omit some important steps? Can someone with ample RAID and mdadm experience advise or provide tips on anything else I should do or lookout for?
Thanks, Gilles
