Good articles on using RAID1 with linux

Filed under: — adam @ 7:29 am

I have my big data drives on a RAID5 array, but they can’t boot individually if the array fails. RAID1 addresses that problem.

These links are helpful for migrating an existing system to using a RAID1 boot/root disk setup.

That first is particularly good, as it details how to set up the array with a failed member initially so you can get it set up, copy your data to it on the new drive, then add your existing drive to it, without overwriting your existing contents. I haven’t tried it yet, but the instructions look right. The others are about using grub with RAID1 drives.
