Software RAID1

[jpenguin]

I wan to set up a sofware RAID1 to mirror /dev/sdb to /dev/sdc, both drives are identicle in size, and model. SDB1 is my home directory and SDB2 is my swap. SDB1 is ext4

I did google searches, but it's information overload...

Re: Software RAID1

Well, you are going to have to read and understand any instructions. You have no way around that. So, if you want to install/setup RAID1, you have to do your homework.

Have you seen this How To Set Up Software RAID1 On A Running System (Incl. GRUB2 Configuration) (Ubuntu 10.04)

The caveats are that it may or may not work on newer versions.
