I am hoping to build and migrate to a software raid 5 array. I am working with ubuntu 12.04.1 LTS 64-bit. I currently have three drives:
- /dev/sda1 which is a 60G solid state drive which contains my root directory and serves as my boot drive;
- /dev/sdb2 which is a 1.5T standard hard drive that mounts in my home directory and acts as my main storage and also contains swap space;
- /dev/sdc1 which is a 1.5T standard hard drive that mounts in media which I have been using for back up.
Now that /dev/sdb2 is full I am reconsidering my data management approach. I am considering buying another 1.5T drive and using it with the other two to form a single RAID 5 array hopefully mounted in my home directory. I would like to migrate to the array without destroying the data currently held on /dev/sdb2.
How should I go about doing this?
