I have a ubuntu server with samba already set up and installed with a 1tb hdd. I am wanting to now install 3 more 1tb drives and create a raid array using raid 5.
I have found a lot of documentation about installing raid when installing and setting up ubuntu server for the first time. However, I am struggling to find anything on installing a raid 5 array on a system already installed an configured.
Can this be done, or does a clean install need to be done again?
