I run a Windows Server 2008 machine. It is used as a file server (File Services feature), in addition to local shares I use CrushFTP for SFTP and HTTP access to my files. I would like to convert to Linux (Ubuntu at first).
What I want is to install the OS on a single HDD (500 GB) and then have a software RAID 1 with two 2 TB HDDs. The RAID 1 volume will be used only for storing, and all programs will be installed on the OS HDD.
In what stage of this setup should I make the RAID 1 volume? I have been searching around and it seems like most guides suggests making it during the installation of the OS. Is this the best way to do it, and when I upgrade with more HDDs, will I be able to extend the volume?
