From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

mdadm is the tool you can use to create and manage software RAIDs on Linux. You can also manage them with Cockpit.
If you do go with mdadm, my advice is create a partition on each drive that is slightly smaller than the drive itself, and use that as the device in mdadm. That way if you need to replace a drive, and the new one is a few MBs/GBs smaller, you’ll still be able to use it.
