I recently acquired two used blade servers and a short rack to put them in. I’m planning to use one or the other as the replacement for a media server that died on me a bit ago. The old media server was just a little refurb dell workstation, with a single SSD in it, but the servers have 6 and 8 bays, respectively.
I would like to RAID them so that one drive dying doesn’t lose any of my media, and I was leaning towards Ubuntu server as an OS. I’m not sure how to do that, and I’m kind of poking around for info and advice. Hit me with it.
I did this yesterday for my media server on Debian and it was very easy. Use mdadm to create the raid. There are guides online on how that are very easy to follow. You may want to use partitions on the drives as another comment recommended (mdadm supports whole drives and partitions so do whatever you think is best). Next you should have a device /dev/mdX that you can format to your fs of choice. After that just use lsblk to get the uuid of the raid and mount it in fstab like any other drive.
