I have a pci raid controller, with two 250G drives. Configured this to work on ubuntu 11 a few years back. Have since forgotten much about the details of this configuration (i.e. software, hardware, raid type) and have recently installed 14.04. On my 11 installation, I had a 500G mount. I'm guessing it was raid0 or some other software configuration of the 2 disks.
How can I get this existing pair of raid disks working again without erasing any of the data?
