I'v ecreated Raid arrays before in LinuxMCE without any problems. I always did on a Core that was also MD. Now I installed a dedicated core and want to create again another raid array but it keeps failing (see picture). As soon as I hit the "Create Raid" button the drive status changes to "Removed" and a bit later it sais "FAIL" at arra creation. When I delete the array and make it again the disks are still there and I can add them again with the same result. Rebooting doesn't help either. Any suggestions?
