I have been trying to install Ubuntu 12.10 on a Dell r710. I have 6 disks in each 2 TB. I setup a raid 5 in the HW raid controller with all drives, and proceeded with the OS install. When the partitioner runs it fails to create / for some reason. I then tried just setting up a simple raid 1 with 2 drives in the HW controller, and doing the OS install again. The installer runs fine this time. Once trying to boot I then get a kernel panic of 'Target File System doesn't have requested /sbin/init' as well as a bunch of 'deleted inode referenced'. Can someone tell me what I am doing wrong here?
