http://ubuntuforums.org – I just did a new install of Jaunty using "alt. x64 desktop" disk as RAID 1. All went fine and works great, except it boots in degraded mode. I used this https://help.ubuntu.com/9.04/serverg...tallation.html and followed to the letter. I am a noob to Linux, but not computers. I did the normal diagnostics. I checked drives and cables. I can boot to desktop with ether drive connected to any port on MB. If both drives are connected it boots fine, but still shows degraded. If I run "sudo mdadm -D /dev/md1" with single drive (ether one) this is what getAttachment 130777 If I run "sudo mdadm -D /dev/md1" with both drives this is what I get Attachment 130778 If I run "cat /proc/mdstat" with both drives this is what I get Attachment 130780 I don't know how to find out which drive it is not recognizing or why. Any help would be great Please, if you give me code to run, give me a disc. of what it dose. I would like to LEARN what I am doing, not just "do this" That way I will know to do next time, or be able to help someone else.
