Bug Description

doing a fresh install on an intel z87 motherboard with the intel soft raid set up for RAID 1. The installation only proceeds if I select LVM in the how to install area along with use entire disk. The install prceeds normall until it tries to update the kernel at which point it fails to update grub and the install ceases. I suspect, it has written grub someplace it should not have. IF I try to start the insatall over it says the LVM name is in use.

There was nothing wrong with the install media.

It only took me about 10 hours to figure out what was going on. It is complex and involves dmraid and mdadm and boot repair as well as manually setting up the partitions in the installer. Grub refuses to install no matter how you set the partitions in the installer, so you have to run boot repair twice to fix everything.

It eventually ends up running in RAID 1 using dmraid.

If you do it right, you can install Ubuntu 14.04 to a software RAID 1, but it is complex. I posted the full instructions on the Ubuntu formus...... http://ubuntuforums.org/showthread.php?t=2229126&p=13047160#post13047160

It would be nice if the "Something Else" choice in the installer offered to help you set up simple software RAID sets using the included dmraid package. Something to add to Wish List perhaps?
