Reinstalling from the same ISO, I used guided partitioning to completely wipe the root partition and reinstall the system. At the same time, I also told it to mount the array.
After installation, my array is mounted and I see this in /etc/fstab: # /media/raid was on /dev/md0 during installation UUID=c3cc60a8-e441-4c68-a59d-ee6bacaf1e34 /media/raid ext4 defaults 0 2 Sure enough, the array is now assembled as /dev/md0. Of course, I shouldn't have to do that when I told mdadm that I wanted the array to be /dev/md0 in the first place. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/964052 Title: mdadm: created as /dev/md0, becomes /dev/md127 after reboot.
