I recently purchased a shiny new System 76 laptop with two 1 TB SSDs. I wanted to set up the beast using LVM and RAID1. I re-installed the system using the server version of 14.04 so I could have the installer create the raid and lvm. I followed this blog post - http://blog.miketoscano.com/?p=307, and the steps in the installer to create the raid and then the lvm, and then install the OS, and it all seemed to work. I then installed the ubuntu-desktop and then the system76 drivers. It all seems to be working.
However, I cannot find mdadm. It does not appear to be installed. I looked at /etc/fstab and I see
mark@tsunami:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/mapper/vg1_tsunami-root / ext4 errors=remount-ro 0 1
/dev/mapper/vg1_tsunami-swap none swap sw 0 0
And the free space shows
mark@tsunami:~$ df -h
df: ‘/run/user/107/gvfs’: Permission denied

There is no mdadm.conf.
mark@tsunami:~$ sudo locate mdadm
[sudo] password for mark:
/usr/share/bash-completion/completions/mdadm
And mdstat does not seem correct from what I have read.
mark@tsunami:~$ cat /proc/mdstat
Personalities :
unused devices: <none>
Am I missing something? Do I really have what I intended to install?
Thanks!
