Happy new year to you all!
I was in the process of moving over to Linux Mint Debian Edition 201403 from Scientific Linux 6.5 but I have had a problem post install. As I am new to Debian based distributions I have spent a few days learning how to install configure most of the software I plan to use on my server but I overlooked one area - which is where I should of taken advantage of the live DVD. That area being my server hardware.

The server has 4 SATA disks. Each pair has a software RAID1 using up most of the disk, apart from about 22Gb at the start. Then I have one LVM spanning both RAID1's. The OS and swap is installed into the first 20Gb (+2Gb for the swap) of the first disk.

All installed fine and after the reboot I logged in and started to install my software.
Code:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install openssh-server
$ sudo apt-get install mdadm dmraid smartmontools
The last one resulted in an error I hadn't seen before.

This error I believe meant although mdadm was installed my RAID was not properly detected hence my /dev is missing the LVM I need to mount to access all my data.
I managed to find the package (firmware-linux-nonfree_0.43) which needed to be updated to remove the error.
https://packages.debian.org/jessie/a...nfree/download
So now the error does not appear when I install the package but still my RAID / LVM setup is hiding somewhere.
When I run these commands, nothing:
Code:
$ cat /proc/mdstat
$ sudo mdadm --detail --scan

Any ideas on how to detect the RAID array's, so the LVM is detected and I can mount it?
Software RAID and LVM incomplete detection
If so, remove the entire LVM and start again.
