After latest bunch of updates, lost my LVM...?

[TheBigAmbulance]

My system would not boot properly until I skipped trying to mount my LVM.

Here is what I get after running the LVM tool (system-config-lvm):

Creation of filesystem failed. Command attempted: "/sbin/mkfs -t ext4 /dev/Storage/Storage" - System Error Message: mke2fs 1.42 (29-Nov-2011)
Could not stat /dev/Storage/Storage --- No such file or directory

The device apparently does not exist; did you specify it correctly?

Here is the portion of my /etc/fstab that pertains to it, and looking through /dev (Storage doesn't exist?!?):

root@Daddy:/home/dpich# cat /etc/fstab | grep Storage
/dev/Storage/Storage            /media/Stuff            ext4    defaults        1 2
root@Daddy:/home/dpich# ls -la /dev | grep Storage
root@Daddy:/home/dpich#

I had installed 11.10 in November, and the first 3~6 boots of 12.04 went without a hitch.

Very Odd.....

Figured it out....

For some reason, dmraid got installed on the upgrade from 11.10 to 12.04, or some update did something....?

After I did

apt-get remove dmraid

, and rebooted, LVM came back to life.
