I had two distributions — Fedora 20 and one Ubuntu-based distro called Deepin Linux. The partitions in Fedora were in LVM format and couldn’t be accessed in Deepin or any Ubuntu-based distros.
Here is how you mount the partition:
sudo apt-get install lvm2
sudo modprobe dm-mod
sudo vgchange -a yThen find your volume:
sudo lvdisplayMount it:
sudo mkdir /mnt/fedora
sudo mount /dev/volume-group/logical-volume /mnt/fedora
