    LVM mount relocate
    I currently have a LVM setup running. See log at the bottom of post. I wanted to use the LVM for storage so I could easily add disks to expand the storage. I made a mistake when I installed everything, since the lv 'root' is mounted at '/'. It should have been mounted at /var/share/ so when I want to reinstall the Linux distro I can get those files back easily. I'm not sure if I'm correct (it was my first LVM setup) but is it possible to achieve the same result after the install? If it's necessary I can purchase a new harddisk, but I'm trying to avoid losing/backing up all my data. Any thoughts?
