Thread: recovering root password off LVM partition

    recovering root password off LVM partition

    I am needing to recover the account passwords, I am using a Live CD regarding this since I cannot boot into the recovery mode for some reason. I have a hard drive that has three partitions on it, the main one being on /dev/sda3, the issue is that I get
    Code:
    mount: unknown filesystem type 'LVM2_member'.
    How do I go about getting this resolved so I can mount the partition and change the passwords?

    I think you may need to install lvm2 and maybe mdadm into the live system.

    Indeed. You need to install the lvm2 package. You will then need to execute
    Code:
    vgscan && vgchange -ay

    Can you not get to a Grub Menu on Boot? (pressing the left-shift key repeatedly as it ends the POST process)?
