Básicamente recibí este error debido a las dos instantáneas rotas.

inactive Snapshot '/dev/ubuntu/rootfs_12.10_20140228_01' [6.00 GiB] inherit
inactive Snapshot '/dev/ubuntu/rootfs_12.10_20140409_00' [6.00 GiB] inherit

Para solucionar este problema, eliminé las instantáneas rotas usando lvremoveel comando.

sudo lvremove /dev/ubuntu/rootfs_12.10_20140228_01
