Encontré una forma de ampliar el / sin mucho trabajo.

Una opción es sacar un ignite y restaurarlo con distintos tamaños de lvoles, pero lo veo demasiado complicado, y todo porque el / tiene que ser contiguous.

El truquillo es el siguiente:

El lvol3 es el / y el siguiente suele ser el /home y el siguiente el /tmp. Si hay extends vacios, co mover el lvol4 y el lvol5 quedaría sitio. Se puede luego hacer un lvextend del lvol3.
