Vejamos no exemplo abaixo como aumentar uma partição LVM, que está dentro de uma partição Extended. No exemplo abaixo, recriaremos a partição da LVM, que deve iniciar a partir do mesmo setor antigo, ou seja, em nosso exemplo o setor inicial da nossa LVM é o 501760, sendo assim a nova partição redimensionada deve-se iniciar também no setor 501760.

Em seguida basta reiniciar a máquina para que as alterações sejam aplicadas, e então redimensionar o Physical Volume de nossa LVM:
shutdown -r now
pvresize /dev/sda2
