I have tried gparted live, so partitions are not mounted, but I cannot apply any change in main partition (because it's lvm partition I am afraid)
This are the details
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 499711 497664 243M 83 Linux
/dev/sda2 501758 976771071 976269314 465.5G 5 Extended
/dev/sda5 501760 976771071 976269312 465.5G 8e Linux LVM
What I want is to give some extra space to /dev/sda1
