I have a 931 GB hard drive with 3 logical volumes. One for ubuntu(100 GB), One is for swap(4 GB), and the third one(891 GB) is empty as shown in the pics. The question is, how can I make a new partition from the empty logical volume (named data)?

1I do not see anything empty. Your disk has 3 partitions. You can remove sda3 and create a new one if you like.– Pilot6Aug 20, 2016 at 11:41

sda3 has ubuntu installed on the 'root' volume. I want to make a new partition from data volume, which is a part of sda3 along with 'root'. So I can't remove sda3. By empty I meant I haven't stored anything on the 'data' volume.– sagaAug 20, 2016 at 12:01

First you need to downsize sda3,and then create a new partition in the resulted empty space. You can't create a partition from another partition. LVM (Logical Volume Management) is only necessary when dealing with multiple harddisks. If you have just one harddisk (Disks app says so) LVM is quite useless.

I've deleted the 'data' volume. Now sda3 has 830 GB free space. But I can't resize the partition with gparted. it says: ' /dev/sda3 : cannot resize to 28116 extents as later ones are allocated'– sagaAug 21, 2016 at 7:34

Select sda3, right-click on it and choose Delete. Press the 'Apply Changes' button (the green check sign). Right-click on the empty space and choose 'Create partition'. Set the partition size and press 'Apply changes' button again. Aug 21, 2016 at 7:39

OK, don't delete it, choose Resize instead of Delete from the same menu. Make it smaller, Apply Changes, then click on the empty space and create a new partition. Aug 21, 2016 at 12:56
