Logical Volume Group spread across 3 disks, not taking up full space?

[Dave_Grant]

Hi, totally new to Ubuntu but successfully installed and created a Volume Group and Logical Volume which spans 3 HDDs (1x1TB, 2xTB). My problem is that the logical volume doesn't seem to take up all the available space (5TB).

vgdisplay lists the volume group vg_media as 4.55TiB with Alloc PE / Size as 3.91TiB and Free PE / Size as 657.54GiB

lvdisplay lists LV Size as 3.91TiB

Desktop labels the volume as 4.3TiB

How can I get this to consume the full available space, 5TiB?

I've pasted full output for vgdisplay, lvdisplay and fdisk -l below. Please let me know if any other information would be helpful.

Thanks

5TB=5/1.024^4=4.55TiB. Makes perfect sense. That's the difference between terabytes and terabinarybytes.

Thanks. I've extended it out and it's listing as 5.0TB in desktop now.
