fedora lvm2 2tb ext4 hdd but physical volume shows 1.1tb used with no more free space

Question

Just over half my hard drive is used but lvm shows that there is no more free space to allocate.

How can I investigate further?

• fedora 22, ext4 file system
• 2TB hdd
• used physical space shows as 1.1TiB
• no more free space?

Answer 1

Your last partition is sized to be only 1.1TB, so you have some space on your disk that is not allocated to a partition. You have two choices:

Resize the third partition or create a new partition.

If your disk is partitioned with GPT you may also need to relocate the backup partition table to the end of the disk.

To resize the partition you need to first delete it, and then create it again from the same start sector. If that sounds scary you could use something like gparted which can do it safely. Or alternatively simply create a fourth partition in the free space.

Whichever one you choose you then need to reboot.

If you resized the partition next you need to pvresize /dev/sda3 and you are done.

If you created a new partition you should do this instead:

pvcreate /dev/sda4
vgextend fedora_2012pc /dev/sda4

Answer 2

I think you need to resize the /dev/sda3 partition to be bigger, now it's only 1.1 TB instead of the rest of the disk.
