Freshly created logical volumes show large usage

I created a couple of logical volumes of around 2.0G size for practice and then created GFS2 file systems in these.
There are eight physical volumes from which two logical volumes have been created.
# vgs

IACVG 8 2 0 wz--n- 7.46g 3.46g
Each logical volume is of 2.0 GB size.

# mkfs.gfs2 -t IACcluster:IAClock2 -p lock_nolock -j 4 /dev/IACVG/IACLV2
Then I mounted the volumes.
# mount /dev/IACVG/IACLV1 /mnt/lv1
# mount /dev/IACVG/IACLV2 /mnt/lv2
However, these volumes are showing large usages though I have not written anything in these.

/dev/mapper/IACVG-IACLV2 2.0G 518M 1.5G 26% /mnt/lv2
I fail to get an explanation for this.

The default size for the GFS2 journal is 128 MiB. You requested four journals. That's 512 MiB right there.
