Birth time of files are missing if file is created in a logical volume with size less than 512 MB

I have a volume group in my system, created with single physical volume.

I'm creating two logical volumes - one with size 100M and one with size 512M.

Any file created on LV with 100M size does not display birth-time attribute. LV with size 512M does not have this issue.

Any clue on why is this so?

Physical volume and volume group:

Note sure if it is relevant, but the mount options of first LV has stripe=4, where as second one does not have this. Other than this, both LVs are similar.
