# ID_FS_LABEL empty for luks volume

I have an LUKS encrypted partition on a disk. I would like to label it and have it available at /dev/disk/by-label. The value used is ID_FS_LABEL to create the link in /dev/disk/by-label. That value can be extracted with vol_id. The problem is that this value is empty. Is there a way for me to set this value somehow?
