That command will issue fstrim on all mounted file systems listed in
fstab. It has no effect on HDD, or conventional "thick" lvm. But it does
have an effect on thin volumes, it will return no longer used blocks back

Once per week is enough for most workloads.
DISCARD is not supported. And I have a traditional HDD not SSD.
Do I still need DISCARD ?
