Ahhh, never mind. It may be useful/supported with thin LV.
I am completely confused.
Are you sure TRIM and DISCARD are needed for normal HDDs ?
because whatever I find on the internet says that I should use that when I have a SSD.
The difference here is the "thin-provisioned" lvm. In this case the
Trim/Discard isn't being used
to extend or improve the performance of the underlying hardware. It is being used to
free/return
unused blocks to the "pool".
