Description of problem:
lvmvdo(7) mentions the usage of discarding with with vdo pool lvs, however it doesn't mention any lvm commands or options to make it happen. I noticed the flag '--discards' doesn't work with lvconvert or lvchange when dealing with VDO volumes. Is the only way to interface with these volumes to mounted an fs on top and using fstrim?
[root@hayes-01 ~]# lvconvert --yes --type vdo-pool -n vdo_lv -V100G --discards nopassdown vdo_sanity/vdo_pool
Command does not accept option: --discards nopassdown.
[root@hayes-01 ~]# lvchange --discards nopassdown vdo_sanity/vdo_pool
Command on LV vdo_sanity/vdo_pool uses options that require LV types thinpool .
Command not permitted on LV vdo_sanity/vdo_pool.
