If I do an fstrim /mount/fs and this is an xsf directly on a rbd device. I can see space being freed instantly with eg. rbd du. However when there is an lvm in between, it looks like this is not freed. I already enabled issue_discards = 1 in lvm.conf but as the comment says, probably only in case of lvremove. Is it possible to get fstrim working with lvm?
