# fstrim /home
fstrim: /home: the discard operation is not supported
This is the case if it doesn't work.
I tried all of the below but it didn't work.
bhyve emu: virtio-blk virtio-scsi ahci ahci-hd nvme
linux lvm: lvm or no lvm
linux fs: ext4
I'm glad if fstrim works, I can reduce zfs REFER.
zefofree is not a use case as it does not work during rw mount.
