So was just looking and for some reason nread etc for the ZFS storage 
stats.

Below is a example of a ZFS dataset being used by CBSD to store a raw 
disk image,
one that is running currently, but for some reasonn the R/W stats don't
seem actually update.

kstat.zfs.storage.dataset.objset-0x1d41.nread: 0
kstat.zfs.storage.dataset.objset-0x1d41.reads: 0
kstat.zfs.storage.dataset.objset-0x1d41.nwritten: 0
kstat.zfs.storage.dataset.objset-0x1d41.writes: 0
kstat.zfs.storage.dataset.objset-0x1d41.dataset_name: 
storage/debian10_test/dsk1.vhd

Is there any way to get ZFS to actually keep these up to date for use 
cases
like this?
