I also get no output:

2021-08-30 23:40:44 toor at f2 ~
# pkg query %M openzfs openzfs-kmod



But the packages are there:

2021-08-30 23:42:17 toor at f2 ~
# pkg query %n openzfs openzfs-kmod
openzfs
openzfs-kmod

I do packages.

I wanted to do a trim before taking an image, to reduce the image size. 
  I guess I'll just throw hard drives are the problem for now.


Thank you for your suggestions.  :-)
