Or not, maybe your encryption+compression has triggered a Shannon =

Now, seriously.  I=E2=80=99ve seen odd size reports for cache drives =
before. Can you try running =E2=80=9Czdb=E2=80=9D and
see where the wrong size is reported?

Maybe detaching and reattaching the cache drives from the pool might =
help, in case something related
to the cache drives is creating the confusion.
