zfs test README should suggest a test disk size
The current zfs test readme in
usr/src/test/zfs-tests/doc/README only specifies that three scratch disks are required for testing. It does not give a minimum size. If the scratch disks are too small, it can lead to spurious test failures.
There was some guidance at some point in the past of a minimum disk size of 10GiB. This is no longer sufficient, and a minimum of 12GiB is known to work (likely any value just above 10GiB would work as well, but it's probably not worth the effort to find the exact limit as long as we're not gratuitously over the actual minimum).
