Looking a bit deeper:

866,531,584 blocks * 512k/block / 1024 (kb) / 1024 (mb) = 423111MB or 413.2GB (roughly)

Right Sized Space:  423111 * .9 (10% WAFL reserve) = 380800 MB or 371.875GB

FWIW you should always look at the ‘used’ column in sysconfig –r, and it’s always reported in MB…

Really?  I thought it would be closer to 465 or a maybe only a little less after format.  Most of the time they count 500GB to be 500,000,000,000 bytes and then you get to lose your 1024x3 to make it the real GB. (10.24x4 will give you a number too small, even taking into account the movement of the decimal point)

...but I could be wrong

After format it's about 425 GB

After the WAFL right it's about 370 GB
