It's raw size, but the discrepancy is between 1000 and 1024.  Smartctl
is reporting base 10 size, but zpool is reporting base 1024..
960197124096.0*6/1024**4 = 5.24 TB, which is pretty close to what
zpool says.
Thanks ! It does explain it. But then again, on a pool that has been just created, I check the properties of the root dataset (I'm posting all the properties, just to display there's no child datasets or data on the pool):

Only 4.03T is available. Looks like it's the actual size, since it's zfs and not zpool. But 960197124096 bytes * 5 / 1024^4 gives me 4.366 Tb, and not the 4.03 T. Where did about 300 gigs go ? I'm really trying to understand, not to catch some questionable logic or find errors.

Thanks.
Eugene.
