Oh, they know all about base-2; it's just that disks seem bigger when
you use base-10 units.
Measure a disk's size in 10^(3n)-based KB/MB/GB/TB units,

This is normal, and
IIRC zpool list includes the parity drives in the disk space calculation

Terabyte drives are more likely 900-something GB drives thanks to that
base-2 vs. base-10 confusion HD manufacturers introduced. Using that
900GB figure I get to both 40TB and 32TB for with and
Here is the output from my J4500 with 48 x 1 TB

yours. This is used for Netbackup. As Mario just

Scoot,
This is normal, and admittedly somewhat confusing
(see CR 6308817). Even
if you had not created the additional zfs datasets,
it still would have
listed 40T and 32T.
Mark,
Thanks for the examples.
Where would I see CR 6308817 my usual search tools aren't find it.

This is my first ZFS pool. I'm using an X4500 with 48 TB drives. Solaris is
5/09.
After the create zfs list shows 40.8T but after creating 4
filesystems/mountpoints the available drops 8.8TB to 32.1TB. What happened to
the 8.8TB. Is this much overhead normal?
