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?

(PS. As I said this is my first time working with ZFS, if this is a dumb
question - just say so.)
Here is the output from my J4500 with 48 x 1 TB disks. It is almost the
exact same configuration as
yours. This is used for Netbackup. As Mario just pointed out, "zpool
list" includes the parity drive
in the space calculation whereas "zfs list" doesn't.
