zfs discuss - Nov 2008 - Zpool with raidz+mirror = wrong size displayed?

Hi,

I installed a zpool containing of

zpool
__mirror
____disk1 500gb
____disk2 500gb
__raidz
____disk3 1tb
____disk4 1tb
____disk5 1tb

It works fine, but it displays the wrong size (terminal -> zpool list). It
should be 500gb (mirrored) + 2TB (3TB raidz) = 2,5 TB, right? But it displays it
has 3,17TB diskspace available.

I first created the mirror and then added the raidz to it (zpool add -f poolname
raidz disk 3 disk4 disk5). There was a warning because they dont have the same
redundancy level, but thats ok for me. Or is it a problem for OpenSolaris/ZFS?

Thx
