When creating raidz pool out of n disks where n =>2 pool size will get a size

newpool 139G 141K 139G 0% ONLINE -

46.58G * 3 = 139G
c1t12d0 <SEAGATE-ST1181677LWV-0002-169.09GB>
c1t13d0 <SEAGATE-ST3146807LW-0004-136.73GB>
SIZE should be 351GB and not 139GB. What happend to the rest of the space?
I have Solaris 10 06/06 patched with all patches.
Looks like if you have to use the same size of disks for raidz.
Yes, this is true for most, if not all, RAID-5-like implementations.
If you want more space, then you might need to get more clever in your
usage. For example, if you slide as follows:
disk1 disk2 disk3 raid space
--------------------------------------
46.58 46.58 mirror 46.58
122.51 122.51 mirror 122.51
total 169.09
Obviously, there are many more combinations possible and my example
may not meet your requirements.
