zfs discuss - Mar 2010 - ZFS RAIDZ Auto Resize?

I thought I had read somewhere that zpools in ZFS will automatically resize
(expand) when larger disks are detected to a point where it is feasible to
expand.  To this end, I have a four-drive zpool using RAIDZ(1).  I upgraded all
four of the drives from 500GB to 1TB, but haven''t seen any expansion of
the pool  Perhaps I misread, or is there something I need to do to get the zpool
to recognize the growth?  If I go into the format command and look at the
drives, they seem to be showing up to Solaris under the new size, so I
don''t think the issue is with the new space not being recognized.

Thanks!
-Nick

Depending on your OS release, the expand may work on next import
or you can set the "autoexpand" property to "on."

Awesome - thank you to all who responded with both the autoexpand and
import/export suggestions!  I will try it out!
