zfs discuss - Sep 2009 - Expanding RAIDZ with larger disks - can''t see all space.

Posting this question again as I originally tagged it onto the end of a series
of longwinded posts of mine where I was having problems replacing a drive. After
dodgy cabling and a few power cuts, I finally got the new drive resilvered.

Before this final replace, I had 3 x 1TB & 1 x 750GB drives in RAIDZ1 zpool.

After the replace, all four are 1TB, but I can still only see a total of 2.73TB
in zpool list.

I have tried:
1. Reboot.
2. zpool export, then a zpool import.
3. zpool export, reboot, zpool import.

However, I can still only see 2.73TB total. Any ideas what it could be?
All four disks show as 931.51GB in format. Where should I start troubleshooting
to see why ZFS isn''t using all of this space?
I''m currently on SXCE119. I tried a mock-scenario in VMware using the
2009.06 live cd, which worked correctly after an export and import.
Can''t do this on my setup, however, as I have upgraded my zpool to the
latest version, and it can''t be read using the CD now.

Thanks,
Chris

zpool set autoexpand=on poolname

I knew it would be something simple!!  :-)

Now 3.63TB, as expected, and no need to export and import either! Thanks
Richard, that''s done the trick.

Where is the original post?  I was wondering what the steps would be to replace
with larger drives.

Thanks,
Greg
