*Hi Kurt,
Hi Scott,

there's no such property available.
There's no entry in the manpages, too.*


/bash-3.00# zpool set autoexpand=on testpool
cannot set property for 'testpool': invalid property 'autoexpand'/

*Maybe a problem of the zfs version?



Here's my "zpool history"
*

/Verlauf für 'testpool':
2009-08-03.11:14:27 zpool create testpool raidz1 c1t1d0 c1t2d0 c1t3d0

Hi list,

some months ago I spoke with an zfs expert on a Sun Storage event.

He told it's possible to grow a zpool by replacing every single disk with a larger one. After replacing and resilvering all disks of this pool zfs will provide the new size automatically.


Now I found time to check that and I was not able to grow the pool. It's still the same size as before.

Maybe I missed one step? Or this functionality is not implemented yet?

For your info:

I tested this using VMWare and a Solaris 10u6



Any comments or ideas?
Did you "zpool set autoexpand=on <yourpool>"? It's off by default...

Kurt
