expanding pool but "no such device in pool"

[alobi]

Hi
I am still new in using ZFS on my Mac, but it runs fine since some month.
I had a pool with 3 x 2TB and need more space. So I get three 4TB devices and changed one after the other with "replace".
That works fine so far, but it doesn't expand the capacity. So I want to try some hinds from the forum, but always end up with the line

Code: Select all

no such device in pool

Here what I had done. First the status:

Code: Select all

zpool status tank
  pool: tank
 state: ONLINE
  scan: resilvered 1,73T in 14h0m with 0 errors on Sat Aug 27 03:01:39 2016
config:

   tank                                            ONLINE       0     0     0

errors: No known data errors

So I try to take one out with

Code: Select all

sudo zpool offline tank media-1C201D55-D215-0D44-AA4F-0E47BCFBCB01

but

Code: Select all

cannot offline media-1C201D55-D215-0D44-AA4F-0E47BCFBCB01: no such device in pool

OK. Than I try it with the device name from diskutil, but it makes no difference if I take disk1 or disk1s1, which is the device, always:

Code: Select all

no such device in pool

I have tried some other thinks, but to go on I have to solve this first, I think

I think you need to use the device GUID, which you can obtain via "zpool status -g"

Then I think you "zpool online -e guid" for each disk.

Have you set the pool attribute "auto expand" to ON?
