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

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
