Hi all,

I have a server that is build on top of an Asus board which is equipped 
with an Areca 1680 HBA. Since ZFS like raw disks, I changed its mode 
from RAID to JBOD in the firmware and rebootet the host.
Now, I do have 16 drives in the chassis and the line out like this:

root@vsm01:~# format
Searching for disks...done

c5t0d0: configured with capacity of 978.00MB

Looked okay for me, so I went ahead an created a zpool containing two 
mirrors like this:

root@vsm01:~# zpool create vsm_pool1_1T mirror c3t2d1 c3t1d6 mirror 
c3t2d0 c3t1d5

This went just fine and the zpool was created like this:

root@vsm01:~# zpool status vsm_pool1_1T
   pool: vsm_pool1_1T
  state: ONLINE
   scan: none requested
config:

         NAME        STATE     READ WRITE CKSUM
         vsm_pool1_1T  ONLINE       0     0     0
           mirror-0  ONLINE       0     0     0
             c3t2d1  ONLINE       0     0     0
             c3t1d6  ONLINE       0     0     0
           mirror-1  ONLINE       0     0     0
             c3t2d0  ONLINE       0     0     0
             c3t1d5  ONLINE       0     0     0

errors: No known data errors

Now, creating another zpool from the remaining 500GB drives failed with 
this weird error:

root@vsm01:~# zpool create vsm_pool2_1T mirror c3t1d4 c3t1d3mirror 
c3t1d2 c3t1d1
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c3t2d1s0 is part of active ZFS pool vsm_pool1_1T. Please see 
zpool(1M).

Anybody has an idea of what is going wrong here. It doesn't seem to 
matter which of the drives I want to use for the new zpool, I am always 
getting this error message - ven when trying only mirror c3t1d4 c3t1d3 
or mirror c3t1d2 c3t1d1 alone.

Thanks,
budy
