Problem Description:

When attempting to create a ZFS RAIDZ pool, I get the following message:

[CODE]
cannot create 'tank': one or more devices is currently unavailable
[/CODE]


Command used to make this occur:

[CODE]
zpool create tank raidz label/P1SG136D.eli label/P2SGY10S.eli
label/P3SG3ERV.eli label/P4SGC4QY.eli label/P5SGYJSC.eli
label/P6SG49JV.eli label/P7SG9H9H.eli label/P8SGDF8G.eli
[/CODE]


System:

Asus M3N WS
Athlon II X2 240
8gb Kingston DDR2 ECC
8 X 1.5tb Seagate SATA drives
60gb IDE drive
HighPoint RocketRAID 2220 PCI-X
PCI RivaTNT

Overview of What I've Done:

Reading #1 was used as a rough guideline to make a ZFS pool with geli
encryption.   I used Reading #4 & #5 to label my drives.  I believe
one should be able to create an encrypted ZFS pool using labels due to
Reading #2.  The commands from Reading #1 were slightly modified with
help from Reading #3.


Code:

[CODE]
glabel label -v P1SG136D /dev/da0
glabel label -v P2SGY10S /dev/da1
...
[/CODE]


This labels each drive attached to my HighPoint controller with the
Port # it is attached to, the company brand, and part of the serial
number so that I can easily identify which drive has a problem in the
future.


[CODE]
dd if=/dev/random of=/usr/home/THEJEW/P1SG136D.key bs=64 count=1
dd if=/dev/random of=/usr/home/THEJEW/P2SGY10S.key bs=64 count=1
...
[/CODE]

Encryption keys are created and placed within my home folder.  Home
directory is also encrypted, but passphrase is entered at boot (ie.
keys are available).


[CODE]
geli init -a HMAC/SHA256 -e AES -l 256 -s 4096 -K
/usr/home/THEJEW/P1SG136D.key /dev/label/P1SG136D
geli init -a HMAC/SHA256 -e AES -l 256 -s 4096 -K
/usr/home/THEJEW/P2SGY10S.key /dev/label/P2SGY10S
...

[/CODE]

Preparing to attach key to label to create *.eli in "label" folder.
*.eli files do appear in Dolphin.


[CODE]
geli attach -k /usr/home/THEJEW/P1SG136D.key /dev/label/P1SG136D
geli attach -k /usr/home/THEJEW/P2SGY10S.key /dev/label/P2SGY10S
...
[/CODE]

Attaching.


Attempting to create zpool fails (see code in Problem section).
Everything attempted as root.



Any help appreciated.
