Hi all,

I was wondering if one of you good people could assist me with a problem I have.

I have a zpool which consists of two 146GB disks as follows:

root@server # zpool status zeepool
pool: zeepool state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
zeepool ONLINE 0 0 0
c1t4d0 ONLINE 0 0 0
c1t5d0 ONLINE 0 0 0

errors: No known data errors
root@server #

Basically its just a pool without resilience. I now have available two more 146GB disks and I want to make the above pool resilient. So I can try to use:

root@server # zpool attach zeepool c1t4d0 c1t6d0
root@server # zpool attach zeepool c1t5d0 c1t7d0

But then I get:

root@server # zpool status zeepool
pool: zeepool state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
zeepool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c1t4d0 ONLINE 0 0 0
c1t6d0 ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c1t5d0 ONLINE 0 0 0
c1t7d0 ONLINE 0 0 0


errors: No known data errors
root@server #

What I want to know is: is this the correct/best way to make the pool resilient? And how will it affect the data on the original pool?

Thanks in advance.
