Adding HDD

[programmer01001]

Hello,

I have one HDD installed in NAS system with ZFS. Some data is already written on that drive.
What I want to do is add a second drive to do a mirror of first one, without loosing data.
How can that be achieved?

Thank you in advance!

Create zfs mirror by adding a drive?

Create zfs mirror by adding a drive?

Thank you Dusan,

I've done every command right, but the attach command throws following "no such device in pool"

What can cause that? :(

Please post output of:
zpool status
glabel status
gpart show

OK, so you need to run:
zpool attach Volume1 /dev/gptid/c0600c49-81d3-11e3-88bd-d4bed99312c8 /dev/gptid/68501d02-890b-11e3-a3f5-a0f3c1019cfc
As you did not paste the data but attached a screenshot I may have mistyped the GUIDs. The first one should be the one from zpool status the second one should be the ada1p2 GPTID from glabel status. To make sure that you got them right just copy & paste them in the shell.

Unfortunately I have the same error. Can it be a bug?

I just tried in in a VM and it worked. Are you sure you aren't mistyping something? Letter O instead of number 0, ...
Can you please copy&paste the output of zpool status and glabel status and the command you are trying to run (instead of attaching screenshots)?

No mistyping, because I'm copying the gptids from following command outputs.

zpool status:


pool: Volume1
state: ONLINE
scan: none requested
config:

NAME STATE READ WRITE CKSUM
Volume1 ONLINE 0 0 0
gptid/c0600c49-81d3-11e3-88bd-d4bed99312c8 ONLINE 0 0 0

errors: No known data errors

Then I'm out of ideas. It workes for me in a virtual machine running FreeNAS 9.2.0. What version are you using?
