trouble replacing Disk RaidZ2

[rwps]

I have a non-hotswap HP n36L running Nas4free 9.1.0.1 - Sandstorm (revision 636).
One of the 4 x 2tb disks starting showing errors, so I'm trying to replace it with a new 3tb disk.
However I can't find the right command to get the disk online & resilvering.

I'm entering commands in the gui at ADVANCED/COMMAND, then executing from there.

Disks|ZFS|Pools|Information is currently showing:

Code: Select all

  pool: ourdata
 state: DEGRADED
status: One or more devices could not be opened.  Sufficient replicas exist for
	the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

I have tried many commands, but none are doing anything:
zpool replace ourdata ada3p2 ada3p2
zpool replace ourdata ada3p2
zpool replace ourdata 10974645521217784628 /dev/ada3p2
zpool replace ourdata /dev/ada3p2/ dev/ada3p2
zpool replace ourdata 10974645521217784628
zpool replace ourdata 10974645521217784628 ada3p2
zpool replace ourdata ada3p2 10974645521217784628

I did a scrub and then tried again, no luck
I onlined the disk, and tried again, no luck.

Any thoughts on what I should be doing?

well if its a new 3tb drive there is no ada3p2.

why did you use partitions in the first place?

the command would be
zpool replace ourdata 10974645521217784628 ada3

Thanks!! resilvering now.

Not sure why I have partitions....
Is it something I should address?

[b0ssman]

its just one more thing that can fail.

but its not necessary to change it.

OK, will take note to ensure I don't replicate it in future.
Many thanks
