Drive failure, but which one?

[MrKravin]

Greetings,

We were having trouble getting into our GUI a while back, which I finally managed to come up with a work around. To my surprise(horror) I'm getting an alert saying one of our drives is unreachable:

WARNING: The volume storage (ZFS) status is UNKNOWN: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state.Attach the missing device and online it using 'zpool online'.

Here's the zpool status -v reults:

Performing an offline / online results in this:

warning: device '3462125482123835819' onlined, but remains in faulted state
use 'zpool replace' to replace devices that are no longer present

So, I basically figure I need to replace one of my drives. I just can't tell which one it is. I tried mixing them all up to see if it would change order in the status list, but it remains #5. I took all of the drives off of the row that I would think #5 would be, but it still shows as being unavailable.

So is there a way to tell which physical drive has failed?

The OP asked the same question, just 3 days ago.

Thank you, I must have skimmed over that post in my panic. I was able to identify what drive is defective, and I am currently following this guide on how to replace the drive:

http://doc.freenas.org/index.php/Volumes#Replacing_a_Failed_Drive_or_Zil_Device

I am running into a problem, however. When I Offline the drive, and try to replace it, it doesn't allow me to select the replacement drive. Another curious issue, is when I click Replace, it says "Replacing Disk ", with no drive identification.

Can't provide any advice. Maybe delete any partition tables on the replacement drive or zero it out. I've done those exact steps recently and I can vouch that they work perfectly if you follow them in order.
