What is the proper way to remove a disk from FreeNAS?

[Chris Dawalt]

I just added a 4TB NAS disk to my system and would like to remove an old 160GB disk that I don't use. Plus I am out of physical hard drive mounting space, so this will open a spot. What is the proper way to remove the 160GB from the FreeNAS system?

It depends upon the vdev layout. Post the output of zpool status.

 

[Chris Dawalt]

Can this (zpool status) information be obtained through the web GUI? The motherboard is buried within a case that I can't easily access if I need to get to the console. (no monitor attached)

I should add that there is no data that I need to save on the disk that I wish to remove.

 

[dlavigne]

Yup. click the shell icon and type that command (zpool status).

Here you go - and G is what I want to remove...

Am I reading this right? Each disk is in its own pool?

 

[Chris Dawalt]

Yes - I use my FreeNAS as backup storage, and I have a duplicate of each FreeNAS hard drive in my main (Windows) system. Every week or two I create images of each of my 4 systems (wife's computer, son's computer, etc) and keep a copy in two places. Maybe not the best / smartest way to do it, but it works for me. I am certainly open to suggestions. I started using the FreeNAS as more of a trial on some old hardware I had - just to see if I could make it work. Well, two years later it continues to perform flawlessly, despite my non-kosher hardware choices and likely improper disk setup. But that is why I keep my backups in two places.

Right there in front of me! Sheesh, I must be blind!

I have a similar setup Chris, very old hardware re-purposed for FreeNas. And yes, I don't trust it much so I plan on duplicating as much as possible just to be safe.

And as cheap as hard drives are now... I just got two 4TB Seagate NAS drives for $119 each.

In this case where you have a single drive backing a dataset, just detach and destroy the dataset. Poof data is gone.

Ah, yes - I was actually just reading about the Detach function in the FreeNAS documentation. Thanks for confirming...
