Well I figured it out. To add a new drive to the system the drive must be blank. The error message threw me off. There is no issue with the software but it would have been nice for a hint. I pulled up the cli and ran part to remove my test partitions on the drive. The system GUI recognized the drive and let me add it to my existing BRTFS pool. I am not new to Linux but I am new to this OS. A rookie would struggle with this condition. Why did the error box show up was it (user error) or a bug in the program needs to have a little more explanation.

Glad it worked for you. You are right, that this not entirely self-evident that the drive state itself might be the cause vs. another reason. We have a brief reference to that in the pre-install best practices:

https://rockstor.com/docs/installation/pre-install-howto.html#wiping-disks

but that is not obvious information for someone that installed Rockstor successfully and then wants to add a new disk, and this scan failure is also dependent on what the disk might have been filled with before (Linux FS vs Windows, data disk vs. OS disk). May be a brief new section for adding new disks could be helpful in the documentation. Eventually, this could also be a tooltip on the WebUI.

If you’re up for it, you could submit a proposal for documentation here:

Thanks for pointing this out.
