Brief description of the problem

System is telling me that the drive is busy even though I have just restarted the machine and there is nothing that should be using the drives.

Detailed step by step instructions to reproduce the problem

I just tried to create a pool with the two hard disks that are available.

@mark4592007 Welcome to the Rockstor community.

Which version of Rockstor are you experiencing this with. Our current recommended version for new installs is 4.0.7-0:

https://rockstor.com/download.html

You can tell the rockstor version running via:

yum info rockstor

Although this does look like something out side of the rockstor package.

Alternatively if the kernel is having a hardware issue ‘sensing’ the drive then it may be busy due to that. Is this otherwise known good hardware. Some more info about the setup may help folks here with ideas as to what’s going wrong.

Hope that helps.
