@Cata_Lin Welcome to the Rockstor community.

This error is caused by your system disk having no serial number. Look to your hyper visor / Virtual machine configuration and make sure that you have a unique serial for each device. All real (non VM) drives have serial numbers and Rockstor uses these to track the drives. This is a recent inelegance introduced by me I’m afraid and I intend to improve the error messaging once I’m done with my current issues.

We do have a doc issue open to address this requirement:

Hope that helps.
