@bridgemarkinc Welcome to the Rockstor community forum.
This error is our current inelegance when faced with a system drive without a serial number, such as some VM systems have by default. Rockstor requires as a minimum specification that all drives have a unique serial number as we rely on by-id names which udev can’t itself create without this unique identifier. Were this to be a data drive then we have a nice message explaining the above only on the system drive we fail rather inelegantly with the message you see. There is now a pending pull request to address this in the docs as a prerequisite:

and there are pending changes that will hopefully allow us to display a more friendly and informative message when the same is encountered on the system drive; as we already do on data drives.

Hope that helps.

If you indicate the nature of your VM / hyper visor then there is mostly likely someone on the forum who can help with the required configuration.

Thanks Philip for the info.

It is a Vmware virtual machine sitting on an ESXi host server.



@bridgemarkinc OK. If you search the forum for VMware there are several references for this problem and it’s solution, ie:

where @unomagan reported the following config as working for them:

Hope that helps.

I do have to apologize for this whole thread. It was not my intention to start a thread. First time install I get the error message and it provides me instructions to submit the info of the error. My first approach to any problem is to research out and find the solution. I know first hand that the problem most likely has happened before. My apologizes again and thank you Phillip for your swift response to the situation.

@bridgemarkinc No apologies necessary. The auto thread creation on submitting issue reports helps with support and seeing what’s not working as intended, and gets the eyes of forum members on issues quicker. But with repeat issues like these it can get frustrating, only this issue was a side effect of a large base design alteration and although irritating, is far better than the original problem the changes addressed. In time we should have this one refined into something a little more descriptive / helpful and in keeping than what currently happens.

Your welcome and hopefully your Rockstor experience going forward will be a little smoother.
