v10 upgrade - partitions vs. volumes

I suppose you could keep the standard partitions and install 10 on the second slot. Once you're confident in the 10.x installation, you could wipe the disk and use LVM.

 

This is exactly what I had envisioned. Our organization has a very short change window, so if the upgrade goes badly, I would like the ability to simply boot back into my 9.x config because I won't have much time to troubleshoot. This seems less risky to me then wiping the entire disk clean AND installing a major upgrade at the same time.

 

 

On the other hand if I retain the 9.x partition scheme, I will incur another outage when I eventually do convert to LVM. And not only that, I will still have to wipe the disk clean for that conversion. I just won't have the additional risk of performing the upgrade at the same time.

 

 

Can 9.x install on LVM? Is there a process is to revert back to my 9.x config after I have converted to LVM?

 

 

And regarding ntwrkurwrld's comment:

 

When I did the upgrade, it got rid of all of the other partitions using the command above. Now I only have one partion with Version 10 on it.

 

Does that surprise anyone? Can you still use switchboot to view the available partitions, and how do you go about creating additional partitions?
