I've been playing with DP as an alternate to Storage Spaces on my home server (HP N54L) which runs SVR2012. All works well, much better than storage spaces. Over the weekend I kicked off an upgrade to SVR2012 R2. That failed for various reasons so I did a clean install. After the install I was expecting DP to recognise the drives when I created a DrivePool. Instead it showed "Duplication Inconsistent".
If I've read things right, this *should* work, although the doc I referenced noted moving the license key from the old install to the new. I'm still using a trial license(s) at the moment, so they were different between the old and new O/S installs. Was this the reason for the failure?
Anyway, I had to do a bare metal restore on the server and am now -reloading the discs from a nearline backup. It's a good test of my backup strategy! I will however be trying the upgrade again now I understand the hardware compatibility issue that the N54L has with SVR2012 R2. An in-situ upgrade will preserve DP for me I know, but if I have to do a clean install? What steps did I miss over the weekend that caused the new DrivePool not to full recognise the previous underlying drives?
