I am planning to upgrade from OMV 2 to OMV 3 with a clean install as recommended. As I understand aufs pooling is no longer supported in OMV 3.0. Instead, I can use mergerfs. Currently, I am using my pool with Snapraid and I plan to use Snapraid after the reinstall. So my questions are:
1) How do I migrate from a Aufs pool to mergerfs. Do I need to do anything before the reinstall?
2) What about my Snapraid configuration? Will the parity disk need to be "rebuild"?
3) I have any additional disk I'd like to add to my pool. What would be the best time in this setup/installation to add it?
Thanks in advance for your help!
