Here is the short version of my story...
I created an unRAID box that I made several mistakes in creating (file structure, to many shares, installing plugins wrong, etc.). I want to erase all of the data, upgrade to 6.X and start from scratch. I currently have a 3TB parity, 1 TB cache and 3 data drives (3TB, 3TB, and 2TB). I want to upgrade the parity to a 4TB move the 3TB (old_ parity) to the array and replace the 2TB with a 3TB (being 4TB parity, 1TB cache and 3TBx4 in the array).
What is the best way to finish everything here? Do I need to rerun the Pre_Clear on all drives or only the new ones?
Thanks for the help/wisdom!
