ja_sen Posted April 16, 2015 Share Posted April 16, 2015 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! Link to comment
switchman Posted April 16, 2015 Share Posted April 16, 2015 As your starting over, I would only do the new drive to stress it. Link to comment
garycase Posted April 17, 2015 Share Posted April 17, 2015 You don't HAVE to run pre-clear on any drives. If you have new drives you want to test with pre-clear before creating the array, do that first. Once you're ready to build the actual array; just do a New Config; assign your drives as you want [4 data drives, parity, and cache]; set the desired file system (v6 defaults to XFS); and then Start the array. Check the Format button if there are any unformatted drives [if they were previously Reiser and you've select XFS this will be necessary]. After you Start the array, it will do a parity sync. When that finishes, run a Parity Check to confirm all is well. Done :-) Note: If any of the drives already had the correct file system and you didn't clear them again, they will still have any previous data on them => simply delete those files after everything is otherwise ready.
