I am looking to do something similar to:

http://lime-technology.com/wiki/index.php/Make_unRAID_Trust_the_Parity_Drive,_Avoid_Rebuilding_Parity_Unnecessarily

 

But in 5.0 beta 13, with a drive that is offline.  I had one data drive fail although the files were still available via the parity as expected.  I replaced the drive, tried to do a rebuild, upon the rebuild starting the parity drive started showing errors immediately.  I let it finish nonetheless, and the parity drive showed millions of errors, with virtually no writes to the parity as expected.  Unfortunately now I am getting i/o errors when accessing folders, and no files are visible.  I am hoping to temporarily get the array back in a similar state before replacing the data drive by having it calculate parity on the fly for the "offlined" drive but unfortunately when I boot it up with the drive missing, it won't start the array as it states there are "Too many wrong and/or missing disks!".

 

The parity drive is unexpectedly blue balled.  This is what I want to correct so I can start up with one drive missing.  The other issues I am not concerned about.  I am not sure why, the drive has not been changed (serial numbers still match, it automatically selects the correct drive, and it has never been removed from the computer).  Is there a way to force it to use the current parity and present data drives and start the array so I can copy some of the content?

 

I'm not concerned with fixing the existing hardware (internal connections etc seem fine), just recovering some files and starting fresh.  Since the file is on the parity drive but not on the data drive that was previously off lined (I checked, it looks like it has been offline for about 2-3 weeks), the only copy available would be using the other data drives and the parity.

I am not certain of how it would work in your version. I do know it is NOT the same as in the 4.X series, and many have had issues in the 5.X series.

 

Basically, I do know that you should NOT refresh the browser after typing

/proc/mdcmd invalidslot XX

as it resets the value upon refresh.

You should instead just press the "Start" button.

Updated to 5.0RC8a and used the built-in function within webgui (checkbox when starting array) and copied files off of shares to another set of drives.
