Hi I am replacing a smaller data drive with a larger drive.  I have installed the drive and removed the smaller drive and am running pre clear my question is do I need to reconnect the smaller drive and Unassign it or can I just add the larger drive once pre clear is complete.

 

 

Thanks

You should just be able to

• stop the array
  
• assign the replacement drive
  
• start the array to do the rebuild
  

 

Having said that it would not do any damage to

• stop the array
  
• unassign the old drive
  
• start the array with the drive missing (so it is being emulated)
  
• stop the array again
  
• assign the drive to be used
  
• start the array to start the rebuild
  

The reason you sometimes want to go through these extra steps is that it causes unRAID to forget the old assignment so that you can (if needed) rebuild the drive back onto itself.  Doing these steps when not necessary does no damage and it is not a bad habit to get into and it only takes a few extra seconds to do them.

Thank you there is nothing on the smaller drive that's why I just took it out but just wanted to make sure not unassign it would not cause problems

Even though the smaller drive has no files, its empty filesystem is still part of parity. While it is missing, and until it is rebuilt to the larger drive, your other drives are not protected.
