I have a question in regards a new config.

I currently have a 6TB drive on disk 2 which I need to use for another project. I had a smaller driver that I wasnt using so was going to replace disk 2 from a 6TB to a 4TB driver. As we know this will not work as you cant go smaller. So the idea I have is temporarily add the 4TB drive to the array and copy everything from disk 2 to disk 8. So now my question is if I create a new config and start by reducing the drives used by one and then remove the 6TB and assign the 4TB to disk 2 the server shouldnt know any different? Yes? I will point out that I want to assign the 4TB to disk 2 because I have alot of dockers that point to disk 2 and I think this is easier that reconfigure every docker.

You have to rebuild both parity if you add or remove disks with New Config, and it will by default.

Thanks for the heads up, I thought that may be the case. But rebuilding the parity aside, my plan should work yes?

Tools - New Config, Retain All, Apply

 

Change assignments as needed before starting the array. Don't check box saying parity is valid.

 

Be sure you don't assign any data disk to any parity slot.

 

Start array to begin parity rebuild.
