Hot swap drives in array

Hello,

I am sure I have seen this request before, but I cannot find it now. Apologies if it is a repeat.

I would like to (somehow) be able to add and swap drives in the array without stopping it. Recognizing that the correct hot swap capable hardware would be required, is there some way that unRAID can allow for a drive to be swapped from or added to the array without stopping the array and thereby stopping all VMs, Dockers, etc. on the server?

Perhaps there could be a GUI option to mark a drive for swap - the array could see it as a "failed" drive and stop attempting to write to it, keeping the data in memory or writing to parity, and then when the new drive is swapped in rebuild the parity onto it.

For adding a new drive, perhaps some sort of "add to array" option could be added next to or in a screen for the new disk. I wouldn't want any new disk plugged into automatically become part of the array, but once the disk is precleared and formatted, it would be great to add it without taking everything down.

Thoughts?
