Thanks, I managed to find a way to backup all my data on my old array so I can kill it and just add the drives to the new array.
Hopefully next time I need to shrink it will be released and stable, awesome to see the quick feedback.
I trust mdadm software raid way more than any hardware raid.Allows me to build a relatively cheap system and give me all the protection I need. And it's worked awesome switching between 4 different motherboards now, always detects everything no problem, awesome.
And it's nice to be able to do everything live.
Keep it up, Thanks.
