Raid 5 questions

Hi, I’m very new to linux and I have a few questions. I wish to setup a raid 5 and want to make sure it will work as I plan.

If I setup a raid 5 array and a drive fails, will I be notified?? If so how??

If I reinstall/upgrade the OpenSUSE is it easy to resetup the raid??

Thx Guys,
Wags
