How to set up RAID in El Capitan

Ive just upgraded to El Capitan but when going to Disk Utility to make a raid system it has seemed to have gone!

Does anyone know if it has been removed from Disk Utility or if it has been relocated?

MacBook, Mac OS X (10.4.11)

Hi!

Perfect solution indeed!

But I have a question: does both disks format in these operation?

I need to jbod (concatenate) to extend my system disk, but I don't want to lose data...

Best regards.

Creating a JBOD erases the drives.

Don't do anything that involves formatting with a guaranteed good backup.

Thanks for the helpful answer.

The reason it works is that Option/Command/R is a restore over the internet to the original OS the computer shipped with. This might not work on a computer that is newer - unfortunately.
