In disc utility intalled a raid mirror set on two external drives. Later, after using the combined drive, I opened disc utility again and selected 'Automatically Rebuild RAID mirror set'. I didn't select that while installing the raid set, but did that afterwards so when I connected one of the drives again, it would automatically update itself.
This option 'Automatically rebuild raid mirrir set' stays selected while in disc utility. However, when I close and later open disc utility again this option is deselected again. Is this normal? Or does this option remain active when selected and is it just that disc utility assumes that I've removed/connected one or more drives in the mean time and giving me the option to select it again manually in order to rebuild the raid mirror?
