I currently have a domain controller with 4 drive slots. Only two are taken up, and configured in a raid1 array. We are running low on space, so I purchased another drive. The HP Array Configuration Utility is telling me that it can't add the drive because of the Raid1 configuration, then asks me if I want to reconfigure the drives into Raid5. My question is, will this cause any loss of data? Would I have to restore a backup after configuring, or would the data stay intact?
