You about the role of the RAID, I have a question, if I use the way of hardware, RAID card do disk array, and then began to install the operating system, operating system will be backup down at this time? When I system there is a problem, whether the operating system can automatically switch to the backup?

CodePudding user response:

Feel you didn't understand RAID clearly, hardware RAID on the operating system is transparent, look at you describe is a RAID 1, RAID 1 need two hard disk drive content is consistent, one of the hard disk is broken does not affect the use,
