In Raid 5, if one of disks is failure, the system can still work continually. Then how do I know which disk is failure? By hardware Raid 5, I can replace the bad disk by plug in a new good disk. How about software Raid 5 in Red Hat 7.3? Could I just plug in the spare and the system will rebuilt the data from the parity bits from the other disks automatically? What are the commands to process it? Where can I find the documentation about recovering software Raid 5 on Red Hat 7.3? Thanks a lot.

Assuming you've only lost one disk then you should be able to plug in the spare and they system should rebuilt the data from the paratiy bits on the other disks.
