Even with a hot standby you do not want your redundancy offline just because it uses the hack that is fsck. There is no real reason to hold the computer offline for the time an fsck takes when there are alternatives.
The argument about using ups solving every problem is also flawed. I have seen a careless move (man accidentally leaning agains the emergency power-off of the computer hall) shut down a ha cluster that was fortunatly and ironically only used for testing stability. As long as there are people designing and running the computers there will be errors made which must be recovered from as fast as possible.
