Is it "absolutely" necessary to run this on servers? Especially since they
don't reboot often, but when they do it takes ages for fsck to finish -
which on web servers causes extra unwanted downtime.
Or is there a way to run fsck with the server running? I know it's a bad
idea, but is there any way to run it, without causing too much downtime? I
just had one server run fsck for 2+ hours, which is not really feasible in
our line of business.
