There are two metrics used: number of times a FS is mounted and number
of days since last fsck/mount. For machines that don't get rebooted
often (eg servers) the 'number of times a FS is mounted' almost never
kicks in and the 'number of days since last fsck/mount' does.

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.
