Fsck

Fsck is a program that checks the hard drives for file system consistency. In MEPIS 8, fsck runs after the OS has been booted 100 times.

You can change the time or stagger the drives to be checked by opening a terminal, becoming root and typing:

tune2fs -c <number of boots> /dev/sda<partition number>

So, for instance, to separate out the checks for three partitions, you would enter one at a time

tune2fs -c 98 /dev/sda1
tune2fs -c 99 /dev/sda2
tune2fs -c 100 /dev/sda3

This command stores these parameters in the nominated file system (partition), and is examined by the kernel at boot time hence there is no config file to check your settings however they can be viewed with the -l switch,

tune2fs -l /dev/sdb1 | grep -i mount

Using a pipe to grep outputs the mount info only

Last mounted on:          <not available>
Default mount options:    (none)
Last mount time:          Wed Dec 28 10:22:20 2011
Mount count:              0
Maximum mount count:      92


You can also force a check if you feel the need by using MEPIS System Assistant.
