schedule 'e2fsck' to run on startup, possible?
 

Is it possible to schedule e2fsck to run on startup? since when i try to run it, it says it's dangerous to run it on an actively mounted partition.

Yes and your system should be already configured.

Look at the last value in the /etc/fstab file entry.
An example
/dev/hda / ext3 defaults 1 1

Look at the last digit. Anything >0 will perform a check according to how the filesystem was setup. The value is based on priority with 1 being the highest. See man pages for fstab for more help.

You can change how often using the tune2fs command.
