When your computer boots, the root file system is in ram and the partitions are initially mounted read only. Then, every so many boots, fsck is run and the system is checked.
To do it manually, on your root file system, since everything is mounted there, you need to do the same thing and boot up using a rescue disk and perform repairs with the disk off-line. You don't have the option of unmounting the the root filesystem because you need it to run normally.
