You will see each of the those phases happen for each filesystem you have.
Typically 4 or 5. If you have a big disk then one of the filesystems will
be large and will take a long time to be checked.
Reboot the machine and leave it alone for a while. The program printing
those messages is called fsck (file system check) and is like DOS's
scandisk (but more thorough). If it can clean up the filesystems then it
will do so automatically and eventually it will boot up to a login prompt
as normal. If it fails to fix the problems then it will drop down to a
single user login prompt.
If that is what is happening then you'll have to come back and ask for more
help because that's a more complex problem. If this is a box you've just
installed and you don't have a lot of Unix experience then reinstalling
might be the best option in that case.
The correct way to shutdown a machine is "shutdown -h now". Run `man
shutdown` for more information on the various options.
Note to others:
`reboot` and `halt` are not the correct commands to run unless you are in
single user mode. Shutdown brings the system down single user first and
does some administrative cleanup, such as running application shutdown
scripts and saving entropy so you don't have to wait for suitable entropy
to accrue on startup. If you just reboot or halt then those things don't
