To view and list of the usage of each partition in the server :
[root@centos62 ~]# df -h

tmpfs 504M 0 504M 0% /dev/shm
/dev/sda1 485M 48M 412M 11% /boot
df command will displays the total, used, and available free space on all currently mounted filesystems.
To list the size of a specific directory, run the following command :
[root@centos62 ~]# du -sh /root 2.6M /root
du command reports disk usage. It will shows the disk space used by the files and directories in a directory. The -h option makes the output easier to read by user.
