Well first clear out your Disk a bit .., i can see /dev/md2 is 100% used.

If you need further help, Please feel free to contact us via our website or drop an email to sales[at]serverpolice.org
 
use command du to find what takes that much space:
cd /
du -sh ./*
then go to folder with big size and etc etc:
cd /var

du -sh ./*

Then you will found out what takes that much space.
