Cannot logon to plesk Linux

[GarabedY]

I tried access my plesk box via http://ipaddress:8443 but am met with an web page not available error. I checked my disk df -h and found

/dev/mapper/VolGroup00-LogVol00 Use% is at 100%. What can I clear out to get it up and running again?

Just remove all unnecessary files and then restart psa service with

# /etc/init.d/psa stop
# /etc/init.d/psa start

What files can I safely remove?

I would like to know what files I can delete from plesk to get some disk space back and have the ability to get back into the system again?

What files can I safely remove?

I suppose any non-system files. Like video, pictures, mp3, distribution kits, archives, etc.
