Root 100% Full But Cannot Find Files to Delete in Root
After a period of power outages (called Loadshedding), my ReadyNAS has started mailing me warnings: System volume root's usage is 100%.
Accesssing the NAS via SSH does not appear to help me as there is nothing that I can see to delete from the root folder.
#df -i gives me:

I have looked at other posts but I am nervous to run the "balancing" commands if I do not know what the potential pitfalls are.
Thank you in advance for your assistance.

Hi Asimb

Hi Jonbooi
Yea, these small files that you removed aren't gotta cut it :)
You can remove the daily.cld and main.cld files as well. You should also turn off AV as that will be removed from the RN102 in the next firmware anyway. But this is not all that is taking space on the root volume. When those files are deleted, what does this command give you?
du -hd1 /var
I also deleted the daily.cld and that has allowed me to reconnect to my NAS again.
I will monitor and see if that has sorted the problem.
I will also leave the antivrius deactivated from now on.
Thank you all.
