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 the...
Hi Asimb
I ran your steps but my NAS still seems to have the same problem. The files deleted were realy small. Here is what I got:

Is there anything else to try?
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
Hi Hopchen
Are my log files also a problem?
20K /var/spool
4.8G /var/ftp
487M /var/lib
72M /var/cache
8.0K /var/www
84M /var/backups
4.0K /var/opt
4.0K /var/agentx
4.0K /var/local
44K /var/nuuo
4.0K /var/mail

16K /var/netatalk
9.6M /var/readynasd
581M /var/log
12K /var/tmp
34M /var/cores
6.1G /varYea, you could go a bit deeper to clean out some more. Output of:
du -hd1 /var/log
There are some mount points that might be getting in your way.
So start by entering
mount --bind / /mnt
That mounts sysroot as /mnt.
Then search /mnt.
When you're done with /mnt, you unmount it with
cd / umount /mnt
The cd matters, the umount will fail if you are in a folder of /mnt.
