Root partition full and can't account for all 4GB
I am trying to figure out how the 3.1G of the 4G root partition is being used. I'm at 84% right now but it's been as high as 98% and don't want to run into that situation again.
I can't figure out where all that disk space is being used at. When I look at the du excluding the other mount points I can only see about 1.8G of usage.

# du -csh /var/log/frontview/*- thanks for those list of commands. I noticed a few were reporting on the log locations and that's where Netgear support cleaned up some files but it was only a few MB worth and brought down the 98% to 84%.
Here's the output...root@RIGHTSTER-NAS:/etc/default# lsof | grep deleted

Why have you got one or more large MySQL databases stored on the OS partition? mdgm wrote: Oops the service may be called mysql

Ran the restart, I should have realised that it was mysql. Still at 93% used now.
Not sure what the db is doing there. Here's the list of them below. But all this still is accountable for in terms of the space. I can't account for all the space being used to try and free up any more space.

Perhaps try restarting apache2 as well. - Same happened to me.
Without actively using the mysql database, it keeps growing without Limits - and is eating up the root Partition.
When I tried to uninstall some apps via the GUI, I ended up with no GUI!
Luckily I had enabled SSH so I could still log in and get things fixed.
My conclusion is that mysql should NOT be used and that it should be disabled.
Will copy all my data to a second RN 516 (I am a lucky man) and then to a fresh install of my first RN 516 which encountered the "root partion 81% full"
- Max - The MySQL version in my Dropbox relocate data in /apps so /var will not be full
Envoyé de mon iPhone en utilisant Tapatalk - Hi,
I have the same problem, root partition is full. I did a clean and a balance but still 88% using.
When I look into it I see file /var/lib/mysql/ibdata1 is more than 2Go. So if I use the MySQL version in super-poussin Dropbox it will relocate data?
Also /var/ftp/ "regroup" all my data, it's a symlink? Ftp service is disable so why he keep a trace here? Maybe it's the source of the problem.
I have plex, sickbeard, sabnzbd, transmission and pyload installed.
Thank you
