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.

root@RIGHTSTER-NAS:/etc/default# df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 4.0G 3.1G 610M 84% /
tmpfs 10M 4.0K 10M 1% /dev
/dev/md0 4.0G 3.1G 610M 84% /
tmpfs 1.9G 44K 1.9G 1% /dev/shm
tmpfs 1.9G 21M 1.9G 2% /run
tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
tmpfs 1.9G 0 1.9G 0% /media
/dev/md127 28T 9.9T 18T 37% /data
/dev/md127 28T 9.9T 18T 37% /home
/dev/md127 28T 9.9T 18T 37% /apps
/dev/md127 28T 9.9T 18T 37% /var/ftp/syslog
/dev/md127 28T 9.9T 18T 37% /run/nfs4/home


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.

root@RIGHTSTER-NAS:/etc/default# du -k /* --exclude=/data --exclude=/home --exclude=/apps --exclude=/run/sfs4/home --exclude=/dev/shm --exclude=/run --exclude=/sys/fs/cgroup --exclude=/media --max-depth=1 | sort -nr | cut -f2 | xargs -d '\n' du -sh
1.1G /var
503M /usr
116M /opt
67M /frontview
47M /root
36M /lib
7.9M /sbin
7.0M /bin
7.0M /etc
52K /tmp
8.0K /cp_check_md5sums.sh
4.0K /logs
4.0K /lib64
4.0K /homes
48K /dev

    Which version of mysqlr6 do you have installed? I guess you have 1.0.0 installed?

    # dpkg -l | grep mysql


    You should update to 1.0.1. You could do this from the UI or do

    # apt-get update
    # apt-get install mysqlr6
  • This is the output for mysql

    I did the update and I still have ibdata1 in var and still 2Go, so what should I do?
    Thank you.

    You may need to uninstall the apps that use mysql as well as mysqlr6 and then install mysqlr6 then the apps that use mysql again.

    Or manually move the databases onto the data volume and create a symlink.
  • Ok, I will do a symlink because I don't know what apps use mysql (I think all of them), even the system I don't know if he use mysql.
