/dev/mapper/centos-root is 100% full

smarthosting
My /dev/mapper/centos-root is mapped to / and is 99% full. This is causing issues with services crashing and the server becoming unstable. However, I am not sure why this keeps happening. /home is far from full, where all user data is stored. df -h [root@s2 ~]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 12G 0 12G 0% /dev tmpfs 12G 0 12G 0% /dev/shm tmpfs 12G 1.2G 11G 10% /run tmpfs 12G 0 12G 0% /sys/fs/cgroup /dev/mapper/centos_s22-root 50G 50G 929M 99% / none 12G 6.5M 12G 1% /var/lve/dbgovernor-shm /dev/sdb1 234G 194G 28G 88% /home5 /dev/sda2 1014M 178M 837M 18% /boot /dev/sda1 200M 9.8M 190M 5% /boot/efi /dev/mapper/centos_s22-home 413G 375G 39G 91% /home /dev/loop0 2.2G 11M 2.1G 1% /tmp tmpfs 2.4G 0 2.4G 0% /run/user/0 du -sch * --exclude=home [root@s2 ~]# du -sch * --exclude=home 4.0K anaconda-ks.cfg 48K cldeploy 24K cloudlinux_ea3_to_ea4 276K cpanel3-skel 3.0M cptechs 436K error_log 4.0K install.log 8.0K install.sh 4.0K legacy_ea3_distiller_files-1573085122.tar.gz 4.0M maldetect-1.6.4 1.5M maldetect-current.tar.gz 8.0K mysql-community-release-el7-5.noarch.rpm 4.0K pclzip-5cc80afed42a9.gz 0 perl5 4.3M tmp 0 version.dat.old 14M total

    Hey there! / contains all data that isn't inside of another partition. Looking at your specific output, this would include areas like /usr, /var, /root, and other areas of the system outside of /home. I like to use "du -h --max-depth 1" starting from /, and then working my way down through the directories until I find things I can remove.
