Kebetulan mendapatkan kesempatan fixing aplikasi Rails milik client yang down. Web servernya menggunakan apache dan passenger. Saya cek lognya ternyata kehabisan space SSD. kemudian saya coba mencarinya file-file dengan ukuran besar(diatas 100MB) dengan perintah:

sudo find / -type f -size +100M -exec ls -lh {} \;

ternyata error.log milik apache2 berukuran 7 Giga lebih. Hindari menghapus dengan perintah rm karena file tersebut akan di lock oleh apache2, saya menggunakan command:

$ env | grep rvm

uninstall: Here is a custom script which we name as 'cleanout-rvm'. While you can definitely use 'rvm implode' as a regular user or 'rvmsudo rvm implode' for a system wide install, this script is useful as it steps completely outside of RVM and cleans out RVM without using RVM itself, leaving no traces.

#!/bin/bash
/usr/bin/sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh /usr/local/rvm /usr/local/bin/rvm
/usr/bin/sudo /usr/sbin/groupdel rvm
/bin/echo "RVM is removed. Please check all .bashrc|.bash_profile|.profile|.zshrc for RVM source lines and delete
or comment out if this was a Per-User installation."
