Once in a while , whenever I checked my disk space usage ..
for / it goes up to 90% and left barely 1Gb out of 19Gb..
so whenever I did a yum install <bigthing>
it complain space insufficient..
it was allocated 19Gb for / .. and the rest goes to /home..
19Gb would be doubled of what being needed to do a full package install of CentOS.. as it only require upto 8-9 Gb..
was thinking to re-format this whole thing.. but wait.. may be it just time to do some clean up..
goes into runlevel 3 with
telinit 3
remove all temporary file
rm -rf /tmp/*
rm -rf /var/tmp/*
remove old kernel and kernel-devel
rpm -q kernel
yum remove kernel-<old-version-number>
and recheck the disk usage..
Hmm..
then it freed up to 7-8 Gb..
Seem back to normal.. don’t need to re-format.. Yay~
