So I had a call from email user that email server was down, apon logging in notice lots red in status.
Mostly 0% HDD space. that will do it.
Server has 40GB and 4 users and biggest inbox is 10GB, and other 3 all tograther under 1GB. So I dont think its the users / email accounts.
I tried a sudo apt-get autoremove but was not enough tmp space to clean up.
Filesystem Size Used Avail Use% Mounted on
udev 479M 4.0K 479M 1% /dev
tmpfs 99M 424K 98M 1% /run
/dev/dm-0 36G 33G 769M 98% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
none 5.0M 0 5.0M 0% /run/lock
none 492M 16K 492M 1% /run/shm
none 100M 0 100M 0% /run/user
/dev/sda1 236M 45M 180M 20% /boot
So i tried to google this and alot people say just find files and remove them but what is dev/dm-0.
I removed some emails and got server going again at 98% hdd space but urgently need a fix.
Ive tried sudo apt-get clean
sudo rm /var/log/*.gz* to clean old logs but still nothing.
I had moved backups to S2 how can I force delete the local backups?
