My Ubuntu server has stopped due to a lack of disk space. I deleted some log files which has grown huge very quickly. But
df -h still shows I have no space left. When I run
du -sh /* I can see that I should have plenty of disk space left after deleting the logs.
lsof +L1 and it brought up two files:
/var/log/mail.err. These are two logs I had deleted. I restarted apache, postfix and mysql (mysql wont restart because of lack of disk space, it think) but still
df -h shows no space.
