hi all experts...


i have a gentoo server running with postfix mail..... recently i encounter the hdd spacing getting lower and causing the postfix not functioning.

i look the in /var/log/* directory.... there is few file with huge file size

1) /var/log/mail.info --> 4.1GB
2) /var/log/syslog --> 7xxMB
3) /var/log/mail.warm -->2xxMB
4) /var/log/apache2
5) /var/log/auth.log

is it safe to delete the file?s
i deleted before /var/log/mail.log which is about 2GB.... there is no impart to the gentoo and postfix.

this time the /var/log/mail.log is about 2xxMB only which i also deleted just now.... i think it can't last long as the size is only 2xxMB.
i need to know that other files are safe to delete ? any1 delete these files before?

any proper way to reduce of these file size?


Thanks in advance.

No worries. These are just logs. Delete them when you are running out of space.

I would suggest to check if the package "logrotate" is installed. It should zip the logfiles when they reach a certain age or size. Sounds for me that it is missing on your server.

actually not not really know about the linux system....
install by ex-colleague but surprising...... few years already no problem.... accept insufficient disk space...
i read some forum.... it can do a script to purge or delete the file when it reach to certain file size...
as you mention also there is rotate the log file but i not really understand...
however, if the file is safe delete.... i think will manual delete it.

You can use logrotate with compression.

Google for logrotate howto and enable compression. Logs files are highly compressable. You 2GB file can become a mere 200mb.

In addition to the logrotation you can also adjust your syslog configuration to reduce the amount of stuff being logged. If you don't find a lot of information messages useful you can just cut down logging to errors only. No need to fill up the disk and rotate junk you don't need.

don't delete it.

when you delete this file, you will need to recreate it back.

just empty it, ( # > /var/log/mail.info )

your postfix not functioning bcoz the mail.info log file more than 4GB, most linux kernel default build max size for single file is 4GB.
