====== Log file Handling ======

If a log file is too large and it cannot be deleted, truncate it:

<code>
truncate -s 0 /path/to/logfile
</code>
For larger files this might take some time. The 'trick' is also used by logrotate copytruncate

Hint: it might be possible that

<code>
ls -l logfile
</code>
still shows the wrong size, but a du -h in the folder is correct.

===== Logroate =====

For services that cannot handle new file descriptors (old log file was closed, moved and a new was opened) it is mandatory to use

<code>
copytruncate
</code>
in the logrotate settings for a service! With this setting, the log file is copied to the “backup” and when this is done, the original log file, same descriptor, is truncated to a size of zero.
