<br>
we had an issue when our spce has been upgraded to 6.5.4.<br>
At this time our harddisk went out of space.<br>
<br>
We are planning to move our production system to a new machine so I made some investigations where the disk space has gone.<br>
<br>
First I found the mysqld.err file in /var log/mysql/ with a size of 17GB!<br>
<br>
I wondered about the following:<br>

#########################<br>
<br>
The log is full of these InnoDB errors.<br>
<br>
Has anyone an explanation for this and how to fix it / do more investigation?<br>
<br>
Our disk is currently at 91%, is it possible to move the file to another place (scp to our central backup storage) and restart the logging without service interruption?<br>
<br>
Regards<br>
Thomas<br>
