<br>
I always have some topics to make your brain run as fast as light <img src="http://euranova.eu/myoffice/themes/Default/images/emoticons/normal/smile.gif" alt=":)"> :<br>
<br>
- I have a base image of 3Gb of Ubuntu Server<br>
- Depending on the request I add a volatile disk of 15 / 50 / 150 Gb (this to avoid copying 150G each time I deploy a VM)<br>
<br>
But since the root partition is 3G large, some users are making it exploding without using the 15G free.<br>
<br>
I'd like to use the free storage as hosting partition for /var, /usr, /home.<br>
How could I achieve this since the disk volatile and provisioned on the fly at the deployment.<br>
<br>
I'm trying to mv /var etc... in init.sh at startup, but it make the VM to never start (maybe because /var/lock, /var/run aren't accessible)<br>
<br>
I think symlinks are the best way to do this, I might be wrong.<br>
<br>
Please help <img src="http://euranova.eu/myoffice/themes/Default/images/emoticons/normal/smile.gif" alt=":)"><br>
Regards<br>
CyD</span></p>
