[Webmin+virtualmin] Change /home to other partition

Virtualmin
1

I am pretty new to linux/virtualmin/webmin/tomcat.

I have setup a new webserver which currently hosts 5-10 websites.

Setup:

Webmin

Virtualmin

Apache

Mysql

Tomcat

Now one of my websites has uploaded so much data, that the default homefolder location(/home) has used 100% of the available space.

More info:

/dev/mapper/vol_data-lv_var_log 1459032 195272 1190648 15% /var/log

I want to move /home to:
/dev/mapper/vol_data-lv_var

How can I do that, and how can I make sure that all the websites keep running correctly?

Please help!

Easiest would be (including a bit of downtime): Make a new filesystem on the destination device, mount that as e.g. /home2, shut down Apache, MySQL and other servers that might change data, copy everything from /home to /home2 (e.g. using rsync -Phax), then change the mountpoint for /home to the new device in /etc/fstab. Re-mount /home, and done.

Virtualmin doesn’t really care on which device /home is, as long as the mountpoint doesn’t change.
