<br>
We have a development box with local storage, running ovirt Node 4.1<br>
<br>
It appears that using the admin interface on port 9090 I can resize a live partition to a smaller size.<br>
<br>
Our storage is a seperate LVM partition, ext4 formated.<br>
<br>
My question is, both theoretically and practically, if anyone has feedback on:<br>
<br>
<br>
#1: Does this work (ie- will it shrink the filesystem then shrink the LV)?<br>
<br>
#2: May we do this with VMs running?<br>
<br>
<br>
Thanks<br>
