[ovirt-users] oVirt Node Resize tool for local storage

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