Hi AFAIK ext4 is not supporting online shrinking of filesystem, to shrink storage you would need to unmount filesystem, thus it is not possible to do with VM online. On Wed, Mar 28, 2018 at 2:30 AM, Matt Simonsen <matt@khoza.com> wrote:

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
