Hi,

I'm finally able to do online resize

>>-c, --set-capacity loopdev 

>>qemu-img resize volume.raw +1G : ok 
>>losetup -c /dev/loopx : ok 

>>>but now, resize2fs is not working inside the container. 
>>>(so it need to be mounted on the host, so not possible with container online) 

The missing part was to expose /dev/xxx inside the container.
(patch are in my last mountoint patches series)



tested with loop device and rbd device, it's working fine
I'll try to send the resize patch next week.

>>-c, --set-capacity loopdev 

qemu-img resize volume.raw +1G : ok 
losetup -c /dev/loopx : ok 

but now, resize2fs is not working inside the container. 
(so it need to be mounted on the host, so not possible with container online) 

I'll try to find some infos about this.

Maybe.

-c, --set-capacity loopdev 
Force the loop driver to reread the size of the file associated with the specified loop device. 

Worth a try?
