Subject KVM Ceph libvirt online resize
Date Mon, 03 Apr 2017 09:33:10 GMT

currently we are testing 4.9.2 with KVM and Ceph. Online resize of volumes via API and UI
is possible but the guest does not recognize a resize was done.

It's possible to "notify" the guest by triggering the following command from the KVM host:

virsh qemu-monitor-command --hmp i-168-4502-VM 'block_resize drive-virtio-disk1 125G'

But there must be a method to trigger something from within the guest VM?

All the best,
