** Description changed:
When resizing a volume, cinder will notify nova that a volume has
changed its size. For iSCSI attached volumes (ie: Dell Unity), the
package lsscsi is required for that to work. Without it, you get this
error:

Running:
sudo apt install lsscsi
on the compute node fixes this issue.
Steps to reproduce:
openstack volume create --type my-iscsi-volume-type --size 10 test-resize
- openstack server add volume fed31 test-volume
+ openstack server add volume test-server test-resize
openstack volume set --size 20 test-resize
Check the logs on the compute node where the instance is running. There
should be an entry similar to the above snippet.
Check volume size on instance using parted or fdisk. It should be the
same size as before.
