There are 2 steps to the volume size extension: iscsi --rescan and
virsh blockresize.
As an admin, you could call the same API endpoint to retrigger all of
those steps.
If iscsi --rescan succeeds but virsh blockresize fails, stopping and
starting the instance will fix the issue.
This is the step we asked our customer to perform before virsh
blockresize was added to our implementation.
