when using at least two compute nodes, and use NFS share_storage to test resize an instance.
The configuration of NFS used the introduction about live-migration using NFS in community doc.

when executed command "nova resize ae6f9472-3080-4e86-8a52-f8e642081d15", can work well, and the instance's state will change to "VERIFY_RESIZE', Then I resize-confirm it, nova met the issue as follow:
