Title:
OSError occours when try to resize-confirm an instance with status
'VERIFY_RESIZE' using NFS bankend (KVM)
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
when using at least two compute nodes using KVM, 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:
