Version-Release number of selected component (if applicable):
OSP13

How reproducible:
always

Steps to Reproduce:
1. migrate from 10 to 13
2. spawn instances
3.

Actual results:
computes with the specified disk not found error are removed from the scheduler

Expected results:
computes not removed from the scheduler
