I don't think that the error is really about the missing devices. Most likely the real problem is that you are going too far back in history where the data required to import the pool is not present. It's just that there is no special error code to report that condition distinctly, so it gets interpreted as a missing device condition. -F/-X/-T is not guaranteed to work as the old (freed, overwritten) data is not kept indefinitely. -- Andriy Gapon
