Consider for example ZFS on Linux gets corrupted on export. This is not a duplicate of meta What do we do about abandoned questions, with a correct answer never accepted?, because this is about questions without a correct answer.
A valid question is initially asked (this particular one has even been protected), possibly one or more answers are provided, but no answer that solves the OP's problem. Eventually, the OP says that for one reason or another, the issue is no longer relevant and possibly the opportunity for determining the correctness of an answer no longer exists. Also, the OP has not provided a self-answer (such as is the case in the cited example), or if there exists a self-answer, it does not actually answer the question.
Hence, the question will likely never receive an accepted answer, the incentive to answer at all is low, and the existing answers may provide little or no value to the community.
At that point, how should we handle the question?
