我通过运行和替换了zpool statusZFS raidz1 池中的一个故障硬盘（SMART 中的错误计数增加，读/写/校验和错误） 。重新同步很快就开始了，但一直给我带来写入错误（请参见下文）。当这些重新同步过程最终完成时，池将保持在 DEGRADED 状态。如果出现错误或重新启动，另一个重新同步过程将自动启动，但可能会出现不同数量的写入错误。zfs offlinezfs replacezpool clear
SMART 显示此新驱动器没有错误。我还尝试了不同的新驱动器（购买了两个替换件）并更换了 SATA 电缆。在重新同步期间，总是会替换此 vdev（使用任一驱动器）并给出写入错误。这让我怀疑 ZFS 池在某种程度上受到了损害，但它继续运行并且zfs send每天晚上都能运行。
排除故障并解决此问题的正确方法是什么（例如，像zfs scrub只有四个驱动器中的三个驱动器的降级池，因为zfs replace无法在没有错误的情况下完成）？我确实有备份，zfs send/receive希望这些备份是好的副本（ZFS 校验和是否收到流？）。
