我制作了一个带有 8x8TB 驱动器的 raid10，其上的文件系统是 XFS。我从未遇到过任何问题。该 raid 配置为 near2 和内部位图。驱动器以 HBA 模式连接到 LSI-9211-8i。
上周，我终于买了另一套 8x8TB 硬盘，因为磁盘阵列已满。以下是我将其添加到现有 RAID 的方法：
- 使用 smartctl 测试驱动器（没有问题）。
- 在每个驱动器上创建了一个新的 GPT 分区选项卡和一个 XFS 分区。
- 使用命令
sudo mdadm /dev/md0 --add /dev/...添加驱动器。 - 通过执行来扩大阵列
sudo mdadm --grow /dev/md0 --size=max。首先花了 2 天时间进行重塑，然后花了一天时间进行重新同步。一切顺利，没有任何错误或中断。之后，突袭变得干净且活跃。 - 使用 调整文件系统大小
sudo xfs_grow /dev/md0。它顺利完成。 - 安装 RAID 阵列并进行测试。它运行良好。我重新启动了服务器以确保阵列仍然干净。
那么发生了什么？！我使用阵列通过 Radarr、Sonarr、Deluge（全部在 docker 中）下载新内容。我不得不重启服务器（我每周重启一次以释放资源），然后发生了一些事情。
raid 阵列现在处于非活动状态（请查看下面的 mdadm 详细信息）。16 个驱动器中有 4 个的事件计数错误。经过多次尝试，我通过执行 成功恢复sudo mdadm --assemble /dev/md0 /dev/sd[...]。我使用 测试了 XFS 文件系统sudo xfs_repair -n /dev/md0，pfiou... 一切似乎都正常。
出于好奇，我今天尝试再次重启，确保 Docker 容器已关闭。我检查了阵列是否干净，因此我等待了 5 分钟，然后我做到了sudo reboot。同样的事情再次发生！！这次 6 个驱动器的事件计数不同步...所以我再次执行了与上述相同的操作，看起来不错，但现在我非常担心，因为我目前没有任何证据可以支持这一点（我知道这很糟糕）。
你们知道发生了什么吗？提前感谢你们的帮助！:)
sudo mdadm --examine...在我重新组装之前：
