今天，我不得不拆卸并重建一个服务器风扇来修复它。启动服务器后，我遇到了一个问题，即所有磁盘都不在它们昨天所在的位置。因此系统无法安装我的阵列。现在所有磁盘都具有与以前相同的旧路径...但我的系统无法在启动时安装它们，并显示错误“无法读取超级块”，我对 raid 配置不太熟悉。这就是为什么我总是害怕运行错误的命令并擦除所有磁盘。
这就是我要问的原因，将超级块清零并重新创建“新的” raid5 阵列是否安全？

对我来说，dmesg 的错误似乎是我的 pi 电源有问题。我有一个带 Rock-Pi SATA 头的 Allnet NAS。它将通过 USB-C 由 45W 电源供电。HDD 本身通过 Raspberry 上的 SATA 和 GPIO 端口连接，但 HDD 还通过 PI4 板到 Rock-Pi SATA 端口的 USB3<->USB3 端口连接连接。我拔掉了它。启动系统，并在启动后重新添加 USB3 端口。此后，dmesg 没有显示读取错误。它似乎很好，因为什么都没有发生......真的很奇怪。
答案1
有一个几乎相同的问题和帖子https://superuser.com/a/811116/250231
在开始之前验证要使用哪些驱动器，要么全部使用，要么使用一个缺失的驱动器以便稍后重建。最后，--assemble --force重要的是确保顺序正确。
根据最新--examine数据，您应该能够：
mdadm --stop /dev/md127
mdadm --assemble --force /dev/md127 /dev/sd[abcd]
cat /proc/mdstat
a和可能首先断开连接，并且该信息在和b更新，所以这就是您遇到此问题的原因。我再一次强调，您应该尝试了解它们断开连接的原因，并且日志显示了这一点，如果驱动器断开连接，请在重新启动之前获取该数据。（可能是电源或连接器不稳定。）cddmesg
如果您准备丢失数据，则只能使用零超级块。
答案2
将所有磁盘恢复正常状态后，我组装并检查了 dmesg。我该如何继续？
