由于缺少一个设备，ZFS 池消失并显示“I/O 错误”

我有一个名为 3 个磁盘的 ZFS 池data。两个磁盘通过 ID 连接到 raidz，但第三个磁盘通过卷 ( sda) 连接。我物理移除了 sda 设备，因为我想通过名称连接它。但是当我重新启动时，该池不再可用。

两个磁盘 ID 驱动器仍显示为 ONLINE，但无法导入池并显示“无法导入‘数据’：I/O 错误”

我正在运行 Ubuntu Server。

命令输出：

请帮我！

从错误消息来看，您似乎在另一台机器上安装（或尝试导入）了该池。您确定没有其他物理机或虚拟机尝试导入该池吗？

如果您确定没有其他机器尝试导入该池，请删除缓存文件并尝试强制导入：

rm -f /etc/zfs/zpool.cache; zpool import -f data
