我正在运行 Ubuntu 18.04.3 和 zfs 0.7.5-1ubuntu16.6。我的一个磁盘坏了，我正在更换它。在过去，这个方法很有效，只需确保坏磁盘处于离线状态，然后输入：
sudo zpool replace storage /dev/disk/by-partlabel/<disk> /dev/sdX
当我尝试使用新磁盘执行同样的事情时，出现以下错误：
cannot label 'sdc': failed to detect device partitions on '/dev/sdc1': 19
磁盘上什么都没有，没有其他分区或任何我能找到的东西。还有人遇到过这种情况吗？
$ sudo zpool status

zfs我注意到的一件事是分区已创建，但运行 zpool replace 命令后文件系统无法读取：
