在Solaris 11上导入导出池失败
在Solaris 11上导入导出池失败
提问于 2016-09-11 06:17:14
无法导入导出池。
根据下面的信息，我能以某种方式导入池吗？或者，是否有从驱动器本身检索数据的方法？
这两种磁盘上都没有损坏。
Solaris 11.3
# zpool upgrade -v
This system is currently running ZFS pool version 37.
# zpool import
no pools available to import我试过各种旗子：-a，-d，-f.但仍然不能导入池。
如果我运行# zdb -l /dev/dsk/c2d1，它输出..。

下面的答案是一个解决办法。正确的答案应该说明为什么zpool import没有正确导入池，尽管zbd选择了标签0，但没有正确地“读取”它。
不是所有的东西都丢失了。使用镜像驱动器之一，并将其粘贴到另一台计算机上，即从Solaris 11.3 LiveCD启动(或至少有一个具有类似zfs版本的操作系统版本)。
zpool import media_pool在另一个盒子里是成功的。现在出口。
zpool export media_pool
在原始机器上清除/etc/zfs/zfs.cache。是Poweroff。删除第二个镜像驱动器。插入原始镜像驱动器(从上述步骤导出的驱动器位于不同的框中)。重新启动机器并导入池。
