Ubuntu和ZFS在重新启动时会丢失池

我正在使用Ubuntu 12.04 LTS的全新安装以及ZFS PPA 。

我发现当我创build一个池，它会挂载和运行正常，但重新启动后，它显示为UNAVAIL，我找不到一个方法把它拿回来。

这里是一个快速testing的日志来演示：

• Nexenta，NFS和LOCK_EX
• Solaris 10 x86 – 试图replacezpool中的磁盘
• ZFS / ZFS发送数据库复制
• ZFS热备份限制写入速度？
• 禁用ZFSonLinux上的caching

按要求输出ls -l /dev/disk/by-id/scsi-* ：

我刚刚做了一些进一步的testing。 而不是使用ID我试着用sdb，sdc等：

 zpool create data sdb sdc sdd sde 

同样的结果。 它创build了池，但重新启动后，它是“UNAVAIL”。

根据要求，输出zdb -l /dev/sdb ：

 ~# zdb -l /dev/sdb -------------------------------------------- LABEL 0 -------------------------------------------- failed to unpack label 0 -------------------------------------------- LABEL 1 -------------------------------------------- failed to unpack label 1 -------------------------------------------- LABEL 2 -------------------------------------------- failed to unpack label 2 -------------------------------------------- LABEL 3 -------------------------------------------- failed to unpack label 3 

在创build一个新的池之后，我做了这个testing，得到了相同的结果。

我刚刚尝试了Ubuntu 11.04的全新安装（以排除12.04版本中的错误）。

1. 添加了PPA存储库
2. 做了dist-upgrade，然后安装了ubuntu-zfs
3. Ran'zpool创build数据sdb sdc'
4. 检查zpool状态并在那里显示池
5. 重新启动服务器
6. 再次检查，仍然在那里。

所以这是我的12.04事件的一个问题。 诱惑只是重新安装…

 cd /path_to_your_disks zpool import -d . <name_of_your_pool>
