ZFS数据集在重新引导时消失

我已经在我的Centos 7中安装了ZFS（0.6.5），而且我也创build了一个zpool，除了重启后我的数据集消失之外，一切正常。
我一直试图在各种在线资源和博客的帮助下debugging这个问题，但无法得到预期的结果。
在重新启动后，当我发出zfs list命令时，我得到“没有可用的数据集” ，而zpool list给出了“没有可用的池”在做了大量的在线研究之后，我可以通过使用zpool import手动导入caching文件来使其工作， c cachefile ，但仍然必须在重新启动之前运行zpool set cachefile = / etc / zfs / zpool.cache Pool ，以便稍后在重新启动后导入。

这就是systemctl status zfs-import-cache样子，

zfs-import-cache.service - Import ZFS pools by cache file Loaded: loaded (/usr/lib/systemd/system/zfs-import-cache.service; static) Active: inactive (dead)

cat /etc/sysconfig/zfs

我不确定这是不是一个已知的问题，如果是的话，有没有解决方法？ 也许一个简单的方法来保存我的数据集重新启动后，最好没有caching文件的开销。
