linux – ZFS数据集在重新启动时消失

概述我已经在我的Centos 7中安装了ZFS(0.6.5)并且我还创建了一个zpool,除了我的数据集在重新启动时消失这一切之外,一切正常. 我一直试图在各种在线资源和博客的帮助下调试此问题,但无法获得所需的结果.重启后,当我发出zfs list命令时,我得到“没有数据集可用”,zpool list给出“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 -c cach 我已经在我的Centos 7中安装了ZFS(0.6.5)并且我还创建了一个zpool,除了我的数据集在重新启动时消失这一切之外,一切正常.

在做了大量的在线研究之后,我可以通过使用zpool import -c cachefile手动导入缓存文件来使其工作,但是我仍然必须在重启之前运行zpool set cachefile = / etc / zfs / zpool.cache Pool稍后重启后导入它.
这就是systemctl状态zfs-import-cache的样子,

zfs-import-cache.service – 按缓存文件导入ZFS池
加载：已加载(/usr/lib/systemd/system/zfs-import-cache.service; static)
活动：不活动(死机)

cat / etc / sysconfig / zfs

我不确定这是否是一个已知问题,如果是,是否有任何解决方法？也许是一种在重启后保存我的数据集的简单方法,最好不需要缓存文件的开销.

解决方法 请确保启用了zfs服务(目标).这就是在启动/关闭时处理池导入/导出的原因.

zfs.target加载了活动的活动ZFS启动目标

你永远不应该为此而挣扎.如果有机会,请在zfs发行版上运行更新,因为我知道初创公司的服务在过去几个版本中有所改进：

[root@zfs2 ~]# rpm -qi zfsname        : zfsVersion     : 0.6.5.2Release     : 1.el7.centos
