我们的FreeNAS服务器日志不断充实

我们可以做什么？
已经填满了/var/log这样/ var就是“109％”！ 我可以以某种方式停止日志logging吗？
目前我们正在更换其中一个RAIDZ的坏驱动器。

看起来发生了什么事情是，坏的驱动器不仅是RAIDZ的一部分，而且还拥有一个交换分区，它不仅是活动的，而且还有一些交换分区。
FreeNAS默认创build交换分区时添加驱动器，实际上可能是一个可靠性问题，如果你真的结束了交换数据，因为交换没有冗余。 参见https://bugs.freenas.org/issues/208了解一些这方面的讨论。
在我看来，您可能希望在此之后重新启动以恢复到已知的良好状态，因为不清楚丢失的换出页面所保存的数据。
