Gluster只读文件系统

Question

我被这个问题困住了，我无法解决它。我们有一个网站，这样人们就可以在某个路径(比如临时目录)上传他们的视频，然后我们的管理员去把这些视频转移到服务器上的另一个位置，这个存储的后端突然出现了glusterfs，我不知道为什么和如何解决它，在我们管理员重新尝试移动这些文件之后，这个问题就会解决，而且我应该说，我是这家公司的一个新系统管理员，我对gluster并不熟悉。

这很可能是因为GlusterFS使用的底层块设备遇到了I/O错误，并且被重新安装为只读文件系统(以防止进一步的损坏)。我首先会去托管砖块的机器，并在那里做一个dmesg，看看内核是否报告了这样的错误。
