我使用 2 个服务器（ST0 和 ST1）和 1 个客户端 (STC) 运行 GlusterFS，卷名称是rep-volume。
我上网冲浪，阅读了所有解释如何解决安装问题的文章，但不幸的是没有什么可以帮助我。
我第一次使用以下命令时，它运行良好并且我具有写访问权限：
$ mount.glusterfs ST0:/rep-volume /mnt/replica/
但重启客户端后，我无法再次挂载它，结果如下：
$ mount.glusterfs ST0:/rep-volume /mnt/replica/
Mount failed. Please check the log file for more details.
日志文件如下所示：
$ cat /var/log/glusterfs/mnt-replica.log

如果有人能帮助我，我将非常感激。谢谢。
更新：
@FarazX 提供的答案确实很有帮助，解决了我的问题，但我仍然有兴趣找到为什么当我在客户端服务器上执行相同操作时这种情况起作用的原因（没有成功）？我在 bugzilla.redhat.com 上读了很多东西，但原因对我来说仍然有点模糊。
答案1
我遇到了同样的问题，但我尝试将客户端安装在同一台服务器上，并且效果很好。
在您的情况下，可以通过分别在 ST0 和 ST1 上运行以下命令来完成：
ST0: ~ root # mkdir /mnt/replica
ST0: ~ root # mount.glusterfs ST0:/rep-volume /mnt/replica/
ST0: ~ root # echo 'ST0:/rep-volume /mnt/replica glusterfs _netdev,fetch-attempts=10 0 0' >> /etc/fstab
&
ST1: ~ root # mkdir /mnt/replica
ST1: ~ root # mount.glusterfs ST1:/rep-volume /mnt/replica/
ST1: ~ root # echo 'ST1:/rep-volume /mnt/replica glusterfs _netdev,fetch-attempts=10 0 0' >> /etc/fstab
注意检查您的防火墙配置和规则。
我希望这可以解决您的问题。
