![无法在 glusterfs 客户端上挂载 gluster fs:传输端点未连接](https://linux22.com/image/730971/%E6%97%A0%E6%B3%95%E5%9C%A8%20glusterfs%20%E5%AE%A2%E6%88%B7%E7%AB%AF%E4%B8%8A%E6%8C%82%E8%BD%BD%20gluster%20fs%EF%BC%9A%E4%BC%A0%E8%BE%93%E7%AB%AF%E7%82%B9%E6%9C%AA%E8%BF%9E%E6%8E%A5.png)
更新:升级到最新版本 5.2,从而更新日志。但是,问题依然存在。更新 2:也将客户端更新到 5.2,问题依然存在。
我有一个包含 3 个节点的 gluster 集群设置。
- 服务器1,192.168.100.1
- 服务器2,192.168.100.2
- 服务器3,192.168.100.3
它们通过内部网络 192.160.100.0/24 连接。但是,我想从网络外部连接客户端使用公共 IP其中一台服务器无法正常工作:
sudo mount -t glusterfs x.x.x.x:/datavol /mnt/gluster/

我错过了什么?
答案1
我也有同样的问题。
你有没有看到?https://bugzilla.redhat.com/show_bug.cgi?id=1659824
在 GlusterFS 中使用“IP”似乎并不“好”,因为客户端依赖于来自服务器的卷信息中的远程主机地址。如果服务器无法到达足够的 Gluster 节点,则无法使用其他节点的卷信息。请参阅https://unix.stackexchange.com/questions/213705/glusterfs-how-to-failover-smartly-if-a-mounted-server-is-failed
因此,问题是,挂载点到达节点 1,读取卷信息(请参阅/var/log/glusterfs/<volume>.log
)。有关其他节点的信息在option remote-host
)。然后,客户端尝试通过私有 IP 连接到该节点 - 并且失败(就我而言)。我假设,您的公共客户端无法访问私有 IP - 这就是背后的问题Transport endpoint is not connected
。
解决方案 A - 在 Gluster 集群中使用主机名而不是 IP 是可行的,因为您可以在其中/etc/hosts
为所有服务器创建别名。但这意味着 - 必须重建 Gluster 以使用 DNS 名称(即 Gluster 节点内的 192-IP 和客户端上的公共 IP)。我没有尝试从基于 IP 的 Gluster 切换到基于 DNS 的 Gluster(尤其是在生产中?)。
RH bugzilla 中的解决方案 B 对我来说不太清楚。我不明白应该包含什么glusterfs -f$local-volfile $mountpoint
- 尤其是忽略的真正挂载点选项是什么remote-host
以及它们与 vol-file 的含义是什么。SE 上的第二篇帖子中有回复。我想,这就是答案,但我还没有测试过。
所以 - 我认为,这不是一个错误,而是一个文档空白。构建卷的信息(砖块主机名)在客户端内部用于连接到挂载点选项中指定的其他节点。
