我之前已在 LAN 上的两个节点（IP 分别为(hostname ) 和(hostname )）上设置了几个 GlusterFS 卷（称为cyclorana0和）。命令等均成功执行，两个节点可以正确看到彼此和卷。这两个节点运行的是 Armbian Linux 4.14.144-odroidxu4，版本为 3.13.2-1ubuntu1。cyclorana110.0.2.4alboguttata10.0.2.5verrucosaprobeglusterfs-server
我还设置了一个 RHEL 客户端（glusterfs软件包版本为 3.12.2）来通过 挂载卷/etc/fstab，并且它已经运行了几个月，甚至在多次重启之后也是如此。以下是内容：
10.0.2.5:/cyclorana0 /home/[username]/cyclorana0 glusterfs defaults,_netdev 0 0
10.0.2.5:/cyclorana1 /home/[username]/cyclorana1 glusterfs defaults,_netdev 0 0
但是，昨天重启 RHEL 客户端后，挂载失败。我尝试手动运行后mount -a，只得到以下信息：
Mount failed. Please check the log file for more details.
Mount failed. Please check the log file for more details.
我能想到的唯一日志是 中的日志/var/log/glusterfs/，而且我确实找到了与我的尝试相对应的日志文件。两个卷的输出相同，因此这里是其中一个示例：

我几乎看不懂这些日志，但据我所知，我的 RHEL 客户端可以“看到”该卷，但不知何故无法挂载它。日志中的主要问题行似乎是（如果我错了请告诉我）：
[2019-09-21 02:21:59.883477] E [MSGID: 101075] [common-utils.c:482:gf_resolve_ip6] 0-resolver: getaddrinfo failed (family:2) (Name or service not known)

我对这个错误感到困惑DNS resolution，因为我直接通过它的 LAN IP 进行连接，并且 RHEL 客户端也在同一个 LAN 上。
我还尝试从同一 LAN 上的单独 Manjaro Linux 客户端进行安装，但产生了相同的错误消息。
我该如何排除故障并修复此问题以便可以安装这些卷？谢谢。
PS 这是安装时的日志成功的：
