我有两台机器，profitmargin 和 revisionist，我在 profitsmargin 中创建了一个卷：
root@profitmargin:~# gluster volume info
Volume Name: uploads
Type: Distribute
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: profitmargin:/var/lib/gluster/brick01
在修订版中，我将这一行添加到 fstab 中，以便在启动时挂载它：
profitmargin:/uploads /mnt/uploads glusterfs defaults,_netdev 0 0
但当计算机启动时它并没有被安装：
root@revisionist:~# mount
/dev/mapper/revisionist-root on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
/dev/sda1 on /boot type ext2 (rw)
在日志文件中我发现了这一点：
root@revisionist:~# cat /var/log/glusterfs/mnt-uploads.log

如果我稍后尝试安装它，它就可以工作：
root@revisionist:~# mount -a
root@revisionist:~# mount

我正在运行 Ubuntu 12.04，并且我知道与 init 脚本相关的错误，但我正在运行 GlusterFS 版本 3.2.5-1ubuntu1，该版本已修复。我还知道一些 IPv6，因此我确保 IPv4 和 IPv6 都可以正常工作：
root@revisionist:~# ping profitmargin

还有其他想法可能导致此问题的原因和/或如何解决它吗？
答案1
我不是专家，但似乎与计算机 revisionlist 未通过 DNS 解析 profitsmargin 的 ip 地址有关。也许 mount 命令是在网络服务之前执行的，这就是 revisionlist 无法找到 profitsmargin 的原因。启动网络服务后，它能够找到该计算机。您应该尝试找到一种方法来挂载 GlusterFS 以等待网络服务上线。
答案2
就我而言，问题在于我在编译 glusterfs 时启用了 --with-ipv6-default。删除此选项后，主机名解析和显式 ipv4 地址又可以使用了。
在你的情况下，日志表明类似的事情：
[2014-05-19 10:41:18.704144] E [common-utils.c:125:gf_resolve_ip6] 0-resolver: getaddrinfo failed (Name or service not known)
gf_resolve_ip6 表示 glusterfs 尝试将其解析为 ipv6 地址
