Pab*_*blo 8 ubuntu glusterfs ubuntu-12.04
我在同时充当客户端和服务器的 Ubuntu 12.04 机器上运行官方 GlusterFS 3.5 软件包，除了在启动时安装 GlusterFS 卷外，一切似乎都运行良好。这是我在日志文件中看到的：
[2014-06-17 08:20:52.969258] I [glusterfsd.c:1959:main] 0-/usr/sbin/glusterfs: Started running /usr/sbin/glusterfs version 3.5.0 (/usr/sbin/glusterfs --volfile-server=127.0.0.1 --volfile-id=/public_uploads /var/www/shared/public/uploads)

127.0.0.1:/private_uploads /var/www/shared/private/uploads glusterfs defaults,_netdev 0 0
我知道这曾经是 Ubuntu 的 GlusterFS 3.2 中的一个错误，但我知道它已在 GlusterFS 3.4 的 PPA 包中解决，如下所示：https : //bugs.launchpad.net/ubuntu/+source/glusterfs/+bug /876648
我还记得这在我用一些虚拟机运行的实验中工作（但由于它只是工作，我没有深入研究它）。我看到 gluster-client 软件包提供了一个名为 mount-glusterfs.conf 的新贵工作，其中包含：
author "Louis Zuckerman <me@louiszuckerman.com>"
description "Block the mounting event for glusterfs filesystems until the network interfaces are running"
instance $MOUNTPOINT
start on mounting TYPE=glusterfs
task
exec start wait-for-state WAIT_FOR=static-network-up WAITER=mounting-glusterfs-$MOUNTPOINT
但我不太确定它应该如何工作。它似乎不是开箱即用的。即使 glusterfs 卷的安装发生在网络启动之后，它也会发生在 GlusterFS 启动之前：

任何想法发生了什么和/或如何解决它？
作为一个我不太兴奋的替代方案，我尝试让一个新贵的工作来安装这些卷。我将 noauto 添加到我的 fstab glusterfs 条目中，以便它们不会自动安装在引导项中，并使用以下内容创建了一个新贵的工作：
description "Mount public uploads"
start on started glusterfs-server
exec mount /var/www/shared/public/uploads
当我重新启动服务器时，卷没有安装。/var/log/upstart/mount_public_uploads.log 包含：
Mount failed. Please check the log file for more details.
和 /var/log/glusterf/var-www-shared-public-uploads.log 包含：

其中我认为这是重要的一行：
[2014-06-19 15:01:50.619723] E [client-handshake.c:1742:client_query_portmap_cbk] 0-public_uploads-client-0: failed to get the port number for remote subvolume. Please run 'gluster volume status' on server to see if brick process is running.
如果我手动运行 service mount_public_uploads start，它安装得很好。也许它试图在 glusterfs 准备好之前安装？
根据README.Ubuntu ，这似乎是一个已知问题应该在 Ubuntu 14.04 中修复。
对于早期 Ubuntu 版本，一个可能的解决方法是在 GlusterFS 服务器启动后使用自定义 upstart 作业推迟卷安装。
