我在Ubuntu 12.04机箱上运行官方glusterFS 3.5软件包,它充当客户机和服务器,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) [2014-06-17 08:20:52.998985] I [socket.c:3561:socket_init] 0-glusterfs: SSL support is NOT enabled [2014-06-17 08:20:52.999048] I [socket.c:3576:socket_init] 0-glusterfs: using system polling thread [2014-06-17 08:20:53.000373] E [socket.c:2161:socket_connect_finish] 0-glusterfs: connection to 127.0.0.1:24007 Failed (Connection refused) [2014-06-17 08:20:53.000427] E [glusterfsd-mgmt.c:1601:mgmt_rpc_notify] 0-glusterfsd-mgmt: Failed to connect with remote-host: 127.0.0.1 (No data available) [2014-06-17 08:20:53.000442] I [glusterfsd-mgmt.c:1607:mgmt_rpc_notify] 0-glusterfsd-mgmt: Exhausted all volfile servers [2014-06-17 08:20:53.013793] W [glusterfsd.c:1095:cleanup_and_exit] (-->/usr/lib/x86_64-linux-gnu/libgfrpc.so.0(rpc_transport_notify+0x27) [0x7f686e0160f7] (-->/usr/lib/x86_64-linux-gnu/libgfrpc.so.0(rpc_clnt_notify+0x1a4) [0x7f686e019cc4] (-->/usr/sbin/glusterfs(+0xcada) [0x7f686e6ddada]))) 0-: received signum (1),shutting down [2014-06-17 08:20:53.013830] I [fuse-bridge.c:5444:fini] 0-fuse: Unmounting '/var/www/shared/public/uploads'.
我的fstab包含：

我知道这曾经是Ulusntu的glusterFS 3.2中的一个错误,但我知道它已经在glusterFS 3.4的PPA包中解决了,如下所示：https://bugs.launchpad.net/ubuntu/+source/glusterfs/+bug/876648
我还记得这个在我用一些虚拟机运行的实验中工作(但是因为它只是工作,我看起来并不太深入).我看到gluster-client包提供了一个名为mounting-glusterfs.conf的upstart作业,它包含：
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运作.它似乎没有开箱即用.即使在网络启动后安装了glusterfs卷,它也会在glusterFS启动之前发生：
* Starting RPC portmapper replacement [ OK ] * Stopping rpcsec_gss daemon [ OK ] * Starting Start this job to wait until rpcbind is started or fails to s[ OK ] * Starting configure network device [ OK ] * Stopping Start this job to wait until rpcbind is started or fails to s[ OK ] * Starting Bridge socket events into upstart [ OK ] * Starting NSM status monitor [ OK ] * Stopping cold plug devices [ OK ] * Stopping log initial device creation [ OK ] * Starting load fallback graphics devices [ OK ] * Starting configure network device security [ OK ] * Starting load fallback graphics devices [fail] * Starting configure virtual network devices [ OK ] * Starting Send an event to indicate plymouth is up [ OK ] * Stopping Send an event to indicate plymouth is up [ OK ] * Starting Mount network filesystems [ OK ] * Stopping configure virtual network devices [ OK ] * Stopping Mount network filesystems [ OK ] * Starting Mount network filesystems [ OK ] * Stopping Mount network filesystems [ OK ] * Starting configure network device [ OK ] * Starting set sysctls from /etc/sysctl.conf [ OK ] * Stopping set sysctls from /etc/sysctl.conf [ OK ] The disk drive for /var/www/shared/public/uploads is not ready yet or not present.

有什么想法正在发生和/或如何修复它？
作为一个我不太兴奋的替代方案,我试着安装这些卷的新手工作.我将noauto添加到我的fstab glusterfs条目中,这样它们就不会自动挂载到引导项并创建一个包含这些内容的upstart作业：
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,未安装卷. /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 cotains：

其中我认为这是重要的一句话：
[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.
如果我手动运行服务mount_public_uploads start,它就可以正常运行.也许是在glusterfs准备好之前试图安装？
这似乎是一个已知的问题,根据
README.Ubuntu应该在Ubuntu 14.04中修复.
早期Ubuntu版本的可能解决方法可能是在glusterFS服务器启动后使用自定义upstart作业推迟卷装入.
