ubuntu – GlusterFS无法在启动时挂载

前端之家收集整理的这篇文章主要介绍了ubuntu – GlusterFS无法在启动时挂载前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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:

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:

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:

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.
