GlusterFS学习笔记(翻译by 张文超)(7)

Install the packages required only on CentOS:

$ sudo yum -y install python-webob1.0 python-paste-deploy1.5 python-sphinx10 redhat-rpm-config

6.1.4 Preparation steps for RHEL 6.x (only)

$ sudo yum -y install `[`http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm`](http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm)

$ sudo yum -y --enablerepo=rhel-6-server-optional-rpms install python-webob1.0 \\

6.2 Common Steps

6.2.1 step 1 below:

If you're on RHEL/CentOS 5.x and get a message about lvm2-devel not being available, it's ok. You can ignore it. :)

If you're on RHEL/CentOS 6.x and get any messages about python-eventlet, python-netifaces, python-sphinx and/or pyxattr not being available, it's ok. You can ignore them. :) Install the needed packages

$ sudo yum -y --disablerepo=rhs* --enablerepo=*optional-rpms install git autoconf \\ automake bison dos2unix flex fuse-devel glib2-devel libaio-devel \\

libattr-devel libibverbs-devel librdmacm-devel libtool libxml2-devel lvm2-devel make \\ openssl-devel pkgconfig pyliblzma python-devel python-eventlet python-netifaces \\ python-paste-deploy python-simplejson python-sphinx python-webob pyxattr readline-devel \\ rpm-build systemtap-sdt-devel tar libcmocka-devel Clone the GlusterFS git repository

$ git clone `[`git://git.gluster.org/glusterfs`](git://git.gluster.org/glusterfs) $ cd glusterfs

Choose which branch to compile

$ git branch -a | grep release remotes/origin/release-2.0

remotes/origin/release-3.0 remotes/origin/release-3.1 remotes/origin/release-3.2 remotes/origin/release-3.3 remotes/origin/release-3.4

remotes/origin/release-3.5

$ git checkout release-3.4 $ ./autogen.sh

$ ./configure --enable-fusermount $ make dist

$ cd extras/LinuxRPM $ make glusterrpms

That should complete with no errors, leaving you with a directory containing the RPMs. $ ls -l *rpm

第7章 Swift对象存储

原来称为gluster-swift或者UFO(Unified File and Object)现在已经废弃。称为SwiftOnFile。新旧版本区别如下：

Gluster-Swift 只支持一个 Swift 账户. 挂载层次结构:container/object Over-rides account server, container server and object server. We need to keep in sync with upstream Swift and often may need code changes or workarounds to support new Swift features Does not use DBs for accounts and container.A container listing involves a filesystem crawl.A HEAD on account/container gives inaccurate or stale results without FS crawl. SwiftOnFile 一个GlusterFS 卷或 XFS 分区可以有多个账户挂载层次结构: acc/container/object Implements only object-server. Very less need to catch-up to Swift as new features at proxy,container and account level would very likely be compatible with SwiftOnFile as it's just a storage policy. Uses Swift's DBs to store account and container information. An account or container listing does not involve FS crawl. Accurate info on HEAD to account/container – ability to support account quotas. GET on a container and account only lists objects GET on a container and account lists actual files in filesystem. PUT over Swift. Files created over filesystem interface do not appear in container and object listings. Standalone deployment required and does not integrate with existing Swift cluster. Integrates with any existing Swift deployment as a Storage Policy.
