Glusterfs （ls操作代码处理分析）
来源：互联网 发布：vb中chr(10)是什么意思 编辑：程序博客网 时间：2024/06/05 19:20
使用glusterfs3.3-release版本进行分析，ls命令执行后，抓取trace, 分析glusterfs的代码处理过程，用一台centos6.2虚拟机进行即可，创建卷及挂载过程步骤如下：
1. 官网下载release版本路径如下：http://www.gluster.org，下载后解压，然后我们先打入一个patch，使能glusterfs各个translator调用的trace，patch如下：
--- /root/stack.h 2013-06-13 00:57:40.244154611 -0700

从patch上可以看到，关键之处在STACK_WIND/UNWIND函数调用上加入trace信息，打入patch后，继续执行如下命令安装：
执行./autogen.sh && ./configure --enable-fusermount && make && make install
2. 启动glusterd
/etc/init.d/glusterd start
3.创建两个本地目录
mkdir /root/server-data1 /root/server-data2
4.创建客户端挂载的目录
mkdir /root/client-data
5.创建glusterfs卷(tcp+replictaion卷)
gluster volume create volume-rep replica 2 transport tcp localhost.localdomain:/root/server-data1 localhost.localdomain:/root/server-data2
6.启动卷
gluster volume start volume-rep
7.挂载卷（使用glusterfs-native 客户端协议）
mount -t glusterfs -o log-file=/var/log/gluster.log,log-level=TRACE localhost.localdomain:/volume-rep /root/client-data
[注意：log-level使用TRACE级别，或者默认方式，后面可以执行gluster volume set debug-gluster diagnostics.client-log-level TRACE 动态配置]
此后，我们所做的所有操作，都会记录在gluster.log文件中。
8.进入挂载目录/root/client-data中，执行touch test.txt文件，然后ls 执行后，我们可以打开gluster.log文件分析一下 ls命令在glusterfs文件系统协议中处理的全过程，日志及分析如下：
【注：】
通过下面的详细log分析，我们可以对应到代码函数进行细粒度分析，会发现虽然我们只建立了replication+tcp卷，实际内部默认配置了多个translator，总结如下，客户端translator的路径列举如下
fuse(client) -> io-stats(client)->md-cache(client)->quick-read(client)->io-cache(client)->defaults(client)->dht(client)->afr(client)->
rpc-clnt (client) .
P.S.： 后续我们再分析server端的处理路径
