基本上搭建glusterfs都是用了2个副本，用来保证数据冗余
建立新卷，/export/test-vol目录不用事先建立，会自动建立的：
1gluster volume create test-vol replica 2 transport tcp 172.16.8.5:/export/test-vol/ 172.16.8.6:/export/test-vol/
如上建立新卷后，test-vol的属主是root，如果我们想基于gfs之上做个虚拟的vsftpd，建设用户是virtual.virtual，500.500
设置卷uid/gid属性：
1gluster volume set test-vol storage.owner-uid 500
2gluster volume set test-vol storage.owner-gid 500
设置卷的quota空间配额：
1gluster volume quota test-vol enable
2gluster volume quota test-vol limit-usage / 10GB
3gluster volume quota test-vol limit-usage /path/in/volume 2G
4gluster volume set test-vol features.quota-timeout 30
5gluster volume quota test-vol list
6gluster volume quota test-vol list /path/in/volume
去掉quota限制：
1gluster volume quota test-vol remove /
2gluster volume quota test-Vol remove /path/in/volume
优化tcp参数：
1gluster volume set test-vol diagnostics.brick-log-level WARNING
2gluster volume set test-vol diagnostics.client-log-level WARNING
3gluster volume set test-vol nfs.enable-ino32 on
4gluster volume set test-vol nfs.addr-namelookup off
5gluster volume set test-vol nfs.disable on
6gluster volume set test-vol performance.cache-max-file-size 2MB
7gluster volume set test-vol performance.cache-refresh-timeout 4
8gluster volume set test-vol performance.cache-size 256MB
9gluster volume set test-vol performance.write-behind-window-size 4M
10gluster volume set test-vol performance.io-thread-count 32
设置卷访问权限
1gluster volume set test-vol auth.allow 192.168.2.*
2gluster volume set test-vol auth.reject 192.168.2.*
监控
1gluster volume profile zfws-vol start
2gluster volume profile zfws-vol info
