GlusterFS源码解析—— GlusterFS 命令行常见错误
原文地址：http://write.blog.csdn.net/postedit/25927643
问题1
[root@localhost ~]# gluster peer status
Connection failed. Please check if gluster daemon is operational.
原因：未开启glusterd服务
解决方法：开启glusterd服务
/etc/init.d/glusterd start
问题2
[root@localhost ~]# gluster peer probe 192.168.230.130
peer probe: failed: Probe returned with unknown errno 107
原因：日志中打印[2014-05-15 15:55:25.929461] I [glusterd-handler.c:2836:glusterd_probe_begin] 0-glusterd:Unable to find peerinfo for host: 192.168.230.130 (24007)
防火墙没开启24007端口
解决方法：开启24007端口或者关掉防火墙
/sbin/iptables -I INPUT -p tcp --dport 24007 -j ACCEPT # 开启24007端口
/etc/init.d/iptables stop # 关掉防火墙
注：
也可以使用主机名来代替IP，修改/etc/hosts文件实现
gluster peer probe server-130
问题3
volume create volume1 192.168.230.135:/tmp/brick1
volume create: volume2: failed
不能只使用一个server上的brick创建volume，需要至少两个brick，或者在client主机(这里为192.168.230.134)上使用一个brick创建volume。
gluster> volume create volume1 192.168.230.134:/tmp/brick1 force volume create: volume1: success: please start the volume to access data gluster> volume info Volume Name: volume1 Type: Distribute Volume ID: b01a2c29-09a6-41fd-a94e-ea834173a6a3 Status: Created Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: 192.168.230.134:/tmp/brick1 gluster> gluster> volume create volume2 192.168.230.134:/tmp/brick2 192.168.230.135:/tmp/brick2 force volume create: volume2: success: please start the volume to access data gluster> volume info Volume Name: volume1 Type: Distribute Volume ID: b01a2c29-09a6-41fd-a94e-ea834173a6a3 Status: Created Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: 192.168.230.134:/tmp/brick1 Volume Name: volume2 Type: Distribute Volume ID: 4af2e260-70ce-49f5-9663-9c831c5cf831 Status: Created Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: 192.168.230.134:/tmp/brick2 Brick2: 192.168.230.135:/tmp/brick2
问题4
创建一个volume后删除，再使用同名的brick创建volume失败。
gluster> volume create test 192.168.230.134:/tmp/brick1 force volume create: test: success: please start the volume to access data gluster> volume info Volume Name: test Type: Distribute Volume ID: c29f75d2-c9f5-4d6f-90c5-c562139ab9cd Status: Created Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: 192.168.230.134:/tmp/brick1 gluster> volume delete test force Usage: volume delete <VOLNAME> gluster> volume delete test Deleting volume will erase all information about the volume. Do you want to continue? (y/n) y volume delete: test: success gluster> volume create test 192.168.230.134:/tmp/brick1 force <span style="color:#FF0000;">volume create: test: failed: /tmp/brick1 or a prefix of it is already part of a volume</span>
因为volume delete时并未删掉create时创建的目录，需要手动删除后再使用。
