linux下san存储多路径软件的配置

linux下，san存储多路径软件的配置

linux下，san存储多路径软件的配置

1、使用 ntsysv 命令 将mulitipath服务开启

[*] multipathd

2、启动该服务

[root@mail init.d]# service multipathd start Starting multipathd daemon:

3、修改配置文件/etc/multipath.conf

vi /etc/multipath.conf

# This is a basic configuration file with some examples, for device mapper # multipath.

# For a complete list of the default configuration values, see

# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.defaults # For a list of configuration options with descriptions, see

# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.annotated

# Blacklist all devices by default. Remove this to enable multipathing # on the default devices. blacklist {

[color=Red]# devnode \}

## By default, devices with vendor = \## blacklisted. To enable mulitpathing on these devies, uncomment the ## following lines. #blacklist_exceptions {

4、使用 multipath -F 删除现有路径

5、multipath -v2 格式化路径

6、使用 multipath -ll 查看多路径

[root@mail /]# multipath -ll

mpath0 (3600508b40006ea6e0001a000002a0000) dm-2 HP,HSV210 [size=500G][features=1 queue_if_no_path][hwhandler=0] \\_ round-robin 0 [prio=100][active] \\_ 0:0:2:1 sdc 8:32 [active][ready] \\_ 0:0:3:1 sdd 8:48 [active][ready] \\_ round-robin 0 [prio=20][enabled] \\_ 0:0:0:1 sda 8:0 [active][ready] \\_ 0:0:1:1 sdb 8:16 [active][ready]

7、使用fdisk -l 查看多路径的情况

[root@mail /]# fdisk -l

Disk /dev/dm-2 doesn't contain a valid partition table

8、格式化

mkfs -t extx /dev/dm-2

9、挂载即可使用

#fdisk /dev/sdc #m #n #p #l #w #fdisk -l

#mkfs -t ext3 /dev/sdc1 5.配置自动挂载 #mkdir /test

#tune2fs -l /dev/sdc1 |grep uuid
