Linux下配置多路径软件（openfiler模拟共享盘）

1.安装rpmdevice-mapper-1.02.79-8.el6.x86_64.rpmdevice-mapper-event-1.02.79-8.el6.x86_64.rpmdevice-mapper-multipath-0.4.9-72.el6.x86_64.rpmrpm -ivh device-mapper-multipath-libs-0.4.9-72.el6.x86_64.rpm rpm -ivh device-mapper-1.02.79-8.el6.x86_64.rpmrpm -ivh device-mapper-event-1.02.79-8.el6.x86_64.rpm rpm -ivh device-mapper-multipath-libs-0.4.9-72.el6.x86_64.rpmrpm -ivh device-mapper-multipath-0.4.9-72.el6.x86_64.rpm2.设置开机启动，并检查安装包是否正常[root@lmsin ~]# chkconfig multipathd on[root@lmsin ~]# service multipathd startStarting multipathd daemon:                                [  OK  ][root@lmsin ~]# lsmod | grep dm_multipathdm_multipath           17724  0dm_mod                 84209  18 dm_multipath,dm_mirror,dm_log3.配置multipath使其正常工作，编辑/etc/multipath.conf,开放如下内容：[root@lmsin ~]# find / -name multipath.conf/usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf[root@lmsin ~]# cp /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf /etc/vi /etc/multipath.confdefaults {        user_friendly_names yes}blacklist {        devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st|sda)[0-9]*"        devnode "^hd[a-z]"}4.完成之后执行如下命令发现多路径multipath -v2  [root@lmrac2 Packages]#  modprobe dm-multipath[root@lmrac2 Packages]#  multipath -F[root@lmrac2 Packages]# multipath dm-multipath[root@lmrac2 Packages]# multipath dm-round-robin[root@lmrac2 Packages]#  service multipathd restartokStopping multipathd daemon: [  OK  ]Starting multipathd daemon: [  OK  ][root@lmrac2 Packages]# multipath -v2[root@lmrac2 Packages]# multipath -ll[root@lmrac1 ~]# ll /dev/mapper/*crw-rw---- 1 root root 10, 58 Sep 19 12:14 /dev/mapper/controllrwxrwxrwx 1 root root      7 Sep 19 12:14 /dev/mapper/mpatha -> ../dm-3lrwxrwxrwx 1 root root      7 Sep 19 12:14 /dev/mapper/mpathb -> ../dm-2lrwxrwxrwx 1 root root      7 Sep 19 12:14 /dev/mapper/mpathc -> ../dm-5lrwxrwxrwx 1 root root      7 Sep 19 12:14 /dev/mapper/mpathd -> ../dm-4lrwxrwxrwx 1 root root      7 Sep 19 12:14 /dev/mapper/mpathe -> ../dm-6
