一.检查系统是否已经启用了raw模块
root@frog:~# lsmod|grep raw
如果系统没有启用raw模块!
二. 设置系统自动启用raw
root@frog:~# echo raw >> /etc/modules root@frog:~# cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. # Parameters can be specified after the module name. loop raw
三. reboot重启系统, 再次检查是是否已经启用raw模块
root@frog:~# lsmod|grep raw raw 12498 0
四."基于卷组(VG)创建逻辑卷(LV)"
root@frog:~# lvcreate -n stores_demo01 -L 2G frog
五. .将原始设备映射到新建的逻辑卷(分区)
root@frog:~# raw /dev/raw/raw1 /dev/frog/stores_demo01 /dev/raw/raw1: bound to major 254, minor 6
再检查一下:
root@frog:~# raw -qa /dev/raw/raw1: bound to major 254, minor 6
