Debian添加raw裸设备

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
