Debian添加raw裸设备

Posted 2020-07-21 薛定谔

一.检查系统是否已经启用了raw模块

[email protected]:~# lsmod|grep raw

如果系统没有启用raw模块!

 

二. 设置系统自动启用raw

[email protected]:~# echo raw >> /etc/modules 
[email protected]:~# 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

[email protected]:~# lsmod|grep raw
raw                    12498  0

 

四."基于卷组(VG)创建逻辑卷(LV)"

[email protected]:~# lvcreate -n stores_demo01 -L 2G frog

五. .将原始设备映射到新建的逻辑卷(分区)

[email protected]:~# raw /dev/raw/raw1 /dev/frog/stores_demo01 
/dev/raw/raw1:  bound to major 254, minor 6

  再检查一下:

[email protected]:~# raw -qa
/dev/raw/raw1:  bound to major 254, minor 6
