linux挂载raw设备,linux创建raw设备

总结一下，看了一下他们的blog，几乎没有谁详细的总结raw的创建。

其实raw设备创建要分多路径链路创建和普通创建。

---情况二 (不是多路径)

[root@DP1 ~]# more /etc/sysconfig/rawdevices

# raw device bindings

# format:

# example: /dev/raw/raw1 /dev/sda1

# /dev/raw/raw2 8 5

#crs

/dev/raw/raw1 /dev/sdb1

#data

/dev/raw/raw2 /dev/sdb2

/dev/raw/raw3 /dev/sdd

/dev/raw/raw4 /dev/sdh

/dev/raw/raw5 /dev/sdj

[root@DP1 ~]#

设置权限

vi /etc/rc.local

[oracle@DP2 dbs]$ more /etc/rc.local

#!/bin/sh

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

chown grid:oinstall /dev/raw/raw1

chown grid:oinstall /dev/raw/raw2

chown grid:oinstall /dev/raw/raw3

chown grid:oinstall /dev/raw/raw4

chmod 660 /dev/raw/raw1

chmod 660 /dev/raw/raw2

chmod 660 /dev/raw/raw3

chmod 660 /dev/raw/raw4

touch /var/lock/subsys/local

删除裸设备

raw /dev/raw/raw1 0 0

使裸设备重启

/etc/init.d/rawdevices restart

--查看裸设备

[root@DP2 product]# raw -qa

/dev/raw/raw1: bound to major 8, minor 16

/dev/raw/raw2: bound to major 8, minor 48

/dev/raw/raw3: bound to major 8, minor 112

/dev/raw/raw4: bound to major 8, minor 144

[root@DP2 product]#

另一种配置方式, 通用于linux5.x 和linux6.x

vi /etc/udev/rules.d/60-raw.rules

# Enter raw device bindings here.

# An example would be:

# ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"

# to bind /dev/raw/raw1 to /dev/sda, or -- 注意这里有个OR

# ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"

# to bind /dev/raw/raw2 to the device with major 8, minor 1.

比如：

fdisk -l

Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes

255 heads, 63 sectors/track, 243201 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes

255 heads, 63 sectors/track, 243201 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

[root@SE ~]# more /etc/udev/rules.d/60-raw.rules

# Enter raw device bindings here.

# An example would be:

# ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="raw[1-2]", OWNER="grid", GROUP="oinstall", MODE="660"

[root@SE ~]# start_udev
