自动挂载裸设备及权限

原创 Linux操作系统 作者:mycisco 时间:2011-04-13 11:47:16 0 删除 编辑
自动挂载裸设备
方法一: OEL5
vi /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2
/dev/raw/raw3 /dev/sdb3
/etc/init.d/rawdevices status/restart/...


方法二: OEL5/redhat5下


vi /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw3 %N"


启动后权限
vi /etc/udev/rules.d/65-raw-permissions.rules
# Set permissions of raw bindings to Oracle Clusterware devices
KERNEL=="raw1", WNER="oracle", GROUP="oinstall", MODE="660"
KERNEL=="raw2", WNER="oracle", GROUP="oinstall", MODE="660"
KERNEL=="raw3", WNER="oracle", GROUP="oinstall", MODE="660"



资料:
Redhat 5 以上版本已经取消了对裸设备的支持,所以在安装 Oracle RAC 时所使用的的裸设备,需要通过 Udev 进行设置:

设置重新启动自动挂载裸设备
vi /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw3 %N"

注意确定raw命令在/bin目录下,有的linux是在/usr/bin目录下

vi /etc/udev/rules.d/65-raw-permissions.rules
# Set permissions of raw bindings to Oracle Clusterware devices
KERNEL=="raw1", WNER="root", GROUP="oinstall", MODE="660"
KERNEL=="raw2", WNER="oracle", GROUP="oinstall", MODE="660"
KERNEL=="raw3", WNER="oracle", GROUP="oinstall", MODE="660"

以上方法也适用其他使用udev挂载设备的linux版本.

具体请参考 Oracle 官方文档:

Note 465001.1
- Configuring raw devices (singlepath) for Oracle Clusterware10gRelease 2 (10.2.0) on RHEL5/ OEL5

Hi,

What kind of OS are you running ? Please upload the output of "uname -a".
If you are using EL5/RHEL5, that's right. You can't find the folder /etc/udev/permissions.d. Please follow the following steps:

1. Add udev permission rules to /etc/udev/rules.d/65-raw-permissions.rules file
2. Add the udev permission rules to the /etc/udev/rules.d/65-raw-permissions.rules file, for example:
# Set permissions of raw bindings to Oracle Clusterware devices
KERNEL=="raw1", WNER="root", GROUP="oinstall", MODE="640"
KERNEL=="raw2", WNER="oracle", GROUP="oinstall", MODE="640"
