centos7中udev 裸设备绑定问题

今天做测试增加了十一块盘做测试，记录下关于裸设备绑定的权限不对的问题

1	/usr/lib/udev/rules.d/60-raw.rules 问题如下：

重启系统后发现有raw10 和raw11权限变成了root[root@rac1 ~]# ll /dev/raw total 0 crw-rw---- 1 grid asmadmin 162,  1 Dec 25 10:26 raw1 crw-rw---- 1 root disk     162, 10 Dec 25 10:26 raw10 crw-rw---- 1 root disk     162, 11 Dec 25 10:26 raw11 crw-rw---- 1 grid asmadmin 162,  2 Dec 25 10:26 raw2 crw-rw---- 1 grid asmadmin 162,  3 Dec 25 10:26 raw3 crw-rw---- 1 grid asmadmin 162,  4 Dec 25 10:26 raw4 crw-rw---- 1 grid asmadmin 162,  5 Dec 25 10:26 raw5 crw-rw---- 1 grid asmadmin 162,  6 Dec 25 10:26 raw6 crw-rw---- 1 grid asmadmin 162,  7 Dec 25 10:26 raw7 crw-rw---- 1 grid asmadmin 162,  8 Dec 25 10:26 raw8 crw-rw---- 1 grid asmadmin 162,  9 Dec 25 10:26 raw9 crw-rw---- 1 root disk     162,  0 Dec 25 10:26 rawctl [root@rac1 ~]# vi /usr/lib/udev/rules.d/60-raw.rules [root@rac1 ~]# 设备可以识别到 [root@rac1 ~]# raw -qa /dev/raw/raw1:  bound to major 8, minor 17 /dev/raw/raw2:  bound to major 8, minor 33 /dev/raw/raw3:  bound to major 8, minor 49 /dev/raw/raw4:  bound to major 8, minor 65 /dev/raw/raw5:  bound to major 8, minor 81 /dev/raw/raw6:  bound to major 8, minor 97 /dev/raw/raw7:  bound to major 8, minor 113 /dev/raw/raw8:  bound to major 8, minor 129 /dev/raw/raw9:  bound to major 8, minor 145 /dev/raw/raw10:  bound to major 8, minor 161 /dev/raw/raw11:  bound to major 8, minor 177查看配置文件如下 [root@rac1 ~]# cat  /usr/lib/udev/rules.d/60-raw.rules # # Enter raw device bindings here. # # An example would be: #   ACTION=="add", KERNEL=="sda", RUN+="/usr/bin/raw /dev/raw/raw1 %N" # to bind /dev/raw/raw1 to /dev/sda, or #   ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/usr/bin/raw /dev/raw/raw2 %M %m" # to bind /dev/raw/raw2 to the device with major 8, minor 1.

解决办法增加配置

将原来的配置

?

1 2	KERNEL=="raw[10]", MODE="0660", OWNER="grid", GROUP="asmadmin" KERNEL=="raw[11]", MODE="0660", OWNER="grid", GROUP="asmadmin"

　　多半是raw设备超过10十块之后不支持raw[10]写法，所以换位*匹配

?

1

修改如下

?

1	KERNEL=="raw*", MODE="0660", OWNER="grid", GROUP="asmadmin"

　　

 

重启后设备权限正常。
