RHEL 6.9 udev 将lv绑定raw devices

2018年05月03日  | 移动技术网科技  | 我要评论

环境

RHEL6|RHEL7，LVM2，RAW device

用途

使用LVM的lv逻辑卷绑定裸设备

1. 编辑 /etc/udev/rules.d/60-raw.rules 添加如下：

ACTION!="add|change", GOTO="raw_end"
# Create raw character device mapping:
ENV{DM_VG_NAME}=="vgoradata", ENV{DM_LV_NAME}=="lv_5G_1", RUN+="/bin/raw /dev/raw/raw1 %N"
ENV{DM_VG_NAME}=="vgoradata", ENV{DM_LV_NAME}=="lv_5G_2", RUN+="/bin/raw /dev/raw/raw2 %N"
ENV{DM_VG_NAME}=="vgoradata", ENV{DM_LV_NAME}=="lv_5G_3", RUN+="/bin/raw /dev/raw/raw3 %N"
# To set permissions:
KERNEL=="raw*", OWNER:="grid", GROUP:="asmadmin", MODE:="0660" LABEL="raw_end

2.使规则生效

udevadm control --reload-rules
udevadm trigger --type=devices --action=change

3.查看结果

# raw -qa
/dev/raw/raw1:  bound to major 253, minor 0
/dev/raw/raw2:  bound to major 253, minor 1
/dev/raw/raw3:  bound to major 253, minor 2
# lvs -o +lv_kernel_major,lv_kernel_minor
   LV      VG        Attr       LSize Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert KMaj KMin
   lv_5G_1 vgoradata -wi-a----- 2.00g                                                      253    0
   lv_5G_2 vgoradata -wi-a----- 2.00g                                                      253    1
   lv_5G_3 vgoradata -wi-a----- 2.00g                                                      253    2
