最近由于在做一个实验需要搭建一套10G RAC环境，采用了 VMWARE 的方式，大家知道oracle rac是需要准备共享存储的，关于ocr和vote disk盘在节点1上进行分区后，然后进行绑定，执行 service rawdevices restart 可以看到绑定的设备。

[root@amto04 ~]# service rawdevices restartAssigning devices:            /dev/raw/raw1  -->   /dev/sdb1/dev/raw/raw1:  bound to major 8, minor 17           /dev/raw/raw2  -->   /dev/sdc1/dev/raw/raw2:  bound to major 8, minor 33           /dev/raw/raw3  -->   /dev/sdd1/dev/raw/raw3:  bound to major 8, minor 49           /dev/raw/raw4  -->   /dev/sde1/dev/raw/raw4:  bound to major 8, minor 65           /dev/raw/raw5  -->   /dev/sdf1/dev/raw/raw5:  bound to major 8, minor 81done

然后我在节点2，执行serivce rawdevices restart命令：

[root@amto05 ~]# service rawdevices restartAssigning devices:            /dev/raw/raw1  -->   /dev/sdb1/dev/raw/raw1:  bound to major 8, minor 17           /dev/raw/raw2  -->   /dev/sdc1Cannot locate block device '/dev/sdc1' (No such file or directory)           /dev/raw/raw3  -->   /dev/sdd1Cannot locate block device '/dev/sdd1' (No such file or directory)           /dev/raw/raw4  -->   /dev/sde1Cannot locate block device '/dev/sde1' (No such file or directory)           /dev/raw/raw5  -->   /dev/sdf1/dev/raw/raw5:  bound to major 8, minor 81done

sdc1,sdd1,sde1 三块盘绑定的有问题，通过fdisk是可以看得到的。

此时需要通过在节点2 执行 partprobe 命令即可。

[root@amto05 ~]# partprobe[root@amto05 ~]# service rawdevices restartAssigning devices:            /dev/raw/raw1  -->   /dev/sdb1/dev/raw/raw1:  bound to major 8, minor 17           /dev/raw/raw2  -->   /dev/sdc1/dev/raw/raw2:  bound to major 8, minor 33           /dev/raw/raw3  -->   /dev/sdd1/dev/raw/raw3:  bound to major 8, minor 49           /dev/raw/raw4  -->   /dev/sde1/dev/raw/raw4:  bound to major 8, minor 65           /dev/raw/raw5  -->   /dev/sdf1/dev/raw/raw5:  bound to major 8, minor 81done
