redhat 5.4 下 Oracle RAC 报 raw 设备大小 错误

在Redhat 5.4 上安装oracle 10g的RAC。 在安装Clusterware 的时候,出现错误:

        

   

  redhat 5.4 下 Oracle RAC 报 raw 设备大小 错误_第1张图片

        Raw 设备的大小肯定是没有问题,因为我分配的raw 是200M一个,但是它只识别了16M。  配置文件就那么几步,看了几遍都没有发现问题。 google 百度也没有什么有价值的信息。

 

磁盘分区大小:

[root@rac1 raw]# fdisk -l

Disk /dev/sdb: 419 MB, 419430400 bytes

64 heads, 32 sectors/track, 400 cylinders

Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sdb2             200         400      205824   83  Linux

裸设备信息:

[root@rac1 raw]# ls -lrt /dev/raw/raw*

crw-rw---- 1 oracle oinstall 162, 3 Sep  8 05:14 /dev/raw/raw3

crw-rw---- 1 oracle oinstall 162, 2 Sep  8 05:14 /dev/raw/raw2

crw-rw---- 1 oracle oinstall 162, 5 Sep  8 05:14 /dev/raw/raw5

crw-rw---- 1 oracle oinstall 162, 4 Sep  8 05:14 /dev/raw/raw4

crw-rw---- 1 oracle oinstall 162, 1 Sep  8 05:14 /dev/raw/raw1

 

 

报这种错,肯定出在raw的配置上,后来在看 /etc/udev/rules.d/60-raw.rules 配置的时候发现和 提示中的有点出入,尝试的修改了一下成如下格式:

 

[root@rac2 /]# 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"

# to bind /dev/raw/raw1 to /dev/sda, 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.

 

ACTION=="add", KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdb2",RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw3 %N"

ACTION=="add", KERNEL=="sdc2",RUN+="/bin/raw /dev/raw/raw4 %N"

ACTION=="add", KERNEL=="sdc3",RUN+="/bin/raw /dev/raw/raw5 %N"

ACTION=="add", KERNEL=="raw[1-5]", OWNER="oracle", GROUP="oinstall", MODE="660"

 

再次尝试安装clusterware,居然没有报错了,悲壮啊。

 

在这贴一下原来的信息(这种配置是错误的):

 

ACTION=="add", KERNEL=="/dev/sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="/dev/sdb2",RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="/dev/sdc1",RUN+="/bin/raw /dev/raw/raw3 %N"

ACTION=="add", KERNEL=="/dev/sdc2",RUN+="/bin/raw /dev/raw/raw4 %N"

ACTION=="add", KERNEL=="/dev/sdc3",RUN+="/bin/raw /dev/raw/raw5 %N"

ACTION=="add", KERNEL=="raw[1-5]", OWNER="oracle", GROUP="oinstall", MODE="660"

 

这两段的不同在于KERNEL 参数上,之前我写成/dev/sdb1 这种格式,这种会报开始时的错误,正确的写法是直接写sdb1就可以了。 这个东西搞了半天的时间,太杯具了。 不过问题解决了,也吸取教训了。
