Every man at forty, if is not a fool, you should know that to maintain the body.

人到四十，如果不是傻子，就该知道保养身体。

错误描述

该错误发生在Oracle 19c RAC，静默安装Grid集群件的时候。

具体报错如下所示：

[grid@node1 grid_home]$ u01/app/19/grid_home/gridSetup.sh -silent -ignorePrereqFailure -responseFile upload/oracle/oracle_19c_install_grid.rsp -applyRU upload/oracle/patch/34518661

解决方法

清理磁盘组：

[root@node1 ~]# ls -ltr dev/mapper/asm*
lrwxrwxrwx 1 root root 7 Sep  3 13:49 dev/mapper/asm_data01 -> ../dm-5
lrwxrwxrwx 1 root root 7 Sep  3 15:11 dev/mapper/asm_ocr02 -> ../dm-3
lrwxrwxrwx 1 root root 7 Sep  3 15:11 dev/mapper/asm_ocr03 -> ../dm-4
lrwxrwxrwx 1 root root 7 Sep  3 15:25 dev/mapper/asm_ocr01 -> ../dm-2
[root@node1 ~]# 
[root@node1 ~]# ls -ltr /dev | grep zero
crw-rw-rw-  1 root root       1,   5 Sep  3 13:49 zero
[root@node1 ~]# 
[root@node1 ~]# dd if=/dev/zero of=/dev/mapper/asm_ocr01 bs=1M count=1000
1000+0 records in
1000+0 records out

[root@node1 ~]# 
[root@node1 ~]# dd if=/dev/zero of=/dev/mapper/asm_ocr02 bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB) copied, 11.2964 s, 92.8 MB/s
[root@node1 ~]# 
[root@node1 ~]# dd if=/dev/zero of=/dev/mapper/asm_ocr03 bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB) copied, 11.9448 s, 87.8 MB/s
[root@node1 ~]#

然后，再次执行安装就没有上述问题了：

END
