在Linux服务器（虚拟机）上使用fdisk添加分区、格式化分区后，遇到了Linux Error: 22: Invalid argument错误，操作步骤如下所示

Disk /dev/sdd doesn‘t contain a valid partition table[root@oracle-server ~]# fdisk /dev/sdd
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won‘t be recoverable.
The number of cylinders for this disk is set to 10443.There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

处理完成后，登录ORACLE数据库出现错误，检查告警日志，发现如下错误信息：
检查/var/log/messages ，没有发现什么错误信息
网上搜索到一篇资料(请见参考资料) 介绍了使用fdisk出现Linux Error: 22: Invalid argument的原因.
Run "kpartx -a" after FDISK is completed to add all partition mappings on the newly-created multipath device
当时没有使用这个命令去操作，因为不敢确认这个命令能否解决问题，于是重启Server来解决问题。下次遇到这种情况也可以使用kpartx命令试试。
kpartx -a /dev/sdd1
