用VMware添加磁盘并分区挂载

马热添加磁盘下次给出：
这里已经添加好磁盘，开始分区格式化

[root@udbs01 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x139d6e7b.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won’t be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It’s strongly recommended to
switch off the mode (command ‘c’) and change display units to
sectors (command ‘u’).

p primary partition (1-4)

First cylinder (1-6527, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-6527, default 6527):

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.

然后挂载分区
#创建目录
mkdir /oracle12c

#手动挂载：
mount /dev/sdb1 /oracle12c

#自动挂载：修改/etc/fstab

root@udbs01 ~]# mkdir /oracle12c
[root@udbs01 ~]# mount /dev/sdb1 /oracle12c
[root@udbs01 ~]# vim /etc/fstab
