fdisk /dev/vdb

[root@min-hadoop-rm ~]# fdisk /dev/vdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x9a8822d2.
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').

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

   Command (m for help):

   Command action
   e   extended
   p   primary partition (1-4)

   p 입력

   Partition number (1-4): 1

First cylinder (1-208050, default 1):

filesystem 생성

mkfs.ext4 /dev/vdb1

마운트

mkdir /data1
mount /dev/vdb1 /data1

영구 마운트 ( 영구는 없다. )

UUID 확인
