linux中掛載硬盤報錯(you must specify the filesystem type)

今天本身的虛擬機磁盤用完成,因而想加一磁盤,當掛載時發現報錯you must specify the filesystem type。(注:個人系統環境是lcentos6.3裝在virtualbox的虛擬機)node

  原來是由於該磁盤沒有格式分區致使的因而有了如下操做:centos

  1)先查看一下當前的系統狀況,新加的盤是sdbide

 代碼以下  

[root@test ~]# lsblk
NAME                        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sr0                          11:0    1  1024M  0 rom 
sda                           8:0    0     8G  0 disk
├─sda1                        8:1    0   500M  0 part /boot
└─sda2                        8:2    0   7.5G  0 part
  ├─VolGroup-lv_root (dm-0) 253:0    0   6.6G  0 lvm  /
  └─VolGroup-lv_swap (dm-1) 253:1    0   992M  0 lvm  [SWAP]
sdb                           8:16   0     8G  0 diskspa

  2)嘗試掛載,報錯操作系統

 代碼以下  
[root@test ~]# mount /dev/sdb /disk

  mount: you must specify the filesystem typeorm

  3)格式化該磁盤ip

 代碼以下  
[root@test ~]# mkfs.ext3 /dev/sdb
mke2fs 1.41.12 (17-May-2010)
/dev/sdb is entire device, not just one partition!
不管如何也要繼續? (y,n) y

[root@test ~]#

  4)掛載成功ci

 代碼以下  


[root@test ~]# cd /disk/
[root@test disk]# ls
lost+found虛擬機

  5)增長開機啓動it
