今天自己的虛擬機磁盤用完成,於是想加一磁盤,當掛載時發現報錯you must specify the filesystem type。(注:我的系統環境是lcentos6.3裝在virtualbox的虛擬機)。
原來是因為該磁盤沒有格式分區導致的於是有了以下操作:
1)先查看一下當前的系統情況,新加的盤是sdb
-
[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 disk
2)嘗試掛載,報錯
-
[root@test ~]# mount /dev/sdb /disk
-
mount: you must specify the filesystem type
3)格式化該磁盤
-
[root@test ~]# mkfs.ext3 /dev/sdb
-
mke2fs 1.41.12 (17-May-2010)
-
/dev/sdb is entire device, not just one partition!
-
無論如何也要繼續? (y,n) y

4)掛載成功

-
[root@test disk]# ls
-

5)增加開機啟動
