When the Linux virtual machine mounts the hard disk, you are prompted to specify how to solve it?

The disk space in the Linux virtual machine is not enough. When you mount a hard disk, an error message appears, that is, you must specify the filesystem type. What does this mean? Friends who don't understand may wish to come along with Xiaobian to understand the solution.

phrase in English means must specify a system partition. (Note: My system environment is lcentos6.3 virtual machine installed in virtualbox)

It turns out that the disk has no format partition, so the following operation:

1, first view In the current system situation, the newly added disk is 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, try to mount, report error

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

mount: you must specify the filesystem type

3. Format the disk

[root@test ~]# mkfs.ext3 /dev/sdb

mke2fs 1.41.12 (17-May-2010)

/dev/sdb is entire device, not ju St one partition!
