linux mount报错：you must specify the filesystem type的解决方法

最近工作中遇到一个问题，在linux mount /dev/vdb 到 /home 分区时报错：

# mount /dev/vdb /home
mount: you must specify the filesystem type

先执行：mkfs.ext3 /dev/vdb

# mkfs.ext3 /dev/vdb
mke2fs 1.41.12 (17-may-2010)
filesystem label=
os type: linux
block size=4096 (log=2)
fragment size=4096 (log=2)
stride=0 blocks, stripe width=0 blocks
32768000 inodes, 131072000 blocks
6553600 blocks (5.00%) reserved for the super user
first data block=0
maximum filesystem blocks=4294967296
4000 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
superblock backups stored on blocks: 
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 
4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 
102400000

writing inode tables: done 
creating journal (32768 blocks): done
writing superblocks and filesystem accounting information: done

this filesystem will be automatically checked every 25 mounts or
180 days, whichever comes first. use tune2fs -c or -i to override.

再mount 即可：

#mount -t ext3 /dev/vdb /home
