mount: you must specify the filesystem type

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

 

1 2	# mount /dev/vdb /home mount: you must specify the filesystem type

先执行：mkfs.ext3 /dev/vdb

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Use tune2fs -c or -i to override.

再mount 即可：

1	#mount -t ext3 /dev/vdb /home

[root@iZ2834y8cmdZ ~]# mount /dev/vdb1 /d02
