fdisk -l如上，df -h如下

[root@s150730 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg-root 108G 1.1G 102G 2% /

这样看/dev/sdb是没绑定目录的，然后mount一下出问题了

[root@s150730 ~]# mount /dev/sdb /home
mount: /dev/sdb is write-protected, mounting read-only
mount: unknown filesystem type ‘(null)’

好像是因为这块盘被做过raid？没办法用，
求教大佬如何正确挂载……
安徽网友:
为毛代码贴到loc上来会被翻译！

ps：哦，乌龙了，是我的浏览器插件……
