增加了一个/dev/sdb: 2147MB.....
创建挂载点:mkdir /mnt/sdb1
挂载sdb:mount /dev/sdb
/mnt/sdb1
查看是否挂载成功:df -h

最后出现了sdb,则挂载成功;
②自动挂载

注:第一列为设备号或该设备的卷标
第二列为挂载点
第三列为文件系统
第四列为文件系统参数
第五列为是否可以用demp命令备份。0:不备份,1:备份,2:备份,但比1重要性小。设置了该参数后,Linux中使用dump命令备份系统的时候就可以备份相应设置的挂载点了。
第六列为是否在系统启动的时候,用fsck检验分区。因为有些挂载点是不需要检验的,比如:虚拟内存swap、/proc等。0:不检验,1:要检验,2要检验,但比1晚检验,一般根目录设置为1,其他设置为2就可以了
reboot
