/dev/sdb1 已经挂载或 /mnt/mountpoint3 忙解决办法

在挂载硬盘分区的时候，会出现mount: /dev/sdd1 already mounted or /data3 busy或者是在执行格式化分区的时候也会出现

/dev/hdb1 is apparently in use by the system; will not make a filesystem here!

解决方法：
[root@localhost ~]# dmsetup status

ResultFromHadoop-ResultFromHadoop: 0 3907026944 linear
ResultFromHadoop-ResultFromHadoop: 3907026944 3907026944 linear
ResultFromHadoop-ResultFromHadoop: 7814053888 3907026944 linear

[root@localhost ~]# dmsetup remove_all

[root@localhost ~]# dmsetup status

No devices found

再次执行mount /dev/sdd1 /data3就可以进行挂载了
