Format hard drive error prompts a large pile of English

The error is as follows:

[root@hpf-linux~]# mke2fs-t ext3-b 2048-m 3/DEV/SDB5

MKE2FS 1.41.12 (17-may-2010)

/DEV/SDB5 is apparently in with the system; Would not make a file system here!

Hint/DEV/SDB5 is being used. /DEV/SDB5 is being DM management, so we create the file system prompts the error, we manually removed, you can create a normal file system, the operation is as follows:

[root@hpf-linux~]# cat/proc/partitions
