错误如下:
[root@hpf-linux~]# mke2fs -t ext3 -b 2048 -m 3 /dev/sdb5
mke2fs 1.41.12 (17-May-2010)
/dev/sdb5 is apparently in use by the system; will not make a 文件系统 here!
提示/dev/sdb5 正在被使用。 /dev/sdb5 正在被DM管理,所以我们创建文件系统时提示报错,我们手工的移除,就可以正常的创建文件系统,操作如下:
[root@hpf-linux~]# cat /proc/partitions
major minor #blocks name
8 0 20971520 sda
8 1 204800 sda1

253 4 2104483 dm-4
从上面可以看到dm工具确实在用。
