错误以下：node
[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，因此咱们建立文件系统时提示报错，咱们手工的移除，就能够正常的建立文件系统，操做以下：
linux
[root@hpf-linux~]# cat /proc/partitions major minor #blocks name 8 0 20971520 sda 8 1 204800 sda1 8 2 5120000 sda2 8 3 2048000 sda3 8 4 1 sda4 8 5 13596672 sda5 8 16 20971520 sdb 8 17 5253223 sdb1 8 18 2104515 sdb2 8 19 3156772 sdb3 8 20 1 sdb4 8 21 2104483 sdb5 8 32 18874368 sdc 253 0 5253223 dm-0 253 1 2104515 dm-1 253 2 3156772 dm-2 253 3 1 dm-3 253 4 2104483 dm-4
从上面能够看到dm工具确实在用。
bash
