漂泊的云,停留的心!人的头脑太复杂,时间过得久,有时候连自己也被自己骗了,记下来才是最真实的……

Ubuntu18.04下无法格式化硬盘/dev/sd* is apparently in use by the system; will not make a filesystem here!


环境说明:ubuntu 18.04 Lts
问题说明:新装的Linux系统,两块硬盘,一块作为系统磁盘,另一块作为数据磁盘,安装完系统后,由于该数据磁盘中包含之前残余的LVM信息,无法对数据磁盘无法进行操作。

新系统启动后,通过fdisk -l查看磁盘信息如下

[root@ovirt-host ~]# fdisk -l

对sdb1进行格式化,无法进行格式化,提示如下

[root@ovirt-host ~]# mkfs.ext4 /dev/sdb1
mke2fs 1.41.12 (17-May-2010)
/dev/sdb1 is apparently in use by the system; will not make a filesystem here!

解决方法:

通过dm解决问题,查看dm状态,显示dm设备信息

[root@ovirt-host ~]# dmsetup status
3600508e00000000017cd3aa6870c460a: 0 1952448512 multipath 2 0 0 0 1 1 A 0 1 0 8:16 A 0 

删除dm信息,并再次查看dm状态信息

[root@ovirt-host ~]# dmsetup remove_all
[root@ovirt-host ~]# dmsetup status
No devices found

此次dm已经找不到设备,再次通过fdisk查看磁盘信息,已经没有dm设备信息了

[root@ovirt-host ~]# fdisk -l;

Disk /dev/sda: 999.7 GB, 999653638144 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda3            4211      121535   942406656   83  Linux

Disk /dev/sdb: 999.7 GB, 999653638144 bytes
255 heads, 63 sectors/track, 121534 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1      121534   976221823+  83  Linux

此时在对sdb1进行格式化操作

[root@ovirt-host ~]# mkfs.ext4 /dev/sdb1
meta-data=/dev/sdb1              isize=256    agcount=4, agsize=61013864 blks
