linux没有sdb文件夹,linux – mkfs抱怨说：“/ dev / sdb显然是系统使用的;不会在这里制作文件系统“...

这是Ubuntu服务器11.10.

/ dev / sdb未挂载(请参阅下面的输出),并且我没有看到任何进程使用它.它也不用于交换.这是服务器中的第二个IDE驱动器,连接到辅助IDE,并在硬件raid中设置为阵列2.

我无法安装驱动器,因为我可能已经在使用它.我确实运行了fdisk,删除了所有以前的分区并创建了一个主分区.

/dev/sdb is entire device, not just one partition!

Proceed anyway? (y,n) y

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