無法創建新分區

我有一個擁有 508 G 可用空間的 CentOS 系統。我想從中創建一個新分區。它位於擴展分區中。

我創建新分區並將其格式化為任何內容（ext4，fat32），應用後它無法完成該過程並給我這個錯誤：

An error occurred while applying the operations
See the details for more information.

IMPORTANT
If you want support, you need to provide the saved details!
See http://gparted.sourceforge.net/larry/tips/save_details.htm for more information.

當我保存它時，save_details.htm它包含以下資訊：

GParted 0.6.0

Libparted 2.1

========================================

我使用 fdisk 和 created /dev/sda6，我看到這樣的分區：

$ sudo fdisk -l 

Disk /dev/sda: 640.1 GB, 640135028736 bytes
255 heads, 63 sectors/track, 77825 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Partition 6 does not start on physical sector boundary.

但是當我mkfs用來格式化它時，我看到了這個錯誤：

$ sudo mkfs -t ext4 /dev/sda6
mke2fs 1.41.12 (17-May-2010)
Could not stat /dev/sda6 --- No such file or directory

The device apparently does not exist; did you specify it correctly?

問題是什麼？

您應該通知核心有關對磁碟所做的更改。為此，您需要執行partprobe.

# partprobe /dev/sda6

然後您應該執行mkfs.ext4以將文件系統分配給新創建的分區。

# mkfs.ext4 /dev/sda6

這樣你的分區就準備好了mount

# mount /dev/sda6 /mountpoint

partprobe -s您必須在執行任何操作之前執行該命令/dev/sda6

如果您沒有該命令，則只需重新啟動機器
