我有一个CentOS系统，有508G的可用空间。我想从中创建一个新分区。它位于扩展分区中。
我创建新分区并将其格式化为任何格式（ext4、fat32），应用后它无法完成该过程并给出以下错误：
An error occurred while applying the operations

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.
当我保存它时，save_details.htm它包含以下信息：

========================================
我使用 fdisk 并创建了/dev/sda6，我看到这样的分区：
$ 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
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0xa62a8bc3
Device Boot Start End Blocks Id System
/dev/sda1 * 1 262 2097152 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 262 5361 40960000 83 Linux
/dev/sda3 5361 10460 40960000 83 Linux

/dev/sda6 11480 77825 532917056+ 83 Linux
Partition 6 does not start on physical sector boundary.
但是当我使用mkfs格式化它时，我看到这个错误：
$ 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?
问题是什么？
答案1
您应该通知内核对磁盘所做的更改。为此你需要运行partprobe.
# partprobe /dev/sda6
然后您应该运行mkfs.ext4将文件系统分配给新创建的分区。
# mkfs.ext4 /dev/sda6
这样你的分区就准备好了mount
# mount /dev/sda6 /mountpoint
答案2
partprobe -s执行任何操作之前必须先运行该命令/dev/sda6
如果您没有该命令，只需重新启动机器即可
答案3
您需要移动/重新创建 Linux 交换分区并确保它在柱面边界上开始/结束
答案4
我的建议：您应该尝试使用 fdisk /dev/sda 添加新分区。有时 gparted 会遇到此类问题。
