创建 ext4 分区失败并显示“无效块计数”

环境： - VMWare ESX 4.0 上的虚拟机 - 操作系统：完全最新的 RHEL 5.8

添加新的（虚拟）磁盘后，我想在此磁盘上的 LVM 上创建 ext4 分区。

迄今为止采取的步骤：

$ sudo /sbin/fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.


The number of cylinders for this disk is set to 10443.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

我找不到有关此错误的任何相关信息，也不知道如何解决此问题。

  • 我如何检查块数？
  • 如何将其更正为 ext4 的有效数字？

答案1

我认为在参数解析中检查错误会导致该消息。 RHEL 5 上的 mke2fs 版本不支持该-t type参数，因此它以某种方式将/dev/VGora/oradata路径解析为最后一个（可选）块计数参数。

无论如何，您想要执行此操作的方法是确保已e4fsprogs安装然后使用mkfs.ext4 /dev/VGora/oradata或mke4fs。

答案2

mkfs.ext3 -f /dev/sdb5
mkfs.ext3: invalid fragment size - /dev/sdb5

-f当我尝试没有它的工作时，它在 RHEL5 中无法工作。

mkfs.ex3 /dev/sdb5 

mkfs.ext3 /dev/sdb5
mke2fs 1.39 (29-May-2006)
