"잘못된 블록 수"로 인해 ext4 파티션 생성이 실패함

환경: - VMWare ESX 4.0의 가상 머신 - OS: 최신 RHEL 5.8

새(가상) 디스크를 추가한 후 이 디스크의 LVM에 ext4 파티션을 생성하고 싶습니다.

지금까지 취한 조치:

$ 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)

Command (m for help): n
p
Partition number (1-4): 1
First cylinder (1-10443, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-10443, default 10443):
Using default value 10443

Command (m for help): t
Selected partition 1
Hex code (type L to list codes): 8e
Changed system type of partition 1 to 8e (Linux LVM)

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.

ext4 파티션을 생성하지 못했습니다:

$ sudo /sbin/mke2fs -t ext4 /dev/VGora/oradata

이 오류에 대한 관련 정보를 찾을 수 없으며 해결 방법도 모르겠습니다.

• 블록 수는 어떻게 확인하나요?
• ext4에 유효한 숫자로 어떻게 수정합니까?
