请教大家个问题，在FC6下做LVM时候产生个问题，我在装LINUX时候就分了两个区，/dev/hda1 挂在了/下，/dev/hda2挂在了/usr/local下，剩下的容量我在进入系统后利用fdisk 分的，错误产生如下，请大家多帮小弟看看。
[root@localhost ~]# fdisk -l

[root@localhost ~]# fdisk /dev/hda
The number of cylinders for this disk is set to 1044.
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)
