ESXI4.1 linux虚拟机调整扩充磁盘大小

首先调整磁盘大小为60G www.2cto.com

注意: 如果虚拟机做快照是无法调节置备大小的,要先删除快照才能调整

点确定后,重启虚拟机OS

The number of cylinders for this disk is set to 7832.

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)
