ESXI4.1 linux虚拟机调整扩充磁盘大小
首先调整磁盘大小为60G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 shutdown -r now
fdisk -l

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)
