虚拟机下扩展Linux的磁盘空间

1、虚拟机下扩展Linux的磁盘空间首先在vmware当即的情况下扩展空间；启动Linux，然后执行parted命令：|口口 区bcigcin . = pstLsdCiXC Fa心d 1.8.1使用 /cic v/sia1 come Lo (iMU Ps/Lcl!

10、lume LogVol00 successfully resized rootbogon #9,此时加好后还不会生效，还要执行一条命令：rootbogon # resize2fs -p /dev/VolGroup00/LogVol00resize2fs 1.39 (29-May-2006)Filesystem at /dev/VolGroup00/LogVol00 is mounted on /; on-line resizing required Performing an on-line resize of /dev/VolGroup00/LogVol00 to 2572288 (4k) blocks.
