To save space, I create base disk images of clean OS installs on a minimalistic sized disk. If I need space, I use tools from VMWare to make the virtual disk bigger, and then grow the bits inside Linux with LVM. I used the following two documents for info: http://fedoranews.org/mediawiki/index.php/Expanding_Linux_Partitions_with_LVM http://www.knoppix.net/wiki/LVM2 In my case, I was growing the root filesystem, so I needed to boot into something like Knoppix (hence the 2nd link above). To summarize the links...(usual caveats, backup data, etc, etc) -Create a new partition of type 8e (Linux LVM) on the new empty space. -Add that pv to LVM If the new partition is /dev/sda3, then this would look like pvcreate /dev/sda3 -Extend the volume group that contains the logical volume you want to add this space to If the the VG is VolGroup00 then vgextend VolGroup00 /dev/sda3 -Here I usually run vgdisplay, and get the amount of free disk space that now exists. (Look for the line that says Free PE / Size) If the Free PE / Size says there are 2.2GB free and the LV is LogVol00 you could do lvextend -L+2.2G /dev/VolGroup00/LogVol00 -Extend the filesystem. For ext2/ext3, use resize2fs (you may want to fsck before this, this is with the filesystem unmounted) resize2fs /dev/VolGroup00/LogVol00 -Fsck e2fsck -fy /dev/VolGroup00/LogVol00 (you may now want to use -y) The trick I had when doing this in Knoppix for existing LVMs was after fdisk'ing to run vgscan; vgchange -a y to get the existing LVM partitions recognized and /dev entries created. -Shawn
