how to go about resizing the virtual disk?
Hi guys ,
We are running machines in virtual environment.
As a part of virtual solution we have a disk created in form of files on host machine.
The problem is we are facing space crunch and need to re size the harddisk files of virtual machines.
There a catch the virtual machines are running linux and using LVM so resizing the actual hardisk file with dd is not an option(correct me if i m wrong) .I guess i have to first reduce the LV and then create some un partitioned space on virtual machines file system .
Any help would be appreciated.
