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.

virtual-filesystems

virtual-filesystems(7)					 Miscellaneous Information Manual				    virtual-filesystems(7)

NAME

       virtual-filesystems - event signalling that virtual filesystems have been mounted

SYNOPSIS

       virtual-filesystems [ENV]...

DESCRIPTION

       The  virtual-filesystems  event	is  generated  by  the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
       mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so	in  parallel  with
       other activity.

       This event is typically used by services that must be started in order to mount other filesystems.  When this event occurs, common filesys-
       tems such as /usr may not be mounted.  For most normal services the filesystem(7) event is sufficient.

EXAMPLE

       A service that wishes to be running once virtual filesystems are mounted might use:

	      start on virtual-filesystems
