    i currently have created a "growable" win 2003 server guest

    the hyper-v host has 300GB available on the host disk where  the win 2003 image/guest resides

    the guest has 1 partion (c) that has about 30mb available

    i am trying to restore a sql server db (300mb) and there is a pre-requistite space check that occurs

    it indicates there's not enough space avail to restore the db

    any ideas .. i thought the "growable" property for the guest image would handle something like this

    regards

    Now sure what you mean by "growable".

    If you are referring to using Dynamic VHDs - when one is created it has a declared limit to how large it can become.

    If that limit is larger than the physical volume the VHD is stored on, folks run into problems.

    At the same time, the VHD can be edited to increase its maximum possible size - but the OS in the VM must be extended to consume this space (within the OS of the VM) - it is not part of modifying the size of the VHD.

    Hello Brian

    Thanks for the quick response .. yes "growable" refers to "dynamic vhd" ...

    the guest vhd has a limit of 125mb .. so if i edit it upwards .. will the win 2003 guest see the addition as unallocated storage ?

    if so .. shoulb be easy to extend the aprtition

    thanks

    Make sure that VM does not have any snapshots.  If it does, modifying the VHD will break it.

    power off the VM, modify the VHD - making it larger.

    power on the VM.

    open disk manager in the VM.  Extend.

    Not difficult.  Most folks have done it.
