This is my setup with a Harddrive of 1TB capacity and one lvm partition with the size of around 100GB on it. Within the LVM there is a NTFS drive containing Windows.

I'd like do resize the NTFS drive within the LVM to give Windows more space without damaging Windows.

Thank you for your time.

You can resize logical volumes with the lvresize command. Assuming you are using the LV as the virtual disk for a VM, windows will then think the drive has grown, and will have unpartitioned space on it. You should then be able to use the Windows disk manager to expand the partition.

After I added an existing physical volume via vgextend to the volumegroup lvresizedid the job and everything worked like a charm. Thank you a lot! – gro Nov 24 '12 at 13:02
