Problem with the created Logical Volume

[kbmkris]

Hi all,

I have dual booted configuration with Fedora 12 and Windows XP running. I have reinstalled Fedora 12 yesterday as something (I don't know) gone wrong and I was not able to login into either Fedora or Windows. While installing Fedora 12 has taken a full free partition (with 100 GB) as logical volume for root, which I haven't noticed at that time. Later I have reduced this logical partition for root as 30GB and remaining space is left unused. I have two questions now.

1) Is there anyway, I can free up this unused logical volume space and add it to the uninitialized entity, so I can use it windows?

2) After installation, I had logged into Windows network, where a Found new Hardware wizard for generic volume keeps on popping up. It's really annoying to have it popped up again and again. I have raised this here as I want to know is there anything from Fedora I can do to avoid this.

Kindly let me know if you need any other details. I am a novice in Linux.

I'm not expert with lvm, but maybe you need to resize your phyical volume to 30GB. And format the rest of the partition with fdisk.

man pvresize

Whats the output of:

fdisk -l
