new help resizing partitions

[Emphyrio]

I copied my music collection off my external hard drive to my main box. This apparently fille d up my hard drive. I found this hard to believe, so after investigation I find I am missing about 100 gb of space.

Running F8, default installation options. I have two sata drives, a 130GB drive (sata 0) for Windows and a 120GB drive (sata 1) for Linux/F8.

What I want to do is make this missing space available to my home directory. I assume I use GParted to do this. Trouble is, I am totally unfamiliar naming conventions etc. at his point I am not even sure I have F8 installed on the correct physical drive.

First, what tool do I use to get the information I need to resize things?

Second, are there any good (and simple) tutorials/info sheets on the way these things are organized?

**EDIT more info**

This is reported from GParted:
Partition      Filesystem     Mountpoint     Label      Size          Used      Unused     Flags
/dev/sda1      ntfs                          WINDOWS    127.99GiB     100.27GiB  100.27GiB
/dev/sda2      ext3           /boot          /boot      196.11MiB     25.57MiB   170.54MiB   boot
/dev/sda3      unknown                                  20.87GiB       ---             ---     lvm
/dev/sdb1      unknown                                 114.49GiB     ---             ---      boot,lvm

Finally, I do have all my data backed up.....so even if I screw things up and have to re-install it will only be a minor inconvienience.

Emphyrio,

Can you post the output of:

fdisk -l
mount
vgscan
lgscan

This will help determine what each drive in your system is doing and then I can give you instructions on how to extend the size of your Logical Volume.

Basically, the steps are (and associated commands):
1. Create a physical partition (fdisk)
2. Create the physical volume (pvcreate)
3. Add the physical volume to a volume group (vgextend)
4. Extend the Logical Voume (lvextend)
5. Resize the files system (resize2fs)

There is a good amount of information on LVM here.

Here is the info.

  Reading all physical volumes.  This may take a while...

Now it appears to to me that Linux/F8 was installed on a small partition on my Windows drive with only the /boot partition on the correct physical drive.

So, my first question is: Should I even bother trying to change things, or just go ahead and reinstall?

[GrapeShot]

You are correct. Linux installed on the small partition left on your Windows drive. /dev/sdb has a bootable partition on it too, but does not seem to be mounted anywhere. If you add /dev/sdb to the LVM that seems to have you linux installed on it, you would have a total of 140GB of space for linux instead of the 120GB that you have on /dev/sdb. That increase space is the only advantage though

If it were me, I would go ahead and re-install. Then I have the 20GB left on /dev/sda for some other purpose that might come up in the future.

If you decide not to reinstall, let me know and I will step you through the process of adding the drive to the LVM.

Thanks! I appreciate the help. They need to fix the installer so it reads my mind rather than the random typing I do.
