Reconfiguring Hard Disk with LVM.....to remove it.

Postby pins on Sun Jan 27, 2013 12:51 pm

Hi All

I have a setup with dual booot Win 7 and Mint Mate 13.

The Disk is a 750GB (less after overhead) with 1/3 given to Windows and 2/3 to Fed12 in a LVM setup.

I'm going too install Mint Mate 14 but need to move some data around before doing the new installs..

1. I've realised that LVM is a PITA on a single drive setup if you want to get windows to read the drives, so back to normal partitions.

2. I didn't need so much space for Windows, I do need more shared/common space.

So I recovered 160GB from the Windows partition using Gparted.

I also recovered 200GB from the LVM partition using LVM tools.

I've now hit two different problems.....

My partition info is....

1. Standard Win installed 100mb system, I'll be deleting this on the rebuild.

2. Win7 70ish GB Parition with OS, Apps and Data.

3. Linux Boot partition 1GB

4. Now unused/unallocated 160gb recovered from Windows partition 2 earlier.

5. Extended

6. LVM partition for rest of drive, 200GB unused that I want to recover.

First problem is

The 200GB in the LVM is split into three segments even though it's only one ext4 partition (and was originally setup this way) and I can't find a way to join the segments, as a result I can't reduce the LVM size and release the 200GB usused space.


Second problem is that
The other 160GB (4 above) unused is in the primary space so I can't create a new partition and I can't move the extended partition to the left to make the space at the end.

I don't have any other disks sitting around and need to do this tonight.

So at the moment I have a 750GB drive with about 360GB free space that I can't access.

What I want to do is create a 350ish GB partition at the end of the drive to move data/stuff to before I do the rebulds then move it back and then recover that space using gparted later.

My proposed interim partition setup..

1. Windows 7 Boot say 70GB.

2. Linux Boot Partition. 1GB

3. Linux Primary Partition say 100GB (I now prefer all home, root / etc in this partition)

4. Swap 8GB

5. Extended

6. Shared space empty around 200GB

7. Current empty space 350GB ish, being used as temp storage.

FInal proposed setup

1. Windows 7 Boot say 70GB.

2. Linux Boot Partition. 1GB

3. Linux Primary Partition say 100GB (I now prefer all home, root / etc in this partition)

4. Swap 8GB

5. Extended

6. Shared space around 550GB

Any ideas or suggestions gratefully recieved.
