GParted won't reduce partition size


The Issue

As I screwed my linux install (the home folder is encrypted and through a series of unfortunate events, I know cannot decrypt it) I want to make another partition on the HDD and install linux mint to that partition, so I don't have to work from a live USB anymore. However, GParted won't resize the partition.

I Tried

I started GParted from the start menu, selected the prober hdd, and hit 'move/resize'. However, it says the minimum size is ~900 GB (almost the entire hard drive) even though there's only around 100GB used (which is what the file system shows me). Therefore, I can't decrease the partition size, even though it should be mostly empty.

I tried running GParted as root, to see if that helps, but the terminal gave the below response.

Code:
sudo gparted

I have tried to find a solution through DuckDuckGo, as well as the search on this forum, but I have been unsuccessful. The tutorials I find, all show the partition with unused space, but my GParted shows it is used almost entirely, with only 12 MiB unused.

Any help would be much appreciated, as I really don't want to format the entire HDD, because I still have hope of getting access to the encrypted folders which hold quite some files I can't easily replace (KeePass database, work-related stuff, research material and articles I wrote. There's many days of work in there).

relevant info

I'm running Linux Mint 17.2 on an external HDD, as my internal HD died months ago. It's the XFCE edition of Mint. I've been using Linux for around 6-8 months, so I have working knowledge of the terminal and most of the software on here, but I am not very familiar with the underlying workings of the OS.

Edit:
I just noticed the partition has an LVM flag. I imagine that could have something to do with it, but I don't know how this applies to the actions I have to undertake. I'll be looking for a solution and updating this question if I find anything. In the meantime, any help is still highly appreciated.

The above comment would indicate to me that you are running GParted from an installed system. You can't modify partitions from a running system that is mounted. It's always simpler to use GParted from the installation medium if you have it and Mint does. You could also download GParted and put it on a bootable CD. You need to unmount any partition before you resize or try to modify it in any way.

I don't use LVM but I think you can do it with a newer version of GParted. Check the link below or do an online search for "resize lvm partitons with GParted".

I'm running it from a live USB with Linux Mint 17.2

I can't see your link, but I'll see what else I can find.

Thanks for your input so far!

I managed to resize the LVM partition using system-config-lvm as outlined here: http://askubuntu.com/questions/19612...hysical-volume

Now at least GParted shows the partition as having unused space. However, when I now try to resize the partition down to the amount of space it actually uses, I get the below result.

What am I missing here?

Code:
GParted 0.18.0 --enable-libparted-dmraid --enable-online-resize

If you know you can't use the data currently on the disk, don't bother with resizing. Just delete the partition and add a new one.

Turned out there was a swap partition at the end of the logical volume. Deleted it, recreated it, tried to resize again, success!

Now to create the new partition for my new install, and one for my files. If all goes well, I'll list the thread resolved.
