Fedora Hardware :: Resize A Logical Volume Group Partition?

Ok so I have one drive. /boot /lv_root and /lv_swap

At the end of the drive I have 32 gigs of free space still contained in the logical volume group. I want to remove it from the LVG but this is on one device. Supposedly there is a way to do this, pvresize and fdisk.

Good.

That's normal. pvresize "just" updates the PV header and VG metadata.

#So I guess the partition table has to be modified somehow?

Yes. That was mentioned in my reply: "Then shrink the partition in the partition table."

You can use fdisk or any other partition table editor for this. Some don't support resizing a partition. In that case, you can delete and create a smaller one. If doing the delete/create dance, you *must* create the new partition on the same cylinder boundary as the current one to preserve the current data.

Ive read from every source on LVM its not possible to do this. Why on earth would any Linux developer put LVM on a single drive system by default? Were they even paying attention? I dont mean to go off on a rant but if there are multiple drives LVM makes sense. However if you only have one large drive LVM holds your system hostage and you have to crawl thru the pit of hell to get it back.

I understand you have a choice in the matter when you install Fedora but its really the worst possible choice for default. Many newcomers to Linux run into this problem with LVM. If you cannot resize LVG's the software should have never been put into a Linux distro in the first place.
