But had some other things to take care of first. In my case I don't have separate / and /home. So, I am going to decrease / and increase swap. Decreasing is more dangerous than Increasing. You'll be decreasing /home and increasing /. This is the system normally booted before modification.

So, I then boot from the F31 Mate Spin image and do the following. [root@localhost-live ~]# e2fsck -ff /dev/fedora_localhost-live/root e2fsck 1.45.3 (14-Jul-2019) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/fedora_localhost-live/root: 226041/1114112 files (0.2% non-contiguous), 1855851/4455424 blocks I now resize the filesystem to 15GB. Failure to resize the FS will result in disaster.

The filesystem on /dev/fedora_localhost-live/root is now 3932160 (4k) blocks long. Make the LV inactive [root@localhost-live ~]# lvchange -a n /dev/fedora_localhost-live/root Now, shrink the LV....but not as much as the FS. I can't recall the reason for this....but that is what I've done in the past. 0.5 difference is probably excessive but....

Logical volume fedora_localhost-live/root successfully resized. Activate the LV [root@localhost-live ~]# lvchange -a y /dev/fedora_localhost-live/root And run a check on the new size [root@localhost-live ~]# e2fsck -ff /dev/fedora_localhost-live/root e2fsck 1.45.3 (14-Jul-2019) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/fedora_localhost-live/root: 226041/983040 files (0.3% non-contiguous), 1846611/3932160 blocks Then I want to increase swap. But I intentionally make it too big to find out what is really available. This is where you'd increase /. [root@localhost-live ~]# lvresize /dev/fedora_localhost-live/swap -L 4GB Insufficient free space: 512 extents needed, but only 383 available So then I do this. In this case I'm adding extents rather than giving a specific size.

Logical volume fedora_localhost-live/swap successfully resized. I then boot normally and see.
