I needed extra space on my /boot partition so I took the SD card, inserted it into my PC and expanded/moved the partitions using GParted (this to my surprise took over 4 hours to complete).

pi@raspberrypi:~ $ df
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/root       25660524 1777960  22815436   8% /
devtmpfs          470176       0    470176   0% /dev
tmpfs             474784       0    474784   0% /dev/shm
tmpfs             474784    6360    468424   2% /run
tmpfs               5120       4      5116   1% /run/lock
tmpfs             474784       0    474784   0% /sys/fs/cgroup
/dev/mmcblk0p1     41976   29357     12619  70% /boot          # 41 MB

pi@raspberrypi:~ $ lsblk
NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0 28.9G  0 disk
├─mmcblk0p2 179:2    0 24.9G  0 part /
└─mmcblk0p1 179:1    0    4G  0 part /boot                     # 4 GB

As you can see lsblk shows the boot partition to be 4 GB, but df reports it's 41 MB (that was its size before I expanded it). Also writing files larger than the free space df shows doesn't work.

How do fix my /boot (mmcblk0p1) partition so it's correctly expanded to 4 GB?

It seems the partition has the expected size, but not the file system on it. Perhaps gparted has failed that last part and you have not noticed it.

First of all, you should run fsck.vfat on this partition, because it seems they were a problem the first time you tried.

Then I would recommend to either retry with gparted or using fatresize.

It should take a much shorter time since the data from the second partition will not be moved this time.
