64GB SD card but unable to update to 4.1 due to space issues?

hey guys

so swtched on my arcade box today for recalbox to tell me 4.1 was available when through the update process and it rebooted and my controls no longer worked (still on 4.0.2) plugged keyboard in and that worked. SSH in to try update and get the following error

Cannot write to '/recalbox/share/system/upgrade/root.tar.xz.part' (No space left on device).

df -h gives the following:
Filesystem Size Used Available Use% Mounted on
/dev/root 1.9G 1.0G 747.9M 59% /
devtmpfs 236.7M 0 236.7M 0% /dev
tmpfs 240.9M 0 240.9M 0% /dev/shm
tmpfs 240.9M 4.0K 240.9M 0% /tmp
tmpfs 240.9M 2.8M 238.1M 1% /var
tmpfs 240.9M 140.0K 240.8M 0% /run
tmpfs 128.0M 122.7M 5.3M 96% /recalbox/share

now the thing is its a 64gb sd card (original image was smaller but then placed on a bigger card)
so i thought maybe i just need to edit the partition with gparted.

Thing is Gparted shows that theres space on the share partition see pic attached

any ideas?
