I'm trying to expand my rootfs to the 64Gb size of my micro SD card on Raspbian Jessie, on a RPi3. The initial attempt by
raspi-config to resize the filesystem seems to succeed and it prints the
Resized filesystem rebooting in 5 seconds
message. However upon reboot the size is still 4.5Gb using the
df -h command.. An external Linux PC which saw the volume as 4.5Gb before the initial resize now sees it as 62.5Gb, so supposedly the resize did succeed. No matter how many times I reboot on my RPi though I still see 4.5Gb. I did read that the max supported SD size is 32Gb, but it seems unlikely that this would cause the size to appear as 4.5Gb while the card works properly in general. Of course I could be wrong here, so any ideas on what's going wrong would be really appreciated.
