Warning: WARNING: the kernel failed to re-read the partition table on

of your changes until after reboot.
I thought the intent was to avoid such warnings when they do not apply.
The kernel was indeed notified of the creation of the two new
partitions, and I was able to create file systems on them.
Do you have an active LVM on a partition on the drive?
If so then that might be the reason why the warning is encounted.
Having an active LVM on a partition is similar to having a mounted
partition in that the partition is busy. I think that parted fails to
detect active LVM partitions as being busy.
This problem was first brought to my attention by a GParted user.
GParted fails to edit/delete partitions if active LVM on same disk device
