You aren't doing anything wrong. What you see is normal and correct.
The messages

Code: Select all

Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

is because the kernel can't update its internal partition table to match the one on the disk because it is currently using it.

That's why the next step will be to do a reboot. The kernel will then read the new partition table and you'll be able to do the next step of expanding the file system.
