modifying growpart to not capture sfdisk output, I saw:
Checking that no-one is using this disk right now ...

This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
BLKRRPART: Device or resource busy

So, somehow the partition or disk is seen as busy.
