One additional comment: The problem is NOT solved by rebooting. It seems that zeroing out is necessary :-(

Are you sure you have the same config as I (RAID1)?
Only in this case my howto makes sense, otherwise you will destroy all your data!!

If you are sure (really sure!) then the disk in the command must match:

 cat /dev/zero | pv -s 3000G | dd of=/dev/sdb bs=100M

I think your can skip the zero-ing part. Unless you have write-intent bitmaps enabled, then just removing and re-adding a drive will cause MD to overwrite the entire disk, including your pending-bad blocks. Thiis has worked for me many times. Remember, though, that the SMART Offline_Uncorrectable won't get updated until the next offline collection occours, like with smartctl -t offline.
