I have a Koji system and a tag within it with lots of (~1000) packages. I've succesfully built all of them for i686 architecture, since it was the only set architecture.

Later I had an idea to create packages for x86_64 as well and set up the tag's architecture to i686,x86_64. Every newly built package builds fine for both architectures.

Is there any way to rebuild the ~1000 package only for x86_64 now? I tried to use 'koji create-task buildArch' but it wasn't successfull.

I even tried to cancel the builds and resubmit them, but I couldn't, since they are completed. I don't really want to do a mass rebuild, only if this is the only solution.

You can't rebuild a new architecture after the fact and have it be part of the same build entry (N-V-R) as the original. The later rebuilds are different in significant ways. The code may be the same, but the build environment is most likely not.

Your best bet is simply to bump the release and rebuild with a new N-V-R. You could do this only for x86_64 if you want (use a different build tag with a restricted arch list).
