I believe you can sync OK now, but a comment on this command line.
rsync's -h option is "output numbers in a human-readable format". While that may be nice for logging purposes and such, I would recommend adding the -H option as well. -H is "preserve hard links", which is particularly useful at point release times.
For a slightly simplified example, 6.9's rpms take up around 8 GB of disk space. The updated packages in the upcoming 6.10 take up around 1 GB. If your rsync does not use that -H option, you will need to download around 8 GB of 6.10 packages when 6.10 gets released. If you have -H enabled, you will need to download only that 1 GB of fresh 6.10 packages. The remaining unchanged packages (around 7 GB) will be hard linked between 6.9 and 6.10, and transferring this hard link information is very quick.
Each hard linked file needs to be stored on disk only once, saving you some hard disk space.
If you (or any others reading this message) don't have -H in your rsync command line, please add it. The next time you sync your mirror, rsync will remove the duplicate files and create hard links for them.
In certain rare situations the underlying file system does not understand hard links. In this case the -H flag won't help.
