custom yum repo not showing rpm - centos

Question

I have a yum repository I've set up where I store custom rpms.
I have no problem finding information about other packages that were built and stored in this custom repo.
#yum --disablerepo=rhui-us-east-rhel-server-1y,epel,epel-testing --enablerepo=customrepo install php53-pecl-xdebug
php53-pecl-xdebug x86_64 2.2.1-2 customrepo 132 k
No problem.
Now I drop somerpm.rpm in centos/repo/5/noarch, run createrepo --update . in this directory and try the same command, and yet it shows no results.
I tried running createrepo --update in the root of the repo as well, but that did not work either (I'm actually not sure where to run it and if it needs a repodata directory in each subdir).
[root#reposerver mnt]# ls -l /var/www/repo/
total 12
-rw-r--r-- 1 root root 203 Jun 8 00:13 REPO_README

-rw-r--r-- 1 root root 14294 Oct 18 19:54 salt-minion-0.10.3-1.noarch.rpm
I also tried adding the exactarch=0 flag to my repo config to ignore arch restrictions and this did not work either, it was a shot in the dark, since my rpm is noarch, it should show regardless.
# cat /etc/yum.repos.d/mycompany.repo
[mycompany]
name=mycompany custom repo
baseurl=http://config/repo/centos/5/$basearch
enabled=1
exactarch=0
I'm at a loss at this point. Usually createrepo --update does the trick, but for some reason it cannot find the new rpms.
repo]# find . -type f -name "*.gz" | xargs zcat | grep salt-minion
returns results as well, so it's definitely in the repo data.

Answer 1

yum clean all on the server I was trying to install on worked.
Also make sure to do createrepo --update on the specific subdir instead of the root of the repo.
