i installed and configured RBS following this and did it with no error, but if i upload a big file it doesn't go to Blobstore folder or it's RBSID in database ( DocStreams) is null, means that it stored in content database, i have no idea where to start troubleshooting, so any advice will be helpful.
PS: in following that article i have two dark point, that might cause the problem .
1: install the RBS client library on all additional web and application servers; i have two server, one for SQL and SharePoint (which i install RBS on that) and one for Domain controller, so is it needed to install RBS on DC?
2: i don't now much about permissions and did all of configuration with SP system account. where can i check if the problem could be from permission?
