Barns and Warehouses can store much more than 10k in total. You just need to keep upgrading them :)

20 lvl barns and warehouses can store 210 000 rss of each types.

But therer are several restroctions in upgrading - you storage buildings can't be more lvl than Keep. So just upgrade your Keep an then everything else =)

Really stuck badly since long to upgrade the Crystal Vault to level 10. The required RRS is above 33000 each, but the warehouse and barn cant be upgrade to store more then 10000 Resource.

tried all level stil cant able to upgrade it. 

any suggestion on how to do it.

I ran into the same "gotcha" a while back. What you think requires a Crystal Vault upgrade actually requires a House of Scrolls upgrade. The icons for those two structures look similar and is easy to confuse between them. Upgrade the "House of Scrolls" and your problem is resolved.
