Title: 2 databases?
Post by: opentoe on February 19, 2014, 07:38:07 PM
Does Armory need both huge databases? The original bitcoinD's database, and Armory's itself? I think both combined comes to about 60GB of data.

Delete please.

This is the cost of having a highly secure Bitcoin client. If convenience is more important for you, there are several light clients available where you can rely on others to keep an accurate block chain.

Your estimate is about 20GB too high.

Also, Armory's database can be reduced, but 0.90-beta was a pretty huge overhaul of the block data engine, and it was easiest to just duplicate it.  Hopefully by 0.92-beta we'll be able to scale it down in size by an order of magnitude, and rely on bitcoin-qt to provide any data we might occasionally need that's not in the Armory DB.

Until then:  yes, you need two copies.

If you have 60 GB, it's possible that you have double blockchain data because you tried dumping the blk*.dat files into an existing Bitcoin-Qt/bitcoind isntance, and it redownloaded the chain on top of it instead of bootstrapping off of it (I've seen a lot of people make that mistake, myself included).  It sounds like a possible reason for your current situation, since it's almost exactly twice as big as it should be.
