I have installed bitcoin-core on my digitalocean droplet and configured with the following bitcoin.conf:
datadir=/mnt/volume_name/Bitcoin
dbcache=1000
txindex=1
server=1
rpcuser=rpcuser
rpcpassword=rpcpassword
rpcport=8332
Then I start daemon, it begin to synchronize. Volume size is 500Gb, I thought it will be enough space for bitcoin blockchain, which for now is around 414 Gb. But, after a few days I realized that the volume is full!
$ df -h
Filesystem Size Used Avail Use% Mounted on
--- // ---
/dev/sda 496G 471G 4.0K 100% /mnt/volume_name
--- // ---
At the moment it stopped working and obviously it can't start again. Why does it continue to fill all space on the disk? I know it has to be some misconfiguration, but I don't understand what exactly is wrong.
There are various ways to "define the size of a blockchain".
Bitcoind likely needs multiple database indexes that multiply the space needed on the disk, as storing the raw blocks it not enough for a functional bitcoind setup.
