Here is an article on the recovery disc space in the complete bitcoin node:
complaint disk space in bitcoin core full node
As an operator in full node, the maintenance of the complete state of the core Bitcoin node can be a significant task. One of the major challenges is to keep the disk space occupied, which can lead to slower performance and increased energy consumption. In this article, we will explore some strategies to recover the disk space in your complete Bitcoin node.
The current state
Before immersing yourself in solutions, let’s take a look at our current situation. We have some batteries: Bitcoin Core + Fulcrum with full knot. As you said, because of the fulcrum, we use txindex as a pruning node, which means that the disk space is not used for its planned purpose.
The problem
The use of TXindex can consume a significant amount of disk space, especially if it is not correctly optimized. The default configuration of TXindex often translates into a huge index file, which can occupy a substantial part of our disk. This can lead to slow performance, synchronization of the slowest node and increased energy consumption due to the constant i/o disk operations.
solutions
Fortunately, there are several ways to recover the disk space in your complete bitcoin node:
1.
Optimizes the TXindex configuration
One of the most effective ways to reduce the use of TXindex is to optimize its configuration. This entails the setting of optimal values for the following parameters:
txindex.target ': Sets this parameter on a lower value, like 3. This will allow the pruning node to prune the knots in a more aggressive way.
txindex.max_index_files: Increase this limit to ensure that the size of the index file is not too big.
txindex.weep_ interval_ms: decrease this interval to reduce the frequency of pruning.
2.
Use a personalized pruning node
If you don’t want to rely on TXindex, you can use a personalized pruning node. This involves setting a separate node that performs the same function as TXindex but with some applied optimizations. It is therefore possible to use this new node as a pruning node and set its txindex.target 'parameter.
3.
Disable pruning
If none of the above solutions works, it may be necessary to completely disable pruning. This will require theprune_node = offin the configuration file of the core bitcoin ( ~/.bitcoin/bitcoin.conf). However, keep in mind that this can lead to a synchronization of the slower node and an increase in energy consumption.
4.
Use a different index file format
Another solution is to use a different index file format which is more efficient than thejsonindex.binpredefinito used by txindex. For example, you can try to use a newer format such asKVDB_INDEXO KVDB_1.2. This can request an experimentation and modification of the configuration.
5.
Clean Row Files
To maintain optimal performance and reduce the use of disk space, it is essential to regularly clean the index files that are no longer necessary. It is possible to use tools such asBitcoin-Cli` or a dedicated indexing tool to periodically remove the old index files.
Conclusion
The recovery of the disk space in the complete Bitcoin Core node requires an experimentation and the modification of the configuration parameters. By optimizing the TXindex settings, using custom pruning nodes, disabling pruning, the attempt at alternative index file formats and regularly cleaning the index files, it is possible to improve performance and reduce the node energy consumption. Remember to always monitor the performance of your node and adjust these solutions accordingly.
