ArweaveTeam/arweave N.2.6.1

Release 2.6.1

on GitHub

The release introduces a convenient way to copy and repack data across the local storage modules, including the legacy 2.5 storage.

Some hightlights:

• the data is copied and repacked from the 2.5 storage to the corresponding storage modules, if any, and between the storage modules; once finished, the node attempts to sync the missing data from the network;
• additionally, the 2.5 data is repacked in place when the node is launched with enable legacy_storage_repacking;
• the broken chunk index records are repaired in the process;
• the limits for the number of chunks to keep in RAM (by the syncing, packing, and mining processes accordingly) are chosen based on the available memory and reported on startup; the limits may be overriden via data_cache_size_limit [number], packing_cache_size_limit [number], and mining_server_chunk_cache_size_limit [number];
• the estimated maximum packing rate is reported on startup (you might want to restart the node with packing_rate [number] afterwards.

The release comes with the prebuilt binaries for the Linux x86_64 platforms. arweave-2.6.1.linux-x86_64.tar.gz works on Ubuntu 21+ and CentOS 8. To run on Ubuntu 18 or 20, grab arweave-2.6.1.ubuntu18-x86_64.tar.gz or arweave-2.6.1.ubuntu20-x86_64.tar.gz . CentOS 7 is not supported.

If you want to run the miner from the existing Git folder, upgrade Erlang to version 24 and execute the following command:

git fetch --all --tags && git checkout -f N.2.6.1
