300GB of Blockchain in dir, prune is set to 20GB #22733

I assume its just rubbish from old client versions of bitcoin core. how to identify files that are not used any more?

What is the content of the blockchain folder? Did you use txindex? bootstrap.dat? A version prior to 0.8?

./blocks is 300g and has an index dir, it has *.dat files from blk00668.dat to blk02701.dat and rev00667.dat to rev02701.dat and in /index a lot of ldb files, summing up to 105M

Did your node crash during a -reindex? What does the RPC getblockchaininfo tell you?

yes i had several crashes. getblockchaininfo brings (anonymized):

{ "chain": "main", "blocks": 696479, "headers": 696479, "bestblockhash": "<...>", "difficulty": 15556093717702.55, "mediantime": ..., "verificationprogress": 0.9999977637842665, "initialblockdownload": false, "chainwork": "00000000000000000000000000000000000000002097f1948f8882a22d0f4080", "size_on_disk": 17548713171, "pruned": true, "pruneheight": 683334, "automatic_pruning": true, "prune_target_size": 18999148544, "softforks": { "bip34": { "type": "buried", "active": true, "height": 227931 }, "bip66": { "type": "buried", "active": true, "height": 363725 }, "bip65": { "type": "buried", "active": true, "height": 388381 }, "csv": { "type": "buried", "active": true, "height": 419328 }, "segwit": { "type": "buried", "active": true, "height": 481824 }, "taproot": { "type": "bip9", "bip9": { "status": "locked_in", "start_time": 1619222400, "timeout": 1628640000, "since": 687456, "min_activation_height": 709632 }, "active": false } }, "warnings": "" }

so i assume it has forgotten about 330g on disk?

please close, i deleted the data dir, the hd had an issue too, so i dont know if the issue is interacting with hd errors.
