Erigon v3: old data not available due to pruning

[fridary]

Erigon version: 3.00.0-beta1-0b94461f
OS & Version: Debian 6.1.119-1 (2024-11-22) x86_64, CPU E5-2695 v4, 36 cores, 192 Gb RAM
Disk: NVMe HPE MT006400KWHAE 6.4 Tb
Erigon Command (with flags/config): /root/erigon/build/bin/erigon --datadir=/disk_nvme/erigon --ws --http.api=eth,erigon,engine,web3,net,debug,trace,txpool --authrpc.jwtsecret=/root/erigon/jwtsecret --torrent.download.rate=512mb --rpc.batch.limit=5000

I do simple rpc request to block 21431353 (50 days ago) and get error {'code': -32000, 'message': 'old data not available due to pruning'}
How to modify Erigon command to get fully archive node for all time? No pruning. I can't find docs about it for v3.

@fridary You need to set --prune.mode archive: see https://github.com/erigontech/erigon?tab=readme-ov-file#erigon3-changes-from-erigon2
