Abnormal disk space growth with `--prune.mode=minimal`

[alexdupre]

System information

Erigon version: 3.3.0 (but the node started with 3.2.0)

OS & Version: Ubuntu 24.04

Erigon Command (with flags/config): erigon --prune.mode=minimal

Chain/Network: ethereum

Expected behaviour

Disk usage below 400GB after sync, very slow increase over time.

Actual behaviour

~355GB disk usage after initial sync, 1.1TB after 2 months.

I haven't the breakdown for the initial status, but this is the current one:

268G    ./caplin
12K     ./migrations
32K     ./downloader
22M     ./nodes
415G    ./chaindata
1.1G    ./temp
410G    ./snapshots
193M    ./txpool
157M    ./logs
1.1T    .

[Giulio2002]

you can rm -rf chaindata to clean up space

@Giulio2002 Can you expand a little bit, please? Why may I delete it? And why is it growing so fast? Shouldn't the --prune.mode=minimal flag keep the storage requirement low?

Re-opening because running a node shouldn't require manual interventions like chaindata removal. Might be related to #17891.
