Our discussion in my earlier post formed much of this post so thanks again for sharing everything!
So I'm one folder deeper in _data/steem/ running this command specifically:
# du -sh _data/steem/
419G _data/steem/
I'm also surprised I'm at 419GB (already up 2GB!) and you're at 388GB so here's the exact tables that are at least a GB in size.
# ls -lh _data/steem/ | egrep '[0-9]G'
total 419G
-rw-r-----. 1 polkitd ssh_keys 255G Mar 1 21:43 sbds_core_blocks.ibd
-rw-r-----. 1 polkitd ssh_keys 1.5G Mar 1 21:43 sbds_tx_claim_reward_balances.ibd
-rw-r-----. 1 polkitd ssh_keys 77G Mar 1 21:43 sbds_tx_comments.ibd
-rw-r-----. 1 polkitd ssh_keys 25G Mar 1 21:43 sbds_tx_custom_jsons.ibd
-rw-r-----. 1 polkitd ssh_keys 2.5G Mar 1 21:43 sbds_tx_transfers.ibd
-rw-r-----. 1 polkitd ssh_keys 57G Mar 1 21:43 sbds_tx_votes.ibd
I don't have a good explanation for why we'd see different sizes, so I'm pretty curious about this.
