My IPFS node has been running all day and it's storing 6MiB according to the web UI... how come?
I've set the Gateway address in the config as such:
"Gateway": "/ip6/2a01:e34:ecb8:d540:dacb:8aff:fee4:74a0/tcp/8081"
And I have started the daemon with ipfs daemon --writable, it says it's ready.
The UI says it has discovered about 900 nodes, so why is mine not participating more actively in the network?
other nodes can't store content into your node automatically. There is public ipfs gateway list somewhere, submit your node to it.
run DHT server
ipfs config Routing.Type dhtserver
