Change JSON filename/miner ID on local lotus add-miner command

[jochasinga]

As per step 11 in this local network doc.

Running this command:

./lotus-seed pre-seal --sector-size 2KiB --num-sectors 2

Generate the following output:

INFO	preseal	seed/seed.go:228	Writing preseal manifest to /Users/pancy/.genesis-sectors/pre-seal-f01000.json

Note that the miner ID prefix has changed from t to f and the file written to is now pre-seal-f01000.json. Therefore, the file name should be corrected in the command in step 14 from ~/.genesis-sectors/pre-seal-t01000.json to ~/.genesis-sectors/pre-seal-f01000.json.

Hey @jochasinga! Thanks for the ticket. I tried to repro the outlined issue, but I can´t get the same output as you:

I suspect that this difference comes from that you are on a binary that was built for mainnet? Can you check the output of Lotus -v and post it here?

In Filecoin we differentiate Mainnet and Devnnet addresses by the prefix f for mainnet addresses, and t for testnet/devnet addresses.

lotus version 1.23.1-dev+mainnet+git.c6c23ec6d

Look like what I have is a mainnet version. I followed the instruction on the doc and clone the latest. How do I switch to devnet and should this be included in the doc?

Yeah, I would be interested to hear how you built you binary. As long as you are following the step in the tutorial where you make 2k, it should build the devnet binary.

Can you do ./lotus -v in your lotus-folder, and then lotus -v in som other directory. Maybe you have a older binary laying around somewhere, and you missed the sudo make install step that is outputted at the end of the make 2k logs

[jochasinga]

@rjan90 current make 2k fails at least on Mac OS 13.6.6 per #724. I had to run the go build command myself to supply the path to the missing dep.

So instead of running make 2k, I ran this with the additional path to hwloc:

go build  -ldflags="-X=github.com/filecoin-project/lotus/build.CurrentCommit=+git.082a9159c -extldflags=-L/usr/local/opt/openblas/lib -extldflags=-L/usr/local/opt/hwloc/lib" -tags=2k -o lotus ./cmd/lotus

So that might have caused it to build the mainnet binary.
EDIT: Looking at the 2k directive in Makefile, it seems so.
