Lotus miner running for 2 days without any byte power

Hi there, I have been running the lotus-storage-miner run for two days, but still shows no byte power. By running lotus-storage-miner info, I got “Byte Power: 0 B / 3.6PiB (0.0000%), Actual Power: 0 / 3.21 Pi (0.0000%), Miner Balance: 0, Sectors: Total: 1, PreCommit1: 1”. I don’t know what is going on right now because I did not see any apparent error in the miner log. Anybody help? Thanks a in advance.

Hi, is filecoin mainnet launched?

no, for now is 2th testnet, and the mainnet will launch at aug if everythig is going well.
