I followed this tutorial to set up a private chain with PoA some days ago. And I run a PoA chain successfully. But today I restart my server. And I can't start (or get into?) the PoA chain which I set up with command parity --config node0.toml. I think it because I restart my server and the authority has changed...

The error information is:

Loading config file from node0.toml
2017-06-26 16:29:00  Starting Parity/v1.6.8-beta-c396229-20170608/x86_64-linux-gnu/rustc1.17.0
2017-06-26 16:29:00  State DB configuration: fast
2017-06-26 16:29:00  Operating mode: active
Consensus signer account not found for the current chain. You can create an account via RPC, UI or `parity account new --chain HyperAlbum-chain.json --keys-path /tmp/parity/node0/keys`.

And my node0.toml is:

[parity]
chain = "HyperAlbum-chain.json"
base_path = "/tmp/parity/node0"
[network]
port = 30300
[rpc]
port = 8540
apis = ["web3", "eth", "net", "personal", "parity", "parity_set", "traces", "rpc", "parity_accounts"]
interface = "10.4.20.69"
[ui]
port = 8180
[dapps]
port = 8080
[account]
password = ["node.pwds"]
[mining]
engine_signer = "0x00525DBE671740a5F943Cd49a3e7f7D46075B07e"
reseal_on_txs = "none"

So how to get into a PoA chain again if I restart it? Or maybe I can't restart the parity?

Thanks a lot. :)

  • What does parity say when you run it? Did you place a relative path for the chain spec or absolute path? (in the config) – Afr Jun 26 '17 at 7:29
  • Emmmmmm... Because I have redeployed my PoA chain so I can't tell waht did parity say. I will restart my server and tell it later. I Thanks your advice :) And I set the base_path in the node.toml that "/tmp/parity/node0", I don't know whether it is the "chain spec"? – YangYifei Jun 26 '17 at 8:18
  • I have edited my question and add the error now .Thanks~ :) – YangYifei Jun 26 '17 at 8:30
  • Oh no... I think I know why. Because I set the base_bash under /tmp. If I restart my server it well be delete... That's so embarrassed... Thanks! – YangYifei Jun 27 '17 at 3:02

:) Hah. With the advice of @5chdn, I checked my *.toml. And I found that I set my base_path to /tmp,(and the tutorial set the same, too. So I think if you want to reconnect with your chain, don't set base_path like that.) in the Ubuntu the files under this folder will be deleted when power off... Thanks a lot~ :)
