Lotus configure for storage provider

[de-authority]

Lotus has different configurations sections for different usage scenarios. For storage providers, there are currently only three sections to be concerned with, and this document will be kept up to date with the necessary configuration items.

api section

[API]
  # Binding address for the Lotus API
  #
  # type: string
  # env var: LOTUS_API_LISTENADDRESS
  # ListenAddress = "/ip4/127.0.0.1/tcp/1234/http"

  # type: string
  # env var: LOTUS_API_REMOTELISTENADDRESS
  # RemoteListenAddress = ""

  # type: duration
  # env var: LOTUS_API_TIMEOUT
  # Timeout = "30s"

Here, it is recommended to configure #ListenAddress = "/ip4/127.0.0.1/tcp/1234/http" as an intranet address, lotus does not need an external address to run, configure the intranet to communicate properly with the main network, and your storage provider node will be fine as long as it can connect with lotus for example: ListenAddress = "/ip4/192.168.1.110/tcp/1234/http"

backup section

[Backup]
  # Note that in case of metadata corruption it might be much harder to recover
  # your node if metadata log is disabled
  #
  # type: bool
  # env var: LOTUS_BACKUP_DISABLEMETADATALOG
  # DisableMetadataLog = false

In this section, if your log file is corrupt or too large, you may consider disabling this configuration DisableMetadataLog = true

split store section

[Chainstore]
  # type: bool
  # EnableSplitstore = false

This feature is still being tested, please use it with caution, if you turn it on and then turn it off, you will encounter the following error

Solution 1: link

Solution 2: Export snapshot with this option turned on, then turn it off and import snapshot

Other sections, if no special needs, keep the default
