How to handle the returned error when executing start-relay command for DM versions from 2.0.2 to 2.0.6?

flush local meta, Rawcause: open relay-dir/xxx.000001/relay.metayyyy: no such file or directory

The above error might be made in the following cases:

  • DM has been upgraded from v2.0.1 and earlier to v2.0.2 - v2.0.6, and relay log is started before the upgrade and restarted after the upgrade.
  • Execute the stop-relay command to pause the relay log and then restart it.

You can avoid this error by the following options:

  • Restart relay log:

    » stop-relay -s sourceID workerName
    » start-relay -s sourceID workerName
  • Upgrade DM to v2.0.7 or later versions.
