What did you do?

  1. mount a NFS as the external storage for the redo log.
  2. create a changefeed with the redo enabled.

What did you expect to see?

the changefeed works normally

What did you see instead?

  • the changefeed cannot contact the NFS system.
  • the owner is blocked for a long time, around 8 minutes.
