Original topic: 提示:source is added but there is no free worker to bound

| username: TiDBer_xzeqSVEp

[Encountered Issue]
When loading the data source, it prompts: source is added but there is no free worker to bound.
Then, when testing if it can start, it prompts: “msg”: “pre-check is passed.”
When actually starting, it prompts that the data source already exists: Message: source config with ID mysql-tidb already exists.
Then I changed the configuration name in the configuration file, but the same error occurred.
Checking the DM status, I found that all three workers are in N/A status. Restarting still results in the same issue. Since I uninstalled version 4.0.0 and reinstalled TiDB version 5.4.2, with DM version 6.1.0, I really don’t know how to solve this. Seeking guidance from experts.

The issue has been resolved. If the dm-worker is in the N/A state, restart the DM cluster, and it will change to the bound state. Then stop the previously created data source.
