[TiDB Usage Environment] Test Environment
[TiDB Version] v6.1.0
[Reproduction Path]
[Encountered Problem: Problem Phenomenon and Impact]
Yesterday, I experimented with dumpling, lightning, and sync, and modified some environment variables. After the test was completed, I didn’t perform any other operations. Today, it won’t start up, showing an unknown component. I tried updating the cluster component and similar actions, but none worked. There is a snapshot that can restore it to normal, but I want to know how to solve this issue, or if a newbie made a mistake. I hope the experts can provide some guidance.

It also says that the cluster component was not found, possibly deleted, but the files are still in the cluster path.

Did you use the same user for testing yesterday and today? Try both the root and tidb users.

| username: 气死人的萌新 | Original post link

Yes, it’s the same user who has been using TiDB all along.

When executing the command, you are using the root user, right? Try switching to the tidb user.

Check if the contents inside /root/.tiup/components/cluster are still there.

I have always used the root user to execute commands.
This is my configuration file at that time.

I just found out that the monitoring is actually working, all components are online, it’s just the cluster that’s having issues.

For standard deployment, it should be done under the tidb user. You can try switching to the tidb user and then executing the tiup command.

Take a look at what your tiup mirror is set to with tiup mirror show. If you can access the internet, you can set it to this:

tiup mirror set

Execute tiup mirror merge ../tidb-community-toolkit in the server directory…

Then check if your components are still in
If not, after setting the above mirror, you can re-download them.

Redownload, it’s safer.
