Is PD up? I suggest using just one TiKV for testing… resources are too limited.
Please send more of the log context.
All other nodes are up, only TiFlash is not starting?
The display shows up, but an error occurs when starting.

Resources are probably insufficient; the memory is almost at 100%.
Isn’t 8GB of memory too little? It will work if you switch to a more powerful machine.
Indeed, after switching to 24G, there were no errors.
For testing, just use one KV instead of three, it can save a lot of memory.
Can I directly use tiup to scale down?
If you need to set the cluster’s KV to a single replica and then shrink it, you can tinker with it if it’s a test environment.
