Why can’t I use curl -X POST http://192.168.2.160:2379/pd/api/v1/store/65531082/state?state=Up to bring a TiKV in Pending Offline state back up?
Pending Offline
is a critical state after the node offline operation. This state is maintained mainly to complete tasks such as leader migration and replica migration. Once these tasks are completed, it will transition to the tombstone state, and the offline operation can be completed.
Allowing elastic scaling up and down already provides significant convenience and ease of use. I’m not sure what your operational goal is?
I personally suggest learning some related knowledge about the TiDB series…
If you want to stop the offline process, this state has been maintained for about four days. Forcing a scale-down might result in data loss.
It’s done. After restarting TiKV, the node status has been restored!
As long as the number of replicas is sufficient, data will not be lost. Alternatively, you can forcibly evict the region leader of the node when performing the offline process.
Feel free to mess around in the test environment, but it’s better to be cautious online…
