Is progress the only problem, and does Tombstone Stores(2) in abnormal stores need to become Offline Stores(2) as well?

No, store will become offline store firstly and then become tombostone if offline is finished.

This issue arises because Grafana's progress gauge can only display the last data. In the code, when the scale ends, we directly delete the corresponding metrics. In this case, Grafana does not show a zero value but instead displays the last valid value.

Therefore, I plan to set the corresponding metric to 100% when the scale ends and wait for 1 minute before deleting the corresponding metric. This way, Grafana will be able to display correctly.
