How to fix the gap between logs when restarting ConfigNode in Apache IoTDB?

Why did Apache IoTDB report IllegalStateException error when restarting ConfigNode? The error message is stated Found a gap between logs: the last log segment log-79627_94959 ended at 94959 but the next log segment log_inprogress_120859 started at 120859. I checked and seems no relevant questions to this error were asked. What may be the reason for this log gap, and how should I fix it?

This error is because part of the time series data in Apache IoTDB was accidentally deleted. I checked github and this bug seems to be fixed in 2023. (https://github.com/apache/ratis/pull/801) . Are you using a low IoTDB version? It is recommended to upgrade to Version 1.3 as soon as possible. At present, you can find the corresponding file directory, delete all logs before 120859, and then restart.
