| 2. Set `ozone.om.ratis.log.purge.upto.snapshot.index` to `false`. | ||
| This property prevents the leader OM from purging any logs until all followers have installed the latest snapshot. | ||
| This ensures that the new OM will have enough time to download and install the snapshot without the logs being purged. This is a more risky approach since it might cause the Raft logs to increase indefinitely when the OM follower is down for a long time, which can cause OM metadata dir to be full. | ||
| <br/>Note: If `ozone.om.ratis.log.purge.preservation.log.num` is set to a non-zero number, it is recommended to keep `ozone.om.ratis.log.purge.upto.snapshot.index` to `true` (default value) since `ozone.om.ratis.log.purge.upto.snapshot.index` will override the preservation configuration. Therefore, these two properties should not be set together. |
