ERROR_CLUSTERLOG_EXCEEDS_MAXSIZE

ERROR_CLUSTERLOG_EXCEEDS_MAXSIZE indicates that the persistent cluster log has grown beyond the allowed size. It can accompany unusually high event volume, repeated resource failures, or a long-running problem that was never resolved.

What to check

Preserve a copy of diagnostics before any retention or cleanup action.
Use the timestamps in Cluster.log and the System log to find the repeating failure that caused log growth.
Check free space and the cluster service health on all nodes rather than treating the log-size condition as the root cause.
