When you activate maintenance mode, Redis Enterprise does the following:

1. Checks whether shutting down this node would cause quorum loss. If so, maintenance mode will not activate.

1. Checks whether the cluster has enough active nodes to maintain quorum if one goes down. If taking a node offline would cause quorum loss, maintenance mode will not activate.

This check does not verify that the majority of nodes in the cluster are not in maintenance mode. Do not activate maintenance mode on the majority of nodes and restart them simultaneously, as this can cause quorum loss and data loss.

This check does not consider if other nodes are already in maintenance mode. Do not put the majority of nodes into maintenance mode and restart them simultaneously, as this can cause the cluster to lose quorum and lead to data loss.

1. If no maintenance mode snapshots already exist or if you use `overwrite_snapshot` when you activate maintenance mode, Redis Enterprise creates a new node snapshot that records the node's shard and endpoint configuration.
