| Configuration Management | Monitors store and manage the cluster’s configuration, allowing administrators to modify settings as needed. |
| Quorum Management | Monitors maintain a quorum of active Monitors to ensure that the cluster remains operational even if some Monitors fail. |
Adding and Removing Monitors in Ceph Clusters
At times, you may need to add or remove Monitors in your Ceph cluster. This process requires careful attention to ensure the stability and reliability of the cluster. Here’s a step-by-step guide to adding and removing Monitors:
- Confirm the status of the Monitors using the `ceph mon stat` or `ceph status` command.
- Stop the service of the problematic Monitor using the appropriate command for your operating system and deployment method.
- Remove the problematic Monitor from the cluster using the `ceph mon remove
` command. - Clear the Monitor’s data by deleting the relevant data directory on the Monitor node.
Mon in Minecraft
In the popular game Minecraft, Mon is a command that allows players to summon various entities, including mobs and items. The `/summon` command is particularly useful for creating custom experiences and solving in-game challenges. Here’s how you can use the `/summon` command to summon items in Minecraft:
