Everything You Need to Pass: RedHat EX260

Solution: 1. Install Podman: yum install podman -y 2. Pull the Ceph container image: podman pull quay.io/ceph/ceph:v16 3. Run the container for Ceph Monitor: podman run --name ceph -mon -d quay.io/ceph/ceph:v16 mon 4. Verify the running container: podman ps Explanation: Using Podman to deploy Ceph containers is ideal for virtualized environments. The podman ps command confirms that the services are running. Modify Red Hat Ansible Automation Platform installation files to configure the Ceph Storage cluster and deploy it using Ansible. ee the solution below. Solution: 1. Navigate to the Ansible directory: cd /etc/ansible 2. Edit the configuration file (group_vars/all.yml): ceph_origin: repository ceph_repository: community ceph_repository_type: cdn 3. Run the Ansible playbook: ansible -playbook -i inventory.yml site.yml 4. Verify the installation:

ceph status Explanation: Customizing Ansible configuration files allows flexibility in deploying Ceph clusters. Ensuring the configuration matches the environment is crucial for successful installation. Install and configure Red Hat Ceph Storage on a physical system using Ansible roles. Verify the health of the cluster. ee the solution below. Solution: 1. Install Ansible Galaxy roles for Ceph: ansible -galaxy install ceph -ansible 2. Create a playbook to include the roles: - hosts: all roles: - ceph -ansible 3. Run the playbook: ansible -playbook -i inventory.yml site.yml 4. Check the Ceph cluster health: ceph health Explanation: Using roles simplifies the deployment process, allowing you to manage reusable configurations. The ceph health command confirms the cluster's health. Deploy a Ceph Storage server with OSDs configured on specific disks using Ansible playbooks. ee the solution below. Solution:

1. Update the inventory file: [osds] node1 ansible_host=192.168.0.10 device=/dev/sdb 2. Modify the playbook to include OSD configuration: osd_scenario: lvm osd_objectstore: bluestore 3. Run the playbook: ansible -playbook -i inventory.yml site.yml 4. Verify the OSD status: ceph osd tree Explanation: OSDs are the backbone of Ceph Storage. Properly configuring them ensures efficient storage and retrieval of data in the cluster. Install a Ceph Storage server on a virtual machine and validate the storage pool creation. ee the solution below. Solution: 1. Deploy the Ceph cluster: ansible -playbook -i inventory.yml site.yml 2. Create a new storage pool: ceph osd pool create mypool 128 3. Verify the storage pool creation: ceph osd pool ls Explanation: Storage pools are logical groups for storing data in Ceph. Creating and verifying a pool is a critical step in setting up the cluster.

Automate the deployment of a multi -node Ceph cluster using Ansible. Ensure that both MON and OSD nodes are configured. ee the solution below. Solution: 1. Define the inventory file: [mons] node1 ansible_host=192.168.0.1 [osds] node2 ansible_host=192.168.0.2 2. Run the playbook to deploy the cluster: ansible -playbook -i inventory.yml site.yml 3. Check the MON and OSD status: ceph mon stat ceph osd stat Explanation: Multi -node configurations enhance cluster redundancy and performance. Properly configuring MONs and OSDs ensures high availability. Deploy Ceph storage with custom CRUSH maps to control data placement. ee the solution below. Solution: 1. Create a CRUSH map: ceph osd getcrushmap -o crush.map crushtool -d crush.map -o crush.txt 2. Modify the CRUSH map: # Add rules or customizations

3. Apply the new CRUSH map: crushtool -c crush.txt -o crush.map ceph osd setcrushmap -i crush.map Explanation: CRUSH maps define how data is distributed across OSDs. Customizing these maps allows fine-grained control over data placement. Set up Ceph storage with authentication enabled and verify that clients require keys to access the cluster. ee the solution below. Solution: 1. Enable authentication in the Ceph configuration file: ceph config set mon auth_allow_insecure_global_id_reclaim false 2. Generate a client key: ceph auth get -or-create client.admin 3. Verify client access using the key: ceph -s --keyring /etc/ceph/ceph.client.admin.keyring Explanation: Enabling authentication adds a layer of security, ensuring only authorized clients can interact with the cluster. Deploy Ceph storage and configure BlueStore as the OSD backend for optimal performance. ee the solution below. Solution: 1. Update the playbook with BlueStore settings: osd_objectstore: bluestore

➢ TOTAL QUESTIONS: 479 Install a containerized Red Hat Ceph Storage server on a physical system using Ansible playbooks. Verify the installation. ee the solution below. Solution: 1. Install required packages: yum install ceph -ansible -y 2. Edit the Ansible inventory file (inventory.yml): [mons] node1 ansible_host=192.168.0.10 [osds] node2 ansible_host=192.168.0.11 3. Deploy the Ceph cluster: ansible -playbook -i inventory.yml site.yml 4. Verify the cluster status: ceph -s Explanation: Ansible playbooks automate the setup of a containerized Ceph Storage cluster. Verifying with ceph -s ensures the cluster is operational. Deploy a virtualized Red Hat Ceph Storage server using Podman and Ceph container images. Verify the containerized services are running. ee the solution below.
