1. Create a multisite zonegroup: radosgw -admin zonegroup create --rgw-zonegroup=group -name 2. Add zones to the zonegroup: radosgw -admin zone add --rgw-zone=zone -name --zonegroup=group -name 3. Verify the configuration: radosgw -admin sync status Explanation: Multisite configurations replicate RGW data across multiple zones, providing disaster recovery and geo- redundancy. Audit Ceph cluster operations using Ceph’s audit log. ee the solution below. Solution: 1. Enable audit logging: ceph config set mon mon_audit true 2. View the audit logs: tail -f /var/log/ceph/ceph.audit.log Explanation: Audit logs provide detailed records of cluster operations, helping track changes and maintain compliance. Configure a Ceph RADOS Gateway (RGW) bucket with encryption for data at rest. ee the solution below. Solution: 1. Enable bucket encryption:
radosgw -admin bucket encryption put --bucket my -bucket --default -encryption -rule "AES256" 2. Verify the encryption configuration: radosgw -admin bucket encryption get --bucket my -bucket Explanation: Bucket encryption ensures that all objects stored in the bucket are encrypted at rest, enhancing data security. Set up automatic snapshot schedules for Ceph RBD images. ee the solution below. Solution: 1. Enable the snapshot schedule module: ceph mgr module enable rbd_support 2. Create a snapshot schedule: rbd mirror snapshot schedule add my -pool/my -image 6h 3. Verify the schedule: rbd mirror snapshot schedule list my -pool/my -image Explanation: Snapshot schedules ensure regular backups of RBD images, simplifying data protection workflows. Migrate a replicated pool to an erasure -coded pool without downtime. ee the solution below. Solution: 1. Create an erasure -coded pool: ceph osd pool create my -ec-pool 128 128 erasure my -profile
2. Set up a cache tier for migration: ceph osd tier add my-replicated -pool my-ec-pool ceph osd tier cache -mode my -ec-pool forward 3. Migrate the data: ceph osd tier remove -overlay my -replicated -pool Explanation: Using a cache tier during migration ensures seamless data access while transitioning between pools. Configure Ceph to send cluster health alerts via email. ee the solution below. Solution: 1. Set the SMTP server: ceph dashboard set -alert-smtp smtp.example.com 2. Add an email recipient: ceph dashboard set -alert-email admin@example.com 3. Test email alerts: ceph dashboard send -test-alert-email Explanation: ee the solution below. Email alerts notify administrators of critical cluster events, enabling quick re solution of issues. Enable and configure Ceph’s Prometheus integration for advanced monitoring. ee the solution below. Solution:
1. Enable the Prometheus module: ceph mgr module enable prometheus 2. Access the Prometheus endpoint: curl http://<mgr -ip>:9283/metrics Explanation: Prometheus integration allows advanced metrics collection, providing detailed insights into cluster performance. Restore a pool configuration from a backup file. ee the solution below. Solution: 1. Backup the pool configuration: ceph osd pool get <pool_name> all > pool -config.backup 2. Restore the configuration: ceph osd pool set <pool_name> <key> <value> Explanation: Backing up and restoring pool configurations ensures that critical settings are not lost during cluster updates or migrations. Set up bucket lifecycle policies to transition objects to a different storage class. ee the solution below. Solution: 1. Define the lifecycle policy in JSON: { "Rules": [ {
"ID": "TransitionRule", "Status": "Enabled", "Filter": {}, "Transitions": [ { "Days": 30, "StorageClass": "GLACIER" } ] } ] } 2. Apply the policy: radosgw -admin bucket lifecycle set --bucket=my -bucket --lifecycle=/path/to/policy.json Explanation: Lifecycle policies automate data movement to cheaper storage classes, reducing storage costs over time. Configure Ceph for multi -factor authentication (MFA) for access to the RGW. ee the solution below. Solution: 1. Enable the MFA plugin: ceph dashboard mfa enable 2. Set up MFA for users: radosgw -admin user mfa add --uid=<user_id> --authenticator=<mfa_type> Explanation: MFA enhances security by requiring additional authentication steps for accessing RGW resources. Enable OSD scrubbing and configure scrubbing schedules. ee the solution below.
➢ 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.
