2. Access the logs: aws s3 ls s3://log -bucket/logs/ 3. Analyze logs for access patterns and anomalies. Explanation: Access logs provide insights into bucket usage and help identify unauthorized or unusual activity. Set up bucket replication to replicate only specific prefixes in a multisite RADOS Gateway. ee the solution below. Solution: 1. Create a replication policy (replication.json): { "Rules": [ { "Prefix": "documents/", "Status": "Enabled", "Destination": { "Bucket": "arn:aws:s3:::destination -bucket" } } ] } 2. Apply the policy: aws s3api put -bucket -replication --bucket source -bucket --replication -configuration file://replication.json 3. Verify replication: Upload an object with the specified prefix and check its replication. Explanation: Prefix -based replication allows targeted replication of specific objects, optimizing resource usage. Configure S3 object versioning and test restoring an older version of an object.
ee the solution below. Solution: 1. Enable versioning: aws s3api put -bucket -versioning --bucket bucket -name --versioning -configuration Status=Enabled 2. List object versions: aws s3api list -object -versions --bucket bucket -name 3. Restore an older version: aws s3 cp s3://bucket -name/object -key --version -id <version -id> /path/to/restore Explanation: Versioning protects data by keeping multiple versions of objects, enabling recovery from accidental deletions or overwrites. Configure S3 bucket analytics to monitor access and storage metrics. ee the solution below. Solution: 1. Define an analytics configuration (analytics.json): { "Id": "AnalyticsConfig", "StorageClassAnalysis": {} } 2. Apply the configuration: aws s3api put-bucket -analytics -configuration --bucket bucket -name --id AnalyticsConfig --analytics - configuration file://analytics.json 3. Verify analytics: aws s3api get -bucket -analytics -configuration --bucket bucket -name --id AnalyticsConfig Explanation: Bucket analytics provides valuable insights into storage patterns and helps optimize costs and resource
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:
usage. Create a Red Hat Ceph Storage file system with two active metadata servers. ee the solution below. Solution: 1. Enable the CephFS module: ceph mgr module enable cephfs 2. Create the file system: ceph fs create myfs myfs_metadata myfs_data 3. Deploy two active MDS daemons: ceph orch apply mds myfs --placement="2" Explanation: Creating a Ceph file system involves defining metadata and data pools, and deploying metadata servers for managing file metadata. Verify the health and status of the Ceph file system. ee the solution below. Solution: 1. Check the file system status: ceph fs status myfs 2. Verify the health of metadata servers: ceph mds stat Explanation: Monitoring the file system status ensures it is operational and metadata servers are active and healthy.
Mount a CephFS file system persistently on a client node using the kernel driver. ee the solution below. Solution: 1. Install the necessary packages on the client node: yum install -y ceph -common 2. Add the mount entry to /etc/fstab: <mon -ip>:6789:/ /mnt/cephfs ceph name=client.admin,secret=<key>,_netdev 0 0 3. Mount the file system: mount -a Explanation: Persistently mounting CephFS allows seamless access to file storage across reboots using the kernel driver. Mount a CephFS file system using the FUSE driver on a client node. ee the solution below. Solution: 1. Install the FUSE client: yum install -y ceph -fuse 2. Mount the file system: ceph -fuse -m <mon -ip>:6789 /mnt/cephfs 3. Verify the mount: df -h | grep ceph Explanation:
The FUSE driver provides an alternative to kernel -based mounting, offering compatibility with older kernels or custom setups. Set a CephFS quota to limit directory size to 10GB. ee the solution below. Solution: 1. Set the quota for a directory: ceph fs quota set myfs /mydir max_bytes 10737418240 2. Verify the quota: ceph fs quota ls myfs Explanation: Quotas limit storage usage for specific directories, ensuring fair resource allocation and preventing overuse. Set a quota to limit the number of files in a CephFS directory to 1,000. ee the solution below. Solution: 1. Set the quota for the directory: ceph fs quota set myfs /mydir max_files 1000 2. Verify the quota: ceph fs quota ls myfs Explanation: File count quotas help manage directory utilization, ensuring users do not exceed the allocated file limits. Create a CephFS snapshot for a specific directory.
